If you still want to try, just use btrfsck is ok to check if your filesystem is consistent. Or you can remount with option degraded, recovery(maybe help you to make filesystem stable at least).

My other thread a few days ago ("no space left, metadata usage almost full?"), if that's what you're referring to, was about a different filesystem. This one should have enough free space left: # btrfs fi show /mnt/lxc1 Label: lxc1 uuid: 8d08ad6d-4543-4fe5-8b1b-640dc1423d41 Total devices 2 FS bytes used 2.02TiB devid 1 size 2.62TiB used 2.02TiB path /dev/sda5 devid 2 size 2.62TiB used 2.02TiB path /dev/sdb5 Btrfs v3.12 # btrfs fi df /mnt/lxc1 Data, RAID1: total=1.97TiB, used=1.97TiB System, RAID1: total=32.00MiB, used=300.00KiB Metadata, RAID1: total=50.00GiB, used=49.21GiB I've tried using skip_balance - it mounted, but breaks soon after I try to remove any snapshot. -- Tomasz Chmielewski http://wpkg.org ^ permalink raw reply [flat|nested] 12+ messages in thread

To confirm your filesystem status, you can try to run btrfsck to check if there is something wrong. To get a stable fs now, you can try to mount btrfs with option skip_balance and recovery, recovery options try to get a previous good tree root which might help you get a stable fs. > > -- > Tomasz Chmielewski > http://wpkg.org ^ permalink raw reply [flat|nested] 12+ messages in thread

Unfortunately even after using these mount options it breaks as before, as soon as I remove snapshots, or even copy some data in with rsync.
