[00:14:52] <kreign> modinfo bnx2 | grep version
[00:14:54] <makson> hey kdavy_ - i been dealing with uverse today... and the last 2 weeks!!! bunch of issues with the service
[00:14:56] <kreign> if I may ask
[00:14:58] <kreign> tabularasa, or you :)

[00:15:45] <tabularasa> I'm in the car using droid voice recognition
[00:16:05] <makson> tabularasa: your typing on IRC using droid voice!??!!?
[00:16:11] <kreign> kdavy, hmm and are you using that card?
[00:16:20] <tabularasa> that is correct
[00:16:24] <kreign> tabularasa, wow cool.
[00:16:29] <makson> that is awesome, what irc client?
[00:16:38] <makson> that is really cool
[00:16:43] <tabularasa> texting and driving is dangerous #### that
[00:16:58] <kdavy_> kreign: what card? lol. i have no idea what bnx2 stands for
[00:17:01] <makson> yah, but how are you on IRC? don't u use ssh client to irssi box?
[00:17:19] <tabularasa> it's a droid program called Irssiconnectbot
[00:17:21] <kreign> kdavy, broadcom gigE
[00:17:30] <kreign> kdavy, was that 5.6 or 5.6 fp1?
[00:17:47] <tabularasa> that program is an ssh client which are used to that the stage to my server
[00:17:48] <kreign> 07:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12) <-- or similar
[00:17:59] <kreign> tabularasa, hah! you're talking like a romanian!
[00:18:00] <kdavy_> kreign: yeah i have broadcom gige. and 5.6fp1
[00:18:00] <makson> damn... now i want a droid.
[00:18:17] <tabularasa> once inside of irssi it has cooled shortcut
[00:18:24] <kreign> anyone have any 5.6 non-fp1 they oculd check for me?
[00:18:28] <makson> tabularasa: meson3902
[00:18:29] <tabularasa> yes you have to talk like a robot for it to work
[00:18:31] <makson> is tweet name
[00:18:33] <kreign> kdavy, they really pusehd the kernel version along a couple ticks, didn't they...
[00:18:45] <tabularasa> thank you
[00:18:56] <kreign> 2.6.18 up to .32... hmm
[00:19:28] <kdavy_> kreign: i guess, i don't pay attention to such details :-p
[00:19:32] <makson> kdavy_: had bunch of issues most got fixed today was last one.. netflix keeps rebuffering and dropping off, it appears if someone along the line is throttling connection. They kept saying it was inside wiring issue. but the engineers just wouldn't run new wire.
[00:20:01] <tabularasa> okay back to driving thanks again
[00:20:17] <kreign> kdavy, i'm tasked with "I don't care if it's the right answer or not I need a solution, despite the fact that the cause of the problem is my fault, you can't do anything about it, and you've made several accomodating solutions in the interim already which would alieviate the issue"
[00:20:31] <kdavy_> tabularasa: can you recite all citrix products? i wanna ssee how voice recognition works for them lol
[00:21:18] <makson> so finally some guy today came and said they don't fix netflix issues! long story short he say's it happens because of the firewall on the uverse device and he's going to put the xbox on the dmz... so he configures it of course when he is here everything works lol. When he leaves i look at the firewall config and he has the wrong IP setup in the DMZ. did some more research online and it looks it is in fact the firewall on there gateway. i hate to stick
[00:30:19] <taranto> hey guys, Anyone know a good tutorial to enable ipv6 on XenServer?
[00:36:01] *** The_Machine has joined #Citrix
[00:36:11] <kreign> anyone here running non-fp1 5.6?
[00:37:10] <kreign> taranto, iirc xs doesn't support ipv6.
[00:37:26] <kreign> taranto, and you don't want to monkey with things on xs unless you want breakage down the line.
[00:37:44] <kreign> taranto, this would be your best bet: http://support.citrix.com/article/CTX123691
[00:41:31] <taranto> kreign, xs dont support ipv6 but have notice from citrix developers to change this?
[00:41:42] <kreign> taranto, ... I don't know.
[00:41:49] <kreign> i'm not sure what you even just said
[00:42:01] <taranto> ok
[00:42:26] <kreign> shit i wish one of you guys had a 5.6 machine sitting around.
[00:44:04] <taranto> kreign, but at some point the software will not support this type of protocol may affect the vms with ipv6?
[00:45:25] <kreign> taranto, yeah, this is true.
[00:45:36] <kreign> kdavy, did you/have you had any throughput issues with broadcoms?
[00:46:17] 
[00:46:30] <taranto> ops
[00:46:48] <taranto> kreign,   I can not believe that Citrix has not yet established a software upgrade to support IPv6
[00:48:15] <kreign> taranto, I don't work for 'em.
