[05:01:22] <ScottCochran> hello all
[05:02:56] <deshantm> hello
[05:05:12] <ScottCochran> Sitting on hold with Citrix.... Client is having issues with External access
[05:05:24] <ScottCochran> The infamous "Protocol Driver Error"
[05:06:27] <deshantm> what product?
[05:06:50] <ScottCochran> XenApp 4.5
[05:07:15] <ScottCochran> Accessing from External using NetScaler/CAG gives that error
[05:07:23] <ScottCochran> Internal access is working fine...
[05:07:28] <ScottCochran> Firewall looks good
[05:09:31] <deshantm> I work more on the open source side. Xen.org stuff. I haven't used XenApp yet
[05:09:48] <deshantm> what do you use it for?
[05:09:54] *** Meson has quit IRC
[05:11:47] <ScottCochran> Citrix Access Gateway (CAG) provides SSL encryption for External users.  CAG is also now a feature built in to NetScaler appliances
[05:12:37] <ScottCochran> deshantm maybe you can help me with another issue I am having with XenServer
[05:15:10] <deshantm> ScottCochran: you can ask. I'll do my best to give suggestions
[05:16:10] <ScottCochran> I just built a XenServer 5.6 FP1 cluster and have migrated 30 physcial servers over the past 2 weeks.  Twice now the pool master's log file have filled up all the space in Dom0 causing it to crash.  It basically crashes the XAPI service.  I am able SSH to the host, delete the logs, reboot the sever, and it starts up working fine...
[05:17:14] <ScottCochran> The first time I changed the logs to keep only 5 instead of 20.  The second time was today and I changed it to 1 time but cant figure out why they are growing so big
[05:18:28] <deshantm> ScottCochran: can you pastebin the xapi log somewhere?
[05:18:37] <deshantm> even just a big chunk of it
[05:18:52] <ScottCochran> brb
[05:23:42] <ScottCochran> deshantm I dont see a XAPI log in the /var/log directory
[05:24:04] <ScottCochran> the other log files are the ones filling up and causing XAPI to crash
[05:24:18] <deshantm> ScottCochran: /var/log/xensource I think
[05:25:12] <ScottCochran> okay you want the Xensource.log?
[05:28:22] <deshantm> sure.. also which logs are the ones that are filling up specifically?
[05:29:54] <ScottCochran> pretty much all of them in /var/logs get big
[05:30:13] <ScottCochran> kernel, daemon, audit
[05:32:05] <deshantm> the xensource.log is the xapi log, so that might have some hints
[05:32:25] <deshantm> can you pastebin a few of the logs, probably it will turn out to be clear from the logs
[05:32:39] <deshantm> /var/log/SMlog is also a good one
[05:39:16] <ScottCochran> okay here is xensource, I will post SMlog in a minute....  https://docs.google.com/document/d/1YiNa1K2iyNpy57MgyTT9pxcnEsL5-5ZSZGIkX5EUD70/edit?hl=en
[05:41:52] <ScottCochran> deshantm here is SMlog ...  https://docs.google.com/document/d/1RESEzAh8UwBuacAD_sVRFQalpmNfCRomzqItuuvfT98/edit?hl=en
[05:54:25] <deshantm> ScottCochran: I'm back now...taking a look
[05:54:39] <deshantm> are they filling up currently?
[05:55:25] <deshantm> try running watch ls -lh /var/log/*
[06:00:19] <ScottCochran> sorry im back... I deleted them all this afternoon let me see
[06:04:34] <deshantm> ScottCochran: the other logs don't look too terrible
[06:05:09] <ScottCochran> deshantm they are definitely growing. Log folder is at 47 MB since about 4pm
[06:05:27] <deshantm> the unknown message rpc ones don't look great... but not likely the cause
[06:05:30] <ScottCochran> it will fill up the drive within a few days I suspecvt
[06:05:53] <deshantm> ls -lh /var/log/* to see which ones are biggest
[06:14:56] <ScottCochran> deshantm xensource.log is the biggest right now at 3 MB
[06:16:28] <deshantm> ScottCochran: tail -f /var/log/xensource.log to watch what is being added
[06:16:36] <deshantm> see if you notice a trend of any kind
[06:23:54] <deshantm> be back tomorrow
[06:34:33] <ScottCochran> thanks
[06:38:11] <ScottCochran> deshantm seems like that RPC error keeps popping up every few second

[12:34:33] <GrimdinWork> hi all, we have problems with FP1, is it possible to convert FP1 pool back to 5.6.0? eg. is it possible to join 5.6.0 server to 5.6.0 FP1 pool and migrate servers between them?

