The system was a fresh install from openSUSE-Tumbleweed-DVD-x86_64-Snapshot20141112-Media.iso copied to a USB stick. The default settings for a btrfs / were accepted.
That exact version seems to be impossible to find half a year later.
Why the system gets unstable when trying to delete the default snapshot is not clear to me since the kernel ioctl to delete the snapshot simply fails. I will have a closer look when time permits but more information is welcome.
Yes, thankfully the subvolume itself was _not_ deleted. But somehow all filesystems had been unmounted anyway before that was attempted. The system didn't really crash, but with neither /proc nor /dev available you can't do anything useful anymore, not even shut down.
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). So I need more information about the "somehow" or exact steps how the reproduce the issue. -- You are receiving this mail because: You are on the CC list for the bug.