[00:48:56] <kreign> taranto, do you need ipv6?
[00:49:07] <Rienzilla> another guy yesterday had ipv6 for guest systems on xs5.6 working
[00:49:16] 
[00:49:25] <kreign> taranto, as many people that don't understand ipv4, I can't even imagine what a clusterfuck it would be if every iface had ipv6, and ipv6 became the 'default'
[00:49:29] <taranto> yes I know, I'm just sharing information
[00:49:38] <Rienzilla> and I don't see why that wouldn't work since the networking is level 2
[00:49:49] <kreign> i think it's the migration that has issues
[00:49:53] <kreign> but yeah
[00:49:56] <kreign> should just be a bridge
[00:50:10] <kreign> i don't know why you'd want to, but I suppose it's possible.
[00:50:13] <kreign> xs itself, does not
[00:50:15] <kreign> iirc
[00:51:08] <taranto> kreign,  yeah
[00:53:18] <tooms> whats the best antivirus to use on citrix terminal servers?
[00:53:28] <tooms> currently running forefront and it appears to be crap
[00:53:46] <taranto> kreign,  thks dude
[00:54:18] <kreign> taranto, what's wrong with forefront?
[00:55:31] <kreign> taranto, I can't speak of citrix term servers, but eset's products have been really impressive... and they're citrix/vmware partners or some such thing.
[00:56:08] <taranto> kreign,  understand
[00:57:49] <kreign> taranto, i've not used forefront but i'm curious what's wrong with it. the desktop versions i've been pretty satisfied with, more or less.
[01:01:10] <taranto> kreign,  my only problem with xenserver is that don't supports ipv6
[01:02:23] <kreign> taranto, stick around you'll have some more soon enough.
[01:04:02] <taranto> kreign,  sorry but my english dont good
[01:04:33] <charley> tooms: eset
[01:04:47] <taranto> but that are something thaht I dont understand
[01:05:33] <kreign> where are you from taranto ?
[01:05:52] <kreign> google does wonders: http://www.eset.com/
[01:06:46] <taranto> kreign,  brazil
[01:07:35] <kreign> ah
[01:07:55] <kreign> taranto, at any rate, I've not seen e-set brick anything and it usually has seemingly better early detection rates.

[03:50:43] <yonith> would xenapp work if i installed it on windows 7?

[04:01:49] <makson> yonith: that won't work.

[16:48:47] *** KidCrims has joined #Citrix
[16:51:52] <KidCrims> <albech> have you tried the command xe host-enable

[16:53:04] <kdavy_> albech: what he said
[16:53:18] <albech> KidCrims, it works, but im wondering what disabled them?
[16:53:34] <kdavy_> albech: an update or an upgrade could've
[16:53:42] <kdavy_> or if you were reconfiguring something
[16:54:30] <KidCrims> <albech> I agree with kdavy
[16:54:45] <albech> interesting.. well im grateful if the guests come back up.. they are still booting ;)
[16:57:13] <albech> hmm i still dont see them as started
[16:57:36] <albech> and now i get 'No Operations Available' in the xsconsole
[16:57:38] <KidCrims> do you have access to xenserver console?

[17:08:43] <KidCrims> albech ... can you try to start this machine in another host?
[17:09:05] <albech> KidCrims, sorry i dont have other hardware to launch it on
[17:09:30] <albech> looking at the XenCenter the guest im trying to start shows as yellow
[17:10:15] <simon__> have you tried restarting the toolstack?
[17:10:15] <albech> and the storage that is attached to it appears not active
[17:10:16] <KidCrims> take a lot at the messages log if there are something wrong
[17:10:46] <KidCrims> is it a local storage?
[17:11:15] <KidCrims> do you have any other vm in this storage?
[17:11:22] <albech> yes
[17:11:24] <albech> and they are running
[17:12:02] <KidCrims> if the vm have the same storage and is running I dont think that you have a storage problem
[17:13:23] <KidCrims> albech try to run the command xe-toolstack-restart
[17:13:33] <KidCrims> note that your XenCenter will loose connection when you do this. Nothing will however happen to your running VMs
[17:13:57] <KidCrims> Reconnect with XenCenter (or let it reconnect by itself) and you should see your VM no longer in a stuck state.

[17:32:47] <albech> in particular i dont like line 2 :(

[17:38:32] <draygo> regarding line 2
[17:38:42] <draygo> can you write to your disk?
[17:39:55] <albech> i guess so.. i have been receiving mails on my mailserver which is running on the same physical machine just on another guest, but still using the same storage
[17:59:14] <KidCrims> albech what was change in your xenserver environment? upgrade? update? hotfix?
