August 27, 20232 yr I followed SpaceinvaderOne's video on converting my cache drive to ZFS, but I am unable to format it no matter what I try. It just keep coming up Unmountable when I start the array even after I try to format it. I have tried using the blkdiscard /dev/nvme0n1 -f command before and after a reboot, but still won' work at all. The drive has been working without issue before trying to do this. I have attached my diagnostics file. Edit: Well this is frustrating. I figured I would try to format as XFS to see what would happen and it worked flawlessly. I'd prefer to use ZFS if I could, but at least for now I can have my cache drive up and running until I can find a solution. vault-111-diagnostics-20230826-2038.zip Edited August 27, 20232 yr by Xcelsior86
August 27, 20232 yr Community Expert Solution root: mountpoint '/mnt/cache' exists and is not empty This mount point should not exist before the device is formatted, you can try removing it manually and re-format.
August 27, 20232 yr Author That was the issue, much appreciated. However, what I decided to do was just delete the pool and create a new pool with a different name then delete /mnt/cache/. All is well now.
