I've never seen a filed owned by uid -2 before! I suppose you are using nfs.
what are the mount options (look for the relevant line in the output of
`mount`)? which is your server, and how was it configured?

The script in
http://gerrit.ovirt.org/gitweb?p=vdsm.git;a=blob;f=contrib/nfs-check.py
may help diagnose few nfs-related problems. Once we understand what's wrong with
you setup, we should probabaly update this script.

Dan.