[17:59:45] <albech> i changed a nic on one of my guests
[18:00:55] <KidCrims> in the guest that the problem is happening or another one?
[18:01:19] <albech> its happening on both the guest i changed and two other ones
[18:04:29] <albech> it appears the machines that wont start are the ones that are installed from an iso that was shared from the machine i did the network changes on.. are there any linking somehow back to the installation media?
[18:04:54] <KidCrims> ah ... ok
[18:05:04] <KidCrims> try to eject the cd from this machines
[18:05:21] <albech> and commonly for them is also that i cannot 'activate' the volumes attached to the machines
[18:05:28] <albech> no cd in the machine
[18:05:38] <albech> they were isos on a cifs share
[18:07:16] <KidCrims> if you go to guest console the dvd driver on xencenter console is empty?
[18:07:51] <albech> the console does not show, since the machine is not running
[18:08:16] <KidCrims> click on eject in all the guests that are not starting
[18:14:06] <albech> KidCrims, hang on a sec.. i think i have solved it.. will get back to you in a sec
[18:17:42] <albech> i restored the cifs share that was shared from one of the guests and then the other clients would start again.. does that make sense?
[18:18:08] <KidCrims> yes ...
[18:18:42] <albech> why are they dependent on the cifs share that held the iso that was used for the install?
[18:19:21] <KidCrims> if you try to start a vm and this vm has a link to iso in the cifs repository and the cifs is unavailable the vm wont start]
[18:19:31] <albech> :(
[18:19:41] <albech> sorry to bother you for such a n00b thing :(
[18:19:51] <albech> i appreciate your dedication though
[18:19:59] <KidCrims> because of that i asked you to click in the eject bottom in all vms
[18:20:26] <albech> yes, but i could not eject them unless the vm was actually started
[18:20:47] <KidCrims> yes ... you need to force shutdown

[22:20:04] <kreign> so for whatever reason, people think it's OK to grab a handful of my mixed dried fruit if the container is on my desk and they come in.
[22:20:33] <kdavy_> kreign: slap them
[22:20:51] <kdavy_> kreign: question for you. do you know how to manually configure multipath on xenserver?
[22:21:43] <kreign> kdavy, are the multipath-tool and device-mapper packages installed?
[22:21:50] <kreign> multipath-tools
[22:22:06] <kreign> i've only done it on cent
[22:22:10] <kdavy_> kreign: yes. it's kind of a unique problem, let me paste what i asked in ##nexenta
[22:22:30] <kreign> kdavy, does your initrd have mpath in it?
[22:22:40] <kdavy_> i need to configure multipath I/O in CentOS/XenServer with zvols served via FC Target from rsf1-cluster nodes
[22:22:56] <kdavy_> my goal is for the CentOS box to acknowledge existance of two paths to the same LUN/zvol, one via each cluster node, where of course one path will be [active][ready] and the other [failed][faulty]
[22:23:18] <kdavy_> autodiscovery won't work here because the LUN is only active on one rsf1-cluster node at any point in time
[22:23:54] <kreign>  /etc/sysconfig/kernel should have the dm-multipath module w/ any qla* stuff at the end of the list/after the mp stuff... then mkinitrd -f mpath from cli
[22:24:07] <kreign> and enable the multipathd
[22:24:24] <kdavy_> and cluster nodes have different FC port WWN's
[22:24:38] <kreign> kdavy, this may be of help, though I think it may be a bit dated: http://www.softpanorama.org/Commercial_linuxes/Devices/multipath.shtml
[22:25:02] <kdavy_> kreign: multipathd is enabled. i'm afraid what i need can only be done by manually editing /etc/multipath.conf
[22:25:18] <kreign> kdavy, hmm paste it up somewhere, it's been like 3 years since I messed with it.
[22:25:49] <kdavy_> kreign: ok
[22:26:53] <kdavy_> i'm trying to get to this point: http://pastebin.com/cq713gcR
[22:27:02] <kdavy_> for the NEXENTA,COMSTAR target
[22:27:57] <kdavy_> but i'm getting this on every pool member but pool master: http://pastebin.com/KuvXdbvr
[22:28:17] *** OmNomSequitur has quit IRC
[22:28:20] <kdavy_> note the absence of LUN ID 1:0:4:1 from the second paste
[22:30:24] <kreign> kdavy, paste your mulitpath.conf
[22:30:34] * kreign bangs on the drum
[22:30:35] <kreign> :P
[22:30:38] <kdavy_> the Nexenta COMSTAR cannot do active-active multipath from both cluster nodes at once - that would've been too easy. it can only do active-down/down-active, with failover taking ~1 minute
[22:31:10] <kreign> kdavy, I'll admit I don't have the time today to actively look at this. :|
[22:32:07] <kreign> kdavy, and it's long enough in the past I'm not sure I'll be of much help.
