[00:07:01] <metropolio> hi, i got a message when trying to log into nmc saying that license is invalid because we've exceeded our used space limit.
[00:07:10] <metropolio> but i'm pretty sure we haven't hit that limit
[00:07:25] <metropolio> how can i check what our actual usage is?
[00:10:47] <kdavy_> metropolio, what version of nexenta is it?
[00:10:56] <metropolio> kdavy_: 3.0.3
[00:10:57] <kdavy_> and have you added any new drives recently?
[00:11:04] <metropolio> nope
[00:11:38] <metropolio> it should be a 12TB license and we have 12TB of usable space on our RAID
[00:12:12] <kdavy_> i forgot when the change was made, in 3.0.4? "licensing is based on the amount of your overall raw capacity"
[00:12:57] <kdavy_> 3.0.3 might still be licensed based on overall used capacity. unfortunately i just upgraded my last 3.0.3 unit so i cant look that up
[00:13:13] <metropolio> gotcha
[00:13:39] <metropolio> but if our overall used capacity is below the 12TB limit, that makes no sense?
[00:13:40] <kdavy_> aha
[00:13:51] <kdavy_> go to "About" in the web gui
[00:14:10] <kdavy_> it will tell you License Maximum Capacity and License Utilized Capacity
[00:14:20] <metropolio> yeah...i can't
[00:14:32] <metropolio> i'm locked out of the web gui...because of said error
[00:14:44] <kdavy_> "show appliance license" ?
[00:15:09] <metropolio> when i try logging into nmc, it prompts me to enter in a new license key
[00:15:13] <metropolio> because of...said error
[00:15:51] *** anatoly_l has joined ##nexenta
[00:15:58] <kdavy_> "zpool list" then
[00:16:05] <kdavy_> from an ssh session
[00:16:39] <metropolio> this is what i get
[00:16:58] <metropolio> NAME      SIZE  ALLOC   FREE    CAP  DEDUP  HEALTH  ALTROOT data     18.1T  12.0T  6.11T    66%  1.06x  ONLINE  - syspool   928G  11.2G   917G     1%  1.00x  ONLINE  -
[00:17:01] <metropolio> whoops
[00:18:05] <kdavy_> metropolio, yep - your ALLOC is 12.0T
[00:18:07] <metropolio> huh
[00:20:02] <kdavy_> what do you mean by huh?
[00:20:23] <metropolio> it's just a surprise to me
[00:20:28] <kdavy_> aha
[00:20:47] <metropolio> is there a way to get a breakdown of what's being used in that particular pool?
[00:21:04] <kdavy_> "zfs list"
[00:21:53] <metropolio> kdavy_: and i should be double checking the USED column numbers?
[00:22:00] <kdavy_> if you use auto-snap at all, quickest way to resolve this would be to delete some old snapsjots
[00:22:08] <metropolio> sorry, i'm a zfs noob
[00:22:12] <kdavy_> yes, USED is what you need
[00:23:13] <metropolio> yah, i got rid of some old snapshots but they weren't taking that much space
[00:23:31] *** swy has quit IRC
[00:23:40] <kdavy_> actually... USED = REFER (actual current data) + snapshot sizes
[00:24:21] <metropolio> when i add up these numbers, it doesn't add up to 12T
[00:24:22] <kdavy_> i think... just add the numbers up and see if they make sense
[00:24:32] <kdavy_> what does it add up to?
[00:25:18] <metropolio> around 8TB
[00:25:51] <kdavy_> that's because zfs reports usage before RAID overhead, while zpool reports usage after raid overhead
[00:26:14] <metropolio> ohhh
[00:26:23] <kdavy_> for the same reason, AVAIL on the zfs is lower than FREE on a zpool
[00:26:33] <metropolio> so the license is based on usage with raid overhead?
[00:26:49] <metropolio> that would explain the change in 3.0.4
[00:26:53] <kdavy_> you think i remember? :) it's been so long since i bought 3.0.3
[00:27:04] <kdavy_> on 3.0.4 now
[00:27:19] <kdavy_> but logically, yes, i'd assume so
[00:27:22] <metropolio> so i guess i should upgrade
[00:27:49] <kdavy_> upgrade capacity or upgrade to 3.0.4?
[00:27:56] <metropolio> to 3.0.4
[00:28:34] <metropolio> seems cheaper :)
[00:28:58] <kdavy_> yeah but in 3.0.4 you will need a 32Tb license for your pool size...
[00:29:12] <kdavy_> call sales - maybe you can work something out with them. they're very reasonable
[00:29:20] <metropolio> sounds good
[00:29:22] <metropolio> thanks!
[00:29:26] <kdavy_> np :)
[00:30:11] <kdavy_> in the worst case they can give you a temporary larger capacity license that will expire in a month for example - plenty of time to make a decision
[00:30:26] <metropolio> oh, cool
[00:30:30] <metropolio> good to know
[00:31:16] <metropolio> we were gonna purchase one soon but i would like to be able to admin our system :)
[00:31:20] <metropolio> so this was a surprise
[00:34:33] <kdavy_> i can imagine
[00:35:02] <kdavy_> 3.0.4+ licensing is a lot more predictable in that extent - you don't add hardware often
[00:36:36] <metropolio> yah
[00:38:18] <metropolio> oh, so if our RAID setup is 24TB raw, then i'll need a 24TB license with 3.0.4
[00:38:25] <metropolio> which makes...sense
[00:38:40] <Triskelios> skip 3.0.4, upgrade to 3.0.5
[00:38:48] <metropolio> yah
[00:39:01] <kdavy_> Triskelios, that's why i said 3.0.4+ :)
[00:39:56] <kdavy_> some organizations have policies that prohibit using software that was released less than x months ago, even if it's a service pack release essentially
[00:40:41] <kdavy_> or something of that nature
[00:46:59] <kdavy_> metropolio, oh, make sure you reboot the nexenta once before the actual software upgrade - certain things like failed drives might prevent it from booting, and if you upgrade the fact that it doesn't want to boot may lead you in the wrong direction
[00:47:33] <kdavy_> i've had one case where the system got stuck even before the bootloader because of a drive that failed on reboot
[00:49:35] <Triskelios> we're not issuing dim sum patches, so support will direct you to 3.0.5 (or 3.1) if you have any problems with 3.0.4
[00:50:11] <metropolio> kdavy_: sounds good. i think we'll probably end up buying a larger license anyway which means we'll have support. yay!
[00:51:52] <kdavy_> Triskelios, only in the case where issue can be directly linked to a changelog entry in the newer version, no? what's the point of going through the upgrade to find out you're still having the issue?
[00:53:52] <kdavy_> and what are the chances of it being "magically" fixed by something unrelated?
[00:54:58] <kdavy_> in the enterprise, upgrade without a reasonable explanation is not an option.

