unable to offline disk

[JJD]

I am trying to grow my pool by replacing my 3tb disks with 6tb disks following the directions here (http://olddoc.freenas.org/index.php/Volumes#Replacing_Drives_to_Grow_a_ZFS_Pool) however when i try to offline a disk i get the following error

Jan 8 22:54:39 freenas kernel: GEOM_ELI: Device ada0p1.eli destroyed.
Jan 8 22:54:39 freenas kernel: GEOM_ELI: Detached ada0p1.eli on last close.
Jan 8 22:54:39 freenas notifier: geli: No such device: /dev/ada0p1.
Jan 8 22:54:39 freenas manage.py: [middleware.exceptions:38] [MiddlewareError: Disk offline failed: "cannot offline gptid/c977fb55-8876-11e3-9900-74d435186bfa: no such device in pool, "]

I have no idea what to do about this. I have tried google but it was no help :( My volume scrubbed just recently no issues.

help!

Which FreeNAS version?

 

[JJD]

Sorry forgot to include that
FreeNAS-9.2.1.9-RELEASE-x64 (2bbba09)

Can you post the output of zpool status either within code tags or as a screenshot?

 

[JJD]

Of course!

Code:

 pool: Tank2

 state: ONLINE

status: Some supported features are not enabled on the pool. The pool can

still be used, but some features are unavailable.

action: Enable all features using 'zpool upgrade'. Once this is done,

the pool may no longer be accessible by software that does not support

the features. See zpool-features(7) for details.

no one has any ideas?

Aha! You got hit by a bug! https://bugs.freenas.org/issues/5035
I'm gonna send you a PM though... because if you are okay with it I'd like to have a dev look and see what is going wrong. We can't figure out what is broken. :P

cyberjock helped me get this fixed! Thanks!

my first drive is resilvering now and I'm very impressed with the speed!

resilver in progress since Thu Jan 15 20:09:59 2015
86.1G scanned out of 4.19T at 162M/s, 7h23m to go
43.0G resilvered, 2.01% done

and the time remaining seems to be dropping fast from the time i copied the above to the time i pasted it it had droped to 6h07m

For anyone that is curious, it's all documented in bug ticket 5035. In short, there's two options:

1. Offline the disk from the CLI with the GUID. Note that *only* the offline should be performed from the CLI, the remaining steps should be done from the WebGUI.
2. Upgrading the zpool to the latest feature flags seems to "fix" this issue.