[22:32:09] <kdavy_> kreign: i havent changed anything in multipath.conf yet, so far i was adding the LUN via xencenter
[22:32:24] <kreign> kdavy, let me see the conf tho, something might snap
[22:32:42] <kdavy_> and multipath.conf doesn't have a device{} section for vendor "NEXENTA"

[22:36:11] <kreign> kdavy, looks to have a device entry for your nexenta
[22:36:52] <kreign> might have to tweak a bit
[22:37:29] <kdavy_> kreign: mmm this is for iscsi though, i need FC. Or does it not matter?
[22:38:36] <kreign> kdavy, honestly I'm not sure. your conf doesn't have a compellant entry either.
[22:39:23] <kreign> kdavy, I think FC should be utilizing the same scsi subsystem in linux.
[22:39:33] <kreign> pretty sure all mass storage is on there now.
[22:39:42] <kdavy_> kreign: yeah, compellent is active-active so xenserver's autodiscovery picked up all paths right away - they use virtual WWNs across controllers
[22:40:01] <kreign> ah
[22:40:11] <kreign> kdavy, yeah specify your nexenta in the mp config
[22:40:26] <kreign> no promises but 'it might help' ;P
[22:41:10] <kreign> as for your config I'd put it in the conf as well
[22:41:35] <kdavy_> kreign: just gotta find the right config... all the docs i read so far are about as useful as a chocolate teapot.

[22:43:46] <kreign> kdavy, ok, i need to get back to this voip shit.
[22:43:50] <kdavy_> aha, that's good advice to set no_path_retry variable, just what i need in my setup since there will be periods of all paths being down
[22:43:56] <kreign> sorry i couldn't have had a tobacco answer. ;)
[22:43:59] <kreign> (cut and dried)
[22:44:51] <kreign> kdavy, also: man 8 multipath
[22:45:33] <Ownage> anyone have experience using infiniband interfaces with xenserver?
[22:45:41] <kreign> kdavy, point of interest: multipath on linux utilizes md, which is the same thing used for linux software raid.
[22:45:59] <kreign> kdavy, so mdadm and/or doing things that way may actually be 'simpler' in some ways. never tried it though.
[22:46:13] <kreign> Ownage, I looked into it. It's impractical.
[22:46:22] <kreign> Ownage, though the price advantage would be awesome.
[22:46:35] <Ownage> impractical howso?
[22:46:44] <kreign> don't think there are any infiniband supported devices.
[22:47:03] <Ownage> there aren't, you're right
[22:47:13] <Ownage> but that doesn't change anything in my case
[22:47:19] <kreign> Ownage, you may be able to shoehorn something in, though.
[22:47:33] <Ownage> really I'm thinking about does it work
[22:48:28] <Ownage> I've seen a few threads about it on the forums
[22:48:37] <Ownage> and it seems to work a breeze on centos
[22:49:00] <kreign> Ownage, it's linux, so the centos infiniband packages + the module dev kit
[22:49:23] <kreign> Ownage, from a practical standpoint the best way to do it might be to do it with IP over infiniband
[22:49:47] <Ownage> I used openib on centos and it worked with no building or anything
[22:49:48] <kreign> giving you a degree of levity if it comes to needing to change infrastructure
[22:49:54] <kreign> yeah.
[22:50:00] <kreign> Ownage, what it'll come down to is bundled modules.
[22:50:10] <kreign> I don't know what xs provides there (how generic it is)
[22:50:46] <Ownage> I know that overall the system is pretty malleable (spelling?)

[22:56:11] *** cdubya has quit IRC
[22:56:14] <seta> can i just ask for your opinion/advice?
[22:56:40] <Ownage> what do you want to know, again.
[22:56:49] <STefano> anyone has experience slow network performance using windows 2008 r2 in xenserver 5,6 and 5,6 FP1?
[22:56:50] <seta> sorry didn't see ur reply
[22:57:12] <seta> i have a xensrv 5.6 with a local SR (LVM) of 500GB
[22:57:20] <Ownage> STefano: I've experienced the opposite. check your network settings and other items first
[22:57:39] <seta> if i do an fdisk -l
[22:57:49] <STefano> i disable taskoffload
[22:58:08] <STefano> but nothing change
[22:58:18] <seta> i get output : c0d0 599.0 GB and a C0D1 599 GB
[22:58:33] <seta> this is correct as i've got a raid array of 1TB
[22:58:52] <Ownage> STefano: use iperf to find out your throughput
[22:59:00] <seta> but i want to extend the SR to use the remaining disk space without losing my vms/current sr
[22:59:04] <seta> is this possible?
