--- Comment #9 from Achim Gratz
That exact version seems to be impossible to find half a year later.
In any case, it's a Tumbleweed install from that date, updated ever since. It should be possible to find out which way the system and snapper was installed by that version and what (if any) changes the updates should have introduced.
I tried that myself with openSUSE 13.2 and the 'snapper delete' command does the ioctl to delete the btrfs subvolume which fails and that is it. Snapper does no umount in that situation (and never a umount of /dev or /proc).
openSUSE 13.2 != Tumbleweed, I'd think.
So I need more information about the "somehow" or exact steps how the reproduce the issue.
1. Boot into a snapshot, rollback. 2. Keep on working from the rollback snapshot, including more snapshots being created. 3. Try to 'snapper rm #-of-rollback. That's it. Since you're left with only the bash builtins at that point there's not a whole lot more I can tell you, sorry. -- You are receiving this mail because: You are on the CC list for the bug.
