Unable to import ZFS volume into FreeNAS 11

[victorhooi]

Hi,

I had a NAS previously running FreeNAS 10 (Corral) on it, with a single ZFS volume (RAIDZ-1, compromised of 3 disks - 1 of which was in the process of being replaced.).

I reformatted the boot USB, and installed FreeNAS 11 on it:

• FreeNAS-11-MASTER-201705270409 (d3f5254)

I bypassed the initial setup wizard (because I've had issues before with it hanging at the AD step) - and then went into volumes, and tried to import the previous volume - however, for some reason it didn't appear.

I SSH-ed in as well, here is the output of zpool status and zpool import:

Code:

root@angfamilynas:~ # zpool status
  pool: freenas-boot
 state: ONLINE
  scan: none requested
config:

	NAME		STATE	 READ WRITE CKSUM
	freenas-boot  ONLINE	   0	 0	 0
	  da0p2	 ONLINE	   0	 0	 0

  state: DEGRADED

 action: The pool can be imported despite missing or damaged devices.  The
	fault tolerance of the pool may be compromised if imported.

		16014814109208190310						UNAVAIL  cannot open

I then imported it manually using :zpool import -f angfamily". (I had to use -f, as it was previously used on another system - actually the same system).

I rebooted FreeNAS - but it's still not showing up under Volumes in the FreeNAS GUI - furthermore, even though zpool status shows it there, it doesn't show up under mount, for some reason:

Code:

root@angfamilynas:/mnt # mount																																											  freenas-boot/ROOT/default on / (zfs, local, noatime, nfsv4acls)
devfs on /dev (devfs, local, multilabel)
tmpfs on /etc (tmpfs, local)
tmpfs on /mnt (tmpfs, local)
tmpfs on /var (tmpfs, local)
freenas-boot/grub on /boot/grub (zfs, local, noatime, nfsv4acls)
fdescfs on /dev/fd (fdescfs)
root@angfamilynas:/mnt # zpool status
  pool: angfamilynas

	the pool to continue functioning in a degraded state.

Any ideas of how to get the FreeNAS GUI to recognise this volume?

Thanks,

Export it in the CLI and import it in the GUI.

 

[victorhooi]

Hi,

OK, I've just exported it - output of that, and zpool status/import afterwards is below:

Code:

root@angfamilynas:/mnt # zpool export angfamilynas
root@angfamilynas:/mnt # zpool status
  pool: freenas-boot
 state: ONLINE
  scan: none requested
config:

	NAME		STATE	 READ WRITE CKSUM
	freenas-boot  ONLINE	   0	 0	 0
	  da0p2	 ONLINE	   0	 0	 0

errors: No known data errors
root@angfamilynas:/mnt # zpool import
   pool: angfamilynas
	 id: 16621537248281622998
  state: DEGRADED
 status: One or more devices are missing from the system.
 action: The pool can be imported despite missing or damaged devices.  The
	fault tolerance of the pool may be compromised if imported.

I logged into the GUI - and went to Storage, Volumes, Import - it still isn't showing up there:

Is there any debug information that might be helpful as to figuring out why the GUI doesn't seem to show that volume?

Regards,
Victor

 

[victorhooi]

Also - if it is somehow something to do with the volume being in a degraded state - is there some way to manually replace the disk without using the GUI?

My understanding is that the FreeNAS GUI adds a small swap partition to each disk, and does some weird offset/shift things - is there some way to replicate that via the CLI?

Regards,
Victor

Probably worth filing a bug on this, especially since FN11 is pre-release. If you do it through the GUI, a copy of your debug file will be attached.

 

[victorhooi]

I ended up installing "FreeNAS-9.10.2-U4.iso" - which seemed to detect the volume fine.

I then re-silvered the ZFS pool to replace the missing drive - and then installed "FreeNAS-11-MASTER-201705270409-d3f5254.iso" on the same USB - which was then able to pickup the volume fine.

So it seems that FreeNAS 11.x is somehow unable to pickup ZFS RAID-Z1 pools in a degraded state?

 

[indivision]

I seem to be in a very similar situation. Except that my volume is RAID10 rather than Z1.

FreeNAS 11.x GUI isn't finding the volume. It is degraded and has a bad drive.

I guess I will also try installing 9.10.2 to see if that works...?

 

[danb35]

So it seems that FreeNAS 11.x is somehow unable to pickup ZFS RAID-Z1 pools in a degraded state?

Perhaps. Did you file a bug as I suggested?

 

[Ericloewe]

I think someone has filed a bug report for that and I think a patch for it was suggested in the same ticket.

 

[indivision]

Well. Installed 9.10.2 U4. Doesn't find the network. Configure options don't work.

Try U5 I guess?

 

[indivision]

Ok. U5 found the network properly. The pool did import this time.

I physically replaced the drive. Is there somewhere in the GUI to start the resilver process?

If not, what are the steps to do that? I tried "zpool replace optimus ada3" and it didn't like that...

Ah. That Volume Status panel is kind of buried. Thank you. "Disk Replacement Process Initiated."