[22:59:15] <Ownage> that's like the most common question
[22:59:29] <seta> yes i know and i found alot on lvextend command
[22:59:45] <STefano> 229 Mbits/s always the same value in 3 different pool and 14 different machine
[22:59:49] <seta> but from what i can see is that command works, but loses the raid redundancy for the entire volume
[22:59:51] <jduggan> would someone like to assist fixing a broken pool member?
[23:00:16] <jduggan> its attached, i just cant move anything to it or boot vms on it :(
[23:00:17] <Ownage> seta: what raid redundancy?
[23:00:27] <Ownage> jduggan: ssh to it
[23:00:38] <Ownage> STefano: how are you determining that it is 'slow'
[23:00:57] <STefano> but if i use windows 2003 or windows 7 or windows 2003 r2 i have the correct value around 1Gbits/s
[23:01:13] <jduggan> Ownage: im ssh'd to it...
[23:01:19] <STefano> my network connection is 1Gb
[23:01:22] <seta> from what i understand you create a second sr and then extend the first SR to use the second sr?
[23:01:25] <STefano> my switches is 1Gb
[23:01:28] <seta> or am i seeing it wrong?
[23:01:36] <Ownage> STefano: so you should NOT be getting 1Gbps on ANY vms or servers, EVER
[23:01:51] <Ownage> if you are showing 1Gbps on something, you are using a broken tool
[23:02:06] <Ownage> seta: are you using hardware raid?
[23:02:10] <seta> yes
[23:02:15] <STefano> no i can get around 1Gb/s in every o.s. that is not windows 208 R2
[23:02:29] <seta> as far as you could call an HP adaptec HW raid...0_o
[23:02:32] <Ownage> jduggan: first lets try this. /opt/xensource/bin/xe-toolstack-restart
[23:02:44] <STefano> using iperf, trasfering any kind of files etc, etc
[23:02:46] <Ownage> seta: so you have two 1tb drives in mirror?
[23:03:08] <seta> no i have 6x300GB in raid6
[23:03:12] <Ownage> STefano: then you don't understand your network architecture or you are lying about the results or the set up
[23:03:14] <seta> no i have 6x300GB in raid5 i mean
[23:03:28] <jduggan> Ownage: already tried restarting toolstack on both the pool master and the problematic node
[23:03:33] <Ownage> ok so you have 1500GiB of space raw
[23:03:44] <Ownage> jduggan: what does dmesg show you, anything useful?
[23:03:46] <seta> aprox yes
[23:04:01] <Ownage> seta: first of all, how do you want to expand this? by adding more drives? or what

[23:05:08] <jduggan> Ownage: ofcourse
[23:05:13] <jduggan> Ownage: there's nothing wrong with it
[23:05:21] <seta> no i have the drives installed in the array, but for some reason my collegue installed the xen with an SR of only 500GB instead of using the available 1000GB
[23:05:26] <STefano> why? my infrastructure is 1 Blc7000, HP Virtual connect, first pool 12x HP BL460c G1 and second pool is 3x HP BL460c G1, 2x HP 2810 switches
[23:05:29] <Ownage> jduggan: is this an Isilon cluster?
[23:05:57] <Ownage> seta: so basically you want to just extend it to the rest of the volume, right?
[23:06:07] <jduggan> Ownage: no NFS store
[23:06:24] <seta> yep that's right, but i do not want to lose my vm's running on the sr now
[23:06:32] <Ownage> jduggan: please type a complete sentence, I don't understand your clause
[23:06:33] <STefano> every connection is gigabits why only non windows 2008 R2 operating system gone around 1Gb/s?
[23:07:07] <Ownage> seta: ok, so there's two concerns you have: the current vms, and losing raid functionality, right?
[23:07:45] <seta> yes and maybe more if i forgot one :D i must admit i'm new to using xenserver especially with local storage for sr...
[23:08:07] <Ownage> seta: ok so you can forget about the raid idea. changing your lvm in this way has nothing to do with raid.
[23:08:17] <Ownage> seta: in short your raid will still work exactly how it is now
[23:08:31] <seta> ok that's nice
[23:08:32] <jduggan> Ownage: you asked me if its an isilon cluster, i replied saying no nfs store
[23:08:50] <Ownage> jduggan: no nfs store means what
[23:08:54] <Ownage> no nfs storage?
[23:08:58] <Ownage> no, nfs store?
