June 30, 20242 yr We had an extended power outage overnight and I'm rebooting my Unraid system today. Now I can start the array, and it finds the array without problem (1 parity + 3x 4tb SSD). But it doesn't seem to mount my previous cache pool (2 x 2tb NVME, zfs, raid1) The cache pool drives are visible but now in unassigned devices section. As a result, system cannot find my docker vimage and appdata folders. Is there a best practice to remounting these drives to preserve my previous configuration? I'll attach diagnostics file and images below. Thanks! dunkn1nas-diagnostics-20240630-1110.zip

July 1, 20242 yr Community Expert Solution Add both pool devices to the pool and start the array, it should import the existing pool.
July 1, 20242 yr Author You're right - it worked just fine. Thank you! The error is still listed, however, when I run the "zpool -import" command. Not sure if I need to be concerned about that?

If you mean this you can ignore, this is parity, so it won't have a valid filesystem, but with an odd number of devices with the same filesystem, it can appear to have one.
