February 22, 20242 yr Community Expert 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.
February 22, 20242 yr Author okay, let me reboot and try again if fails, to destroy I need to decrypt, and then zpool destroy cache ??
February 22, 20242 yr Community Expert To destroy the pool you just need to wipe the device, with blkdiscard for example, then re-format with Unraid.
February 23, 20242 yr Author 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?
February 23, 20242 yr Community Expert If it happens again it could be an NVMe issue, or some other underlying issue, like bad RAM.