[23:09:05] <jduggan> oh come on
[23:09:07] <Ownage> what are you saying
[23:09:11] <jduggan> no, its an nfs store
[23:09:18] <Ownage> what is an nfs store
[23:09:25] <jduggan> mount -t nfs
[23:09:27] <jduggan> ;)
[23:09:33] <Ownage> isilon cluster is an nfs server cluster
[23:09:43] <jduggan> its a regular nfs server, nothing fancy
[23:09:45] *** yonith|sleep has joined #Citrix
[23:09:46] <Ownage> ok
[23:09:50] <seta> so then i can just use lvextend on a live server without losing vms/downtime?
[23:10:08] <Ownage> seta: first of all lvextend doesn't do anything dangerous
[23:10:12] <Ownage> so yes
[23:10:19] <Ownage> it's the filesystem grow you would be worried about
[23:10:29] <seta> why?
[23:10:30] <Ownage> but typically there's 0 problems with that step, in my experience
[23:10:46] <Ownage> because the file system grow is the only part of the process that could do what you are afraid of
[23:10:58] <Ownage> resizing an lvm to be larger doesn't do anything to your data
[23:11:10] <jduggan> Ownage: im getting 'internal error: another frontend device is connected to this domain'
[23:11:22] <Ownage> data is written on filesystems, which needs to be expanded within that new lvm space
[23:11:41] <Ownage> jduggan: on the nfs server or on the xenserver?
[23:11:43] <seta> ok that's fine, the reason i need to resize is because of the freaking snapshot space allocation bug, which according to citrix should not happen in 5.6 but it's happening to me...
[23:11:52] <Ownage> what snapshot bug
[23:11:55] <seta> and the coalesce tool is not working for me so...
[23:12:19] <seta> take snapshot-->grow in disk usage delete snapshot-->usage does not lower
[23:12:28] <seta> sorry for the bad english :p
[23:12:44] <Ownage> I understand
[23:13:01] <jduggan> Ownage: to give you some history/background - I have a two node pool which has two nfs stores mounted to it.  the pool slave i shutdown all non-important vms, i live migrated the important ones, i put in maintenance mode and i shutdown from xsconsole.. put more ram in and booted up, brought out of maintenance mode and now no shutdown vms will start on this box and i cant live migrate any other virtual machien back to it
[23:13:09] <Ownage> I'd say just upgrade to the current version and you'll be ok with that one seta
[23:13:33] <Ownage> jduggan: yeah, it says it can't reach the nfs server
[23:13:43] <jduggan> Ownage: except check this..
[23:13:49] <seta> i try the coalesce tool described in KB , but it just replies the vm has no coalescable VDIs , but i'm 100% sure the space is allocated by deleted snapshots...
[23:14:22] <seta> yes i know i should upgrade but it's a live production server, and i can't upgrade for at least a month
[23:14:51] <Ownage> I understand
[23:15:06] <Ownage> if I were in your situation I would make a script which prunes them
[23:15:19] <Ownage> also, you can just make a new SR
[23:15:23] <jduggan> Ownage: rather than paste see here; http://tankengine.co.uk/~jduggan/nfs.txt
[23:15:25] <Ownage> and start doing your snapshots to that
[23:15:35] <Ownage> bypassing the lvm extending, etc
[23:15:38] <Ownage> no scary stuff
[23:15:53] <jduggan> Ownage: its browseable, i can mv files, i can create files, delete files.. im not sure what is going on :(
[23:16:01] <jduggan> Ownage: i can unplug and plug the pbd just fine
[23:16:07] <seta> hmmm i must look into that, but won't i still have the same issue even on other SR for snapshots?
[23:16:28] <Ownage> seta: yes you would. unless you fix that issue by pruning them or upgrading
[23:16:40] <seta> and how do i prune them then?
[23:16:57] <seta> or is this not recommended?
[23:18:07] <Ownage> sec, smoking
[23:18:38] <seta> no prob ;) enjoy
[23:18:53] *** STefano has quit IRC
[23:20:24] <seta> just did a check again, i deleted a ss and tried to coalesce but replies: VM has no leaf-coalesceable VDIs
[23:23:11] <jduggan> Ownage: any suggestions?