[18:50:15] <Alasdairrr> Is there a channel dedicated to Citrix XenServer?
[18:50:31] <jduggan_> not dedicated but alot of people here are using citrix xenserver
[18:51:32] <Alasdairrr> *nods*
[18:51:48] <jduggan_> myself included =]
[18:52:01] <Alasdairrr> I'm installing Windows Server 2008 x64 from a DVD downloaded from Microsoft's volume licensing download site, and the installer is complaining about missing drivers
[18:52:16] <jduggan_> huh
[18:52:19] <Alasdairrr> exactly
[18:52:21] <Alasdairrr> Someone suggested the issue is that the DVD image is probably corrupt
[18:52:28] <jduggan_> which version of xenserver?
[18:52:30] <Alasdairrr> I'm just redownloading using Microsoft's ghastly download manager
[18:52:59] <jduggan_> fwiw, i use the vlsc downloads in xen all the time, both 5.5 and 5.6
[18:53:04] <Alasdairrr> 5.6
[18:53:14] <jduggan_> im using 2008R2 almost daily without issue
[18:53:20] <jduggan_> i can give you an md5sum of the iso, if you want
[18:53:39] <Alasdairrr> Sadly I need 2008 non-R2
[18:53:41] <tabularasa> i like R2
[18:53:49] <jduggan_> i like R2
[18:53:53] <tabularasa> either missing drivers or bad RAM
[18:54:01] <tabularasa> er, bad DVD or RAM
[18:54:14] <jduggan_> yea id go with bad dvd
[18:54:20] <Alasdairrr> I wish Microsoft would supply MD5 sums
[18:54:59] *** ScottCochran has quit IRC
[18:55:19] <jduggan_> Alasdairrr:
[18:55:30] <jduggan_> crap
[18:55:31] <jduggan_> one sec
[18:55:56] <jduggan_> SW_DVD5_Windows_Svr_2008w_SP2_English__x64_DC_EE_SE_X15-41371.ISO
[18:56:03] <jduggan_> is that what you downloaded?
[18:56:14] <jduggan_> 2008 SP2 ?
[18:56:22] <Alasdairrr> Sadly not, SW_DVD5_Windows_Svr_DC_Ent_Std_2008_English_x64_MLF_X14-26714.ISO
[18:56:29] <Alasdairrr> I need it to be non-SP2 as well :-(
[18:56:33] <jduggan_> aaah
[18:56:36] <Alasdairrr> (Don't ask!)
[18:56:40] <tabularasa> lmao
[18:56:45] <jduggan_> i could probably get it from our spla
[18:56:48] <jduggan_> but
[18:56:49] <tabularasa> sounds like its doomed to fail already
[18:56:52] <jduggan_> no point
[18:57:01] <jduggan_> im guessing your re-download will work
[18:59:37] <Alasdairrr> We'll see! :-)
[19:11:13] <kreign> Alasdairrr, does the host in question have ecc ram?
[19:13:14] <Alasdairrr> kreign: It certainly does, and is quite happy running lots of other VMs
[19:13:23] *** finnzi has quit IRC
[19:13:24] <kreign> well, that's a relief then.
[19:13:26] <Alasdairrr> It's a Dell R410 with 2 x E5504 CPUs and 32GB of ram
[19:13:40] <kreign> it's been a long time since I've gotten a corrupt iso, but I think every single one of them has been from msdn.
[19:13:45] <Alasdairrr> If it was a memory error I'd be expecting MuchWorseThings[tm]]
[19:13:58] <kreign> yeah you'd have stigmata going on, totally
[19:14:01] <Alasdairrr> Yeah, they use akami and they seem to suck at large ISO files - this isn't the first time
[19:14:25] <kreign> IDK who else uses them but I've only ever had issue with stuff from MS.
