Try one more time with

zpool import -FX cache

if that still fails I'm afraid you will need to destroy the pool and restore from a backup.

[FTW]

okay, let me reboot and try again

 

if fails, to destroy I need to decrypt, and then

 

zpool destroy cache

??

[FTW]

nope, failed again 😪

[FTW]

thanks  a lot for your help JorgeB

[JorgeB]

To destroy the pool you just need to wipe the device, with blkdiscard for example, then re-format with Unraid.

[FTW]

ok thanks a lot!!

and if that happen to me again, is that mean the NVME are dead/faulty and need replacement or its because the server crashed during a write on the cache pool and should be fix with a backup?

[JorgeB]

If it happens again it could be an NVMe issue, or some other underlying issue, like bad RAM.
