I got at work to see the backup still running and having copied about 2Tb in
data for what normally is a 200Gb backup, after a bit of exploring I found a
4Tb log file on a volume that is only 400Gb.
For non nss volumes I know this is usually something with the partition
table after a crash and you can usually just fix it with whatever disk check
tool belongs to the partition type, but with NSS on suse I'm a bit in the
The manual says a verify/rebuild does not fix file system attributes and
there does not seem to be an fsck for nss.

I just deleted the 4tb file but i'd still like to run some kind of fs check
on the volume that can find these kinds of problems.