[23:23:31] <Ownage> check how many nfs fail messages are in dmesg
[23:23:39] <Ownage> then try to start a vm and look again
[23:23:52] <Ownage> sometimes you get that message somewhat randomly and it may not be related
[23:24:33] <Ownage> you may also enjoy removing it from the pool and then re-adding it
[23:26:27] <Ownage> seta: for now I'd say figure out how many snapshots you need, think about if you will be ok with making a new SR and putting them there
[23:26:43] <Ownage> in the meantime, figure out how to upgrade sooner
[23:26:57] <jduggan> Ownage: i think its a coincidental error - i just created a new vm on that nfs store, set its home server as that host and it failed to boot saying another frontend is connected to ths domain.... so i try doing it on the other NFS store and that is saying the same thing.. i dont think its specifically nfs at fault
[23:26:59] <Ownage> you can also see if the disks themselves are still listed
[23:27:08] <Ownage> you can also manually delete them from the SR
[23:27:32] <jduggan> Ownage: it created the vhd just fine so i know nfs is working - i think its lost some pool state/locking or something
[23:27:36] <Ownage> a simple xe snapshot-list and a xe-snapshot-param-list should help you figure out systematically which disks are being used and which aren't
[23:27:44] <seta> but i did a testinstall this morning of 5.6 FP1 and it had the exact same issue (it was an upgrade from 5.6 if that should be worth mentioning)?
[23:27:50] <seta> how can this be?
[23:28:08] <Ownage> I don't have the problem with 5.6 fp1 afaik
[23:30:20] <seta> maybe because the vm was running the entire time, ive read something about offline coalescing of the space...
[23:32:07] <jduggan> Ownage: ok ive got some vms started... i think this is a locking problem - do you know how to see the locks etc?
[23:32:13] <jduggan> Ownage: or indeed clear the locks
[23:32:20] <Ownage> I do not
[23:32:51] <seta> ownage , can i ask you one more question, than i'll be on my way and you can chill ;)
[23:33:40] <seta> cause i can see you get spammed with lots o questions
[23:34:20] <Ownage> you should see how many email threads I'm typing in and how many ssh and rdp sessions I'm working on too! thank you, coffee =)
[23:34:59] <seta> lol :D i'm happily enjoying my redbull and off hours work as well ;-)
[23:35:41] <seta> i'm wondering how you would say it's best to backup vms, as for now i connected a USB drive and do vm-export for the entire appliance
[23:36:24] <seta> from what i understand this is fine, cause i could easily import and boot them on another xen in case of disaster.
[23:36:50] <seta> but the export is very timeconsuming+vms need to shutdown.
[23:37:18] <seta> is there a way to export the vm once, and then export the snapshots i take ?
[23:37:42] <seta> or an incremental backup of the vm (if it's at all possible)
[23:37:45] <Ownage> don't use usb drives that's malarkey
[23:37:56] <seta> malarkey? :D
[23:38:00] <seta> wtf is that?
[23:38:03] <Ownage> badness
[23:38:09] <seta> why?
[23:38:23] <Ownage> Noun: Meaningless talk; nonsense.
[23:38:35] <Ownage> because it's slow and pointless
[23:38:39] <seta> i don't really have a choice since the client is a cheap bastard :p
[23:38:40] <Ownage> and manual
[23:38:48] <Ownage> here's what you may like to do
[23:38:57] <Ownage> 1. have a backup server
[23:39:20] <seta> 1 not an option :p client is cheap :p
[23:39:31] <Ownage> you are working only for a client?
[23:39:53] <seta> by client i mean customer
[23:39:59] <Ownage> do you not have an infrastructure?
[23:40:20] <seta> it's just one xen at a client site with 4 vms on it...
[23:40:55] <Ownage> and he wants the backups to be just sitting on a disk somewhere?
[23:41:29] <seta> yup
[23:41:54] <Ownage> well then yeah, that's what you do
[23:42:03] <Ownage> let me read what you said again
[23:42:19] *** yonith|sleep is now known as yonith
[23:42:22] <Ownage> I get what you mean
[23:42:34] <Ownage> there's no way to do that afaik
[23:42:48] <Ownage> you'll basically just do a snapshot and then export that to the disk each time
[23:42:53] <Ownage> and they will have no relation to each other
[23:43:05] <seta> normally we would host the client's vms on our ESX cloud, but the client is an insurance broker and needs to have ALL of his infra. under his own roof by law.
[23:43:15] <seta> so that's why...
[23:43:39] <seta> we backup all important files/data etc to our online backup, but the vm's are way too large to do that.
[23:44:41] <seta> but am i correct to assume that the entire exported vm is enough to import and boot them on another machine? because i use : vm-export vm= bla bla
[23:44:57] <Ownage> why are you doing vm-export?
[23:44:58] <seta> but now i read something about vm-export metadata=true?
[23:45:09] <seta> why shouldn't i ?
[23:45:12] <Ownage> that requires an offline machine
[23:45:23] <Ownage> are you shutting his vms off?
[23:45:36] <seta> yep with a cronjob
[23:45:44] <Ownage> malarkey
[23:45:48] <seta> shutdown - export - start
[23:45:50] <Ownage> you don't need to do that at all
[23:45:57] <seta> ?
