Hi, I've two btrfs filesystems on the same nvme disk / and /home. I'm running fstrim -va as cronjob daily. Today, once fstrim run, apps writing to /home got frozen. Reviewing dmesg show a bug message related to fstrim and btrfs. Rebooting the system- actually forcibly as it couldn't umount /home - and running fstrim manualy on each filesystem; on / it worked fine, on /home I got the same error. Here are the dmesg errors: http://cwillu.com:8080/38.132.118.66/1 Here is the output of btrfs check --readonly with home unmounted: http://cwillu.com:8080/38.132.118.66/2 I've run scrub whith home mounted it said, `Error summary: no errors found` The fstrim kernel error is reproducible on my machine, it occurs every time I run it on my home. So I can test a fix, just hope it doesn't cause data loss.
