February 27, 20242 yr Hello, I woke up to an email from my Unraid server with the subject: "cron for user root /sbin/fstrim -a -v | logger &> /dev/null" and body: fstrim: /etc/libvirt: FITRIM ioctl failed: Input/output error I did a "btrfs check --readonly" on my SSD cache drive and gave me the attached output (btrfs check status (read only).txt) In preparation for a "btrfs checking --repair", I ran the following to create a disk image of the drive in case I ever need to revert back: "sudo dd if=/dev/sde of=/mnt/disk1/ssdimage.img bs=4M status=progress" Before I attempt that repair, is there anything else I should do? btrfs check status (read only).txt
February 28, 20242 yr Community Expert Solution If you have a backup you can try the repair, but btrfs repair is far from optimal, it can't repair a lot of issues, and in some cases it can makes things worse, if that happens recommend recreating the pool and restoring the data from the backup.
February 28, 20242 yr Author Ok, I just tried the repair and got this error: Looks like recreating the pool is the way to go.