[23:46:10] <Ownage> are you being serious? you're shutting his vms down to export them?
[23:46:11] <seta> as you can see, i really am a xennoob
[23:46:18] <Ownage> what is the purpose of doing that?
[23:46:30] <seta> because if i don't i can't export them...
[23:46:30] <Ownage> ok
[23:46:36] <Ownage> here's what you want to do
[23:46:42] <Ownage> right click vm -> snapshot
[23:46:48] <Ownage> or make a snapshot through the cli
[23:46:56] <Ownage> then you export THAT onto your drive
[23:47:02] <Ownage> 100% vm uptime during this process
[23:47:11] <seta> yes , but 100% sr usage too
[23:47:16] <seta> if i keep snapshotting
[23:47:39] <Ownage> snapshots take around 2-10 seconds or so normally
[23:47:45] <Ownage> vs hours of being off
[23:47:45] <seta> and another thing is i don't see how to export snapshot, only export-snapshot-to-template
[23:48:22] <seta> yes i do realize all of this, this is why i'm asking you for knowledge :p;-)
[23:48:27] <Ownage> template = vm with is-a-template set to true
[23:48:43] <Ownage> set it to false and now it's a vm again
[23:48:48] <Ownage> no difference otherwise
[23:49:08] <seta> so if i do snapshot-export-to-template i have enough to recover the entire vm in case the original breaks/corrupts?
[23:49:28] <seta> + i can use the said snapshot to revert to a previous state as well?
[23:49:46] <Ownage> yes
[23:50:08] <Ownage> but 'reverting' there would mean just firing up that vm and shutting down the one in production
[23:50:18] <Ownage> it's not live or anything
[23:50:22] <Ownage> (obviously)
[23:50:56] <seta> ok so to recapitulize : i right click, take snapshot, then cli- export-snapshot-to-template.
[23:51:16] <seta> i'm getting this, but if i then delete the taken snapshot from xencenter
[23:51:23] <Ownage> in 5.6fp1 you can just export it
[23:51:30] <Ownage> if 5.6 only allows template that's fine
[23:51:34] <Ownage> it's the same thing
[23:51:42] <seta> can i just run something like : import-snapshot
[23:51:51] <Ownage> no. it's not a snapshot anymore
[23:51:54] <seta> or do i have to deploy vm from template?
[23:52:00] <Ownage> export doesn't mean copy
[23:52:01] <seta> ok so it's an entire vm?
[23:52:09] <Ownage> export means make a whole vm from it
[23:52:10] <Ownage> yeah
[23:52:40] <seta> i see... and then i would have all the metadata etc.. needed to just import it to another xen in case of emergency
[23:52:51] <Ownage> if you export a snapshot you can light that server on fire and melt it to a puddle
[23:53:06] <Ownage> fire up a brand new xenserver, vm-import that xva file it made
[23:53:23] <seta> aha i see, but why would exporting that snapshot be faster than the vm itself?
[23:53:32] <seta> or do you just say this to avoid the downtume
[23:53:33] <Ownage> in your case the additional step would be to set is-a-template to false for that vm, OR just make a new vm from that template in xencenter
[23:53:47] <Ownage> it's not faster
[23:53:50] <Ownage> it's 100% uptime
[23:54:34] <seta> hmm that's indeed better, but than i still have the allocation problem for snapshots for now. until i upgrade.
[23:55:06] <Ownage> yeah
[23:55:13] <seta> i will look into this
[23:55:17] <Ownage> like I said you should be able to figure out which are rogues
[23:55:20] <Ownage> and nuke them
[23:55:31] *** kdavyd has quit IRC
[23:55:44] <seta> yeah but in this stage f xenknowledge, i think i won't go there :p
[23:55:48] <Ownage> in fact you can probably just make a script that kills all disks which aren't being used on a vm if that makes sense in your environment
[23:55:50] <seta> i think you will agree
[23:56:04] <Ownage> you gotta start somewhere ;-p
[23:56:18] <seta> yes but rather in testlab than customers site :p:p
[23:56:40] <seta> do you know anything about xenapp licensing as well by chance?
[23:57:20] <Ownage> nope, I don't use it
[23:57:23] <Ownage> only xenserver
[23:57:29] <seta> crap :p
[23:57:39] <jduggan> in xen terms, what is a 'domain'
[23:57:44] <jduggan> is it a virtual machine?
[23:58:05] <seta> no biggie, i thank you a lot for enlightning me :p;)
[23:58:11] <seta> 10000 internets to you
[23:59:12] <seta> and goodnight
[23:59:24] *** seta has quit IRC
