Hi,

 

I've upgrade my Unraid OS to 6.12.3 from 6.10.3.

Tried to import my existing ZFS pool and getting - Unmountable: Unsupported or no file system

 

Zpool is alive and well:

# zpool status 
  pool: SSD
 state: ONLINE
  scan: scrub repaired 0B in 00:02:51 with 0 errors on Tue Aug  8 00:15:09 2023
config:

	NAME                                        STATE     READ WRITE CKSUM
	SSD                                         ONLINE       0     0     0
	  raidz1-0                                  ONLINE       0     0     0
	    nvme-KXG50PNV2T04_TOSHIBA_************  ONLINE       0     0     0
	    nvme-KXG50PNV2T04_TOSHIBA_************  ONLINE       0     0     0
	    nvme-KXG50PNV2T04_TOSHIBA_************  ONLINE       0     0     0

errors: No known data errors

 

Any ideas?

Please post the diagnostics.

In the meantime my BTRFS cache pool died and another reboot seems to solved the ZFS issue.

Now thinking if i want to fix the cache or reinstall it as a new ZFS pool.

Likely you had the pool imported already before array start, Unraid needs to import the pool.