[19:15:50] <Alasdairrr> Bleh, downloading it via the download manager tool hasn't helped - same error
[19:16:13] <Alasdairrr> "A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD or USB flash drive, please insert it now."
[19:17:29] <Alasdairrr> http://forums.citrix.com/message.jspa?messageID=1420989
[19:17:40] <Alasdairrr> This definitely seems to suggest I'm getting a corrupt file
[19:17:53] <Alasdairrr> Perhaps the ISO is corrupt on the CDN Microsoft are using
[19:19:11] <kreign> Alasdairrr, would not be surprising.
[19:34:45] <Alasdairrr> Amazingly, "ejecting" and re-selecting the ISO from the dvd dropdown within xenserver has fixed it
[19:35:00] <Alasdairrr> doh, spoke too soon.. "Windows cannot access the required file..."
[19:38:38] <kreign> nice.
[19:39:34] <Alasdairrr> I'm going to attempt to mount the ISO via the Dell's DRAC card, so that Citrix sees it as a "real" DVD in the local DVD drive
[19:41:57] <Alasdairrr> that worked
[19:42:00] <Alasdairrr> lame
[19:42:07] <kreign> Alasdairrr, not sure how to try it, but you could mount the iso on the host underneath shared storage, maybe
[19:42:10] <kreign> Alasdairrr, :|
[19:44:47] <kreign> hmm
[19:45:19] <Alasdairrr> I'm making the ISOs available to XenServer via an NFS share from a Sun 7210 SAN
[19:45:33] <Alasdairrr> works fine for Linux ISOs
[19:45:42] <Alasdairrr> although the Windows ISOs are > 2GB
[19:46:14] <Alasdairrr> that said, the debian and centos ISOs are >4GB :)
[19:46:16] <Alasdairrr> weird

[20:40:17] *** Guest16668 is now known as chimera21
[20:40:39] <chimera21> i have some performance issues in a customers env
[20:41:05] <chimera21> Write Cache on local HD but on SAN LUN's
[20:44:40] <chimera21> any helpful comments appreciated
[20:50:04] <rev78> we're just starting to play with provisioning server here, all i can say so far is pay extra attention to what quality of switches you are using
[20:50:32] <chimera21> Cisco the whole way thats what i know for sure
[20:50:37] <rev78> ok
[20:50:48] <rev78> none of the cheap cisco linksys ones right?
[20:51:08] <chimera21> nope
[20:51:30] <chimera21> there is a regkey called "ClusterSize"
[20:51:49] <rev78> what symptoms are you seeing?
[20:51:57] <chimera21> if there is anyone who had to use it in a environment please stand up :)
[20:52:08] <chimera21> huge performance problems
[20:52:13] <chimera21> vsphere 4.1
[20:52:51] <chimera21> the strange is that there performance lags but it seems as there arent any queues on the hds
[20:53:13] <chimera21> like write or read queues on the hd are high or something
[20:53:16] <chimera21> thats all fine
[20:53:41] <chimera21> but i think more and more about the alignment of the 4k blocks on the netapp and the writecache partition laying in the san
[20:54:04] <chimera21> therefore there is that regkey out of the pvs patch
[20:54:42] <tabularasa> using Dell servers?
[20:55:08] <tabularasa> and the 4k blocks doesn't matter on 2k8 or Win7... it aligns by default now
[20:55:10] <chimera21> the esx are HP
[20:55:20] <tabularasa> c-states disabled ?
[20:55:51] <chimera21> hm?
[20:56:20] <chimera21> can you explain that regkey for me? I dont get it i guess
[20:56:24] <chimera21> i mean
[20:56:39] <chimera21> i did know that the vdisks are aligned by default on 2k8
[20:56:42] <tabularasa> BIOS setting
[20:57:05] <chimera21> okay i didnt know
[20:57:07] <tabularasa> known performance issues with c-states
[20:57:27] <chimera21> okay what are c-states exactly?
