Lost pool after config reset

[oops]

Hi all,

Solo pool of a mirrored pair has been running for a little over a month now with no issues on 11.2-U1

Reset config to defaults, as expected needed to remount pools. No other config changes were actually made past making a user and SMB share.

When I try to do so via GUI (Storage -> Pools -> Add -> Import an existing pool etc). Drive is not encrypted. When I get to select the pool it is not in the list.

Spec: E3-1220v6, 8GB ECC, BCM5720 NIC, two mirrored WD 4TB. Specifically this PowerEdge T130, with two WD MyBooks shucked.

zpool import (with and without -D) returns nothing.

gpart status returns

Code:

ada0p1 OK ada0
ada0p2 OK ada0
ada1p1 OK ada1
ada1p2 OK ada1
ada2p1 OK ada2
ada2p2 OK ada2

zpool status returns just the freenas-boot pool, freenas-boot and ada2p2 as online (0/0/0).

zdb -l /dev/ada0p1 etc returns "Failed to unpack" for all labels.

camcontrol devlist returns all drives.

Output of sqlite3 ..... "SELECT * FROM storage_disk;" (storage_diskgroup is empty)

Were you able to resolve this?

 

[oops]

Nope, not yet!

Thank you for your reply :)

 

[oops]

Bump - is there any more information I could provide, or did I do a really big oopsie? I have backups of course, but an understanding of how I could resolve this would be good (I would accept "Don't click the bleeding reset button again").

 

[dlavigne]

A config reset shouldn't touch the pool but it would be good to do an investigation on what happened if you haven't already restored the system. If it's still in the same state, please create a report at redmine.ixsystems.com that includes a debug. A dev may also want to schedule a teamviewer session with you and would contact you ASAP after the ticket is made.

To verify, did you try importing the pool using the UI? https://www.ixsystems.com/documentation/freenas/11.2/storage.html#importing-a-pool

Yup, once on the screen of Fig 9.2.6 the dropdown doesn't include the pool previously defined. First time using FreeNAS/ZFS so haven't tried much via CLI past the few commands listed in the original post. Will fill in a report now - thank you!

After resetting the config did you use the Wizard ?

I had the same issue, I reset, lost the pool and shares. I was able to import the disks & shares using the wizard but it the pool did not show (but somehow the share did!). I solved it by re-uploading my backed up configuration, then the pool and share showed properly again. This also fixed my original problem of the Dashboard showing no icons. If you have your backed up config, try uploading it.
