rayray14 Posted February 27 Share Posted February 27 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 Quote Link to comment
Solution JorgeB Posted February 28 Solution Share Posted February 28 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.

rayray14 Posted February 28 Author Share Posted February 28 Ok, I just tried the repair and got this error: Looks like recreating the pool is the way to go. Quote Link to comment
