After upgraded to 7.1.2 from 7.0.1, I noticed some odd behavior with some of the dockers.   I didn't see it at first, but my pool devices are "unmountable: wrong or no file system".  One drive is a 480gb ssd as cache drive and the other is 512gb NVME.  I haven't had any issues with this prior to the upgrade.

 

Not really sure where to begin troubleshooting this issue.

 

Thank you in advance.

Post the output from

 

wipefs /dev/sdb1

and

wipefs /dev/nvme0n1p1

 

Note that despite the name, this won't wipe anything as written.

Thanks for the quick reply:

wipefs /dev/sdb1:

DEVICE OFFSET       TYPE       UUID                                 LABEL
sdb1   0x0          xfs        b35ef0f4-e5c0-4c55-8d35-6415a6db5089
sdb1   0x6fc8544000 zfs_member 571767980592686562                   boot-pool
sdb1   0x6fc8584000 zfs_member 571767980592686562                   boot-pool

 

wipefs /dev/nvme0n1p1:

DEVICE    OFFSET       TYPE       UUID                                 LABEL
nvme0n1p1 0x0          xfs        bb6aadf8-f567-4f70-8402-e0795f75fe09
nvme0n1p1 0x773c0c4000 zfs_member 4843099954729049596                  data

 

 

The problem is the old zfs signatures, there are only being detected now because of a kernel change, you can use wipefs to wipe them, and it should be perfectly safe, I've used it before myself and with other users without issues, type:

 

wipefs -a -t zfs_member /dev/sdb1

and

wipefs -a -t zfs_member /dev/nvme0n1p1

 

This will delete the zfs signatures and leave only the xfs ones, after that, restart the array and the pools should now mount.

 

 

Ok, we'll give that a go!
Just want to make sure, should I stop the array prior to running those or it doesn't matter as they are not mounted?

It doesn't really matter.

And just like that, the devices are back online...

Thanks!

I did the wipefs -a -t zfs_member /dev/sdb1  command and now none of my zfs disks are mountable.

When I run wipefs /dev/sdb1, nothing is returned.

 

 

Any help would be appreciated here.

You should never run commands from a post intended for another user, if the devices were zfs, doing that would delete the zfs signature.
