December 18, 20232 yr Hi, I'm having a bit of an issue with my cache SSD. Yesterday night my server went down unexpectedly, when I got it back up again I noticed warnings about BTRFS errors in the logs. After a bit of poking around on the net I came across the `btrfs dev stats /mnt/xxxx` command that tells me I have 4 corruption errors. However, when I try to start a scrub it aborts immediately and tells me there's no errors. I'm a bit lost now, any advice would be greatly appreciated.

December 19, 20232 yr Author Hi, sorry for the delay I had to look up how to run memtest. I created a stick last night and ran it over night, the result this morning was a pass. In terms of backing up and recreating, my pool is a single drive, am I able to btrfs restore, format and reuse or will I need to replace the entire drive?
December 19, 20232 yr Community Expert If the pool still mounts you don't need btrsf restore, just copy everything you can somewhere else.
December 19, 20232 yr Author Ah Ok, that's great and then just do a standard format of the pool drive and copy it back?
December 19, 20232 yr Author I'm having some trouble reformatting the drive. I thought I needed to change the file system type with the array stopped and then restart but having stopped the array I can't change the file system type. I saw something about changing `cacheFsType` in `/config/disk.cfg` but I don't seem to have that key in mine, post was from a while ago though.