[04:27:36] <victori> would disabling zfs cache flushing turning a resilver help speed it up?
[04:27:57] <victori> 48 hours to resilver 188gigs of data with a good a mount of snapshots
[04:27:59] <victori> kinda painful

[04:43:16] <victori> that is true

[08:00:05] <kdavy> Andys^: no thanks :)
[08:00:53] <Andys^> i might end up using triple RAID1
[08:01:23] *** matsimon_away has joined ##nexenta
[08:13:31] <victori> hah
[08:14:20] <kdavy> at some point mirroring to a brand new zpool will (if it isn't already) be faster and safer
[08:15:48] <kdavy> with vsphere, storage vmotion of all resources is pretty much an obvious solution
[08:15:56] <victori> I am trying a vmware experiment;   install snv98 boot into solaris-11 .. create new boot environment and rsync a solaris-11 install over the snv98 one
[08:15:58] <victori> see if it boots
[08:16:22] <victori> will it boot, who knows
[08:17:12] <victori> if it works, would be a decent upgrade path for my snv98 prod install

[10:26:26] <matsimon_mob> Hi I just could get my hands on some Qlogic HBAs, one is a QLE2462 2 are QLA2460, am I right all QL*24xx should work with QLT driver in FC target mode?
[10:28:25] <kdavy> matsimon_mob: i use both in production, so the answer is yes
[10:28:34] <kdavy> both as target and initiator
[10:32:03] <matsimon_mob> great :-)
[10:32:41] <matsimon_mob> Just got the dual one for 20 bucks, it's IBM branded, but don't think that should change anything
[10:32:51] <kdavy> lucky
[10:33:20] <kdavy> i'm using IBM branded ones as well, but they were several hundred bucks each
[10:33:44] <kdavy> still cheaper than getting the retail ones
[10:33:46] <Darkman_> i would take some for 20 bucks, too ;)
[10:36:06] *** kart_ has quit IRC
[10:36:43] <kdavy> but then again i got Xyratex FC arrays for $225 each (with 16 146Gb 10k drives and redundant ESMs and PSUs) - can't complain
[10:37:47] <matsimon_mob> I think was more because the used-parts reseller doesn't sell server stuff and just wanted to get them sold
[10:38:11] *** kart_ has joined ##nexenta
[10:38:25] <kdavy> yeah, it sounded like my reseller had no idea how much those arrays are worth, either
[10:38:27] <matsimon_mob> I mostly want to get my feet wet with FC but can't afford Fabric switch "just for fun" ...
[10:39:46] <kdavy> matsimon_mob: depends on budget... a QLogic 5600 is way less than $1k on eBay
