"/var" full or ever ran sth. called "bleachbit"?

Comment 2 Christoph Feck 2014-11-16 20:40:31 UTC

Thomas, could be related to openSUSE 13.2 switching to btrfs.

Comment 3 Thomas Lübking 2014-11-16 20:58:26 UTC

Wow, that's many dupes =)

Do you know how SuSE mounts btrfs on /var?
I've a "rw,noatime,ssd,discard,nospace_cache" partition (root, contains /var, no extra partition) and never experienced this crash so far.
