Cache pool lost after power outage


Go to solution Solved by JorgeB,

Recommended Posts

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!

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.
