I have deleted many snapshots yesterday from non-root btrfs volume using Yast. One was left with number 1772. There are new snapshots created starting with 1,2,3, numbers it looks like snapper lost track about that one snapshot. It is not listed in snapshots anymore and could not be deleted. The directory in .snapshots cannot be deleted too.

Is there any way I can get rid of this snapshot? Using kernel 3.10.4

Here is part of the log file when it happened:

Looks like the directory /home1/.snapshots/1772 exists but the info.xml file inside not.

You can delete the filesystem snapshot with "btrfs subvolume delete /home1/.snapshots/1772/snapshot" (as root).
After that delete the whole /home1/.snapshots/1772 directory with rm or rmdir.

Worked perfectly. Tx! Drive was full with no space left, could not write anything on disk.
