My sun server is installed with OS 10 and configured as NIS master server. A nfs file system, which keeps users ' home data, is mounted and shared with option - rq, i.e. checking user account quota. It has been working fine all the time, but recently I found that one user account occupied a lot of hard disk space exceeding his quota but system never reports. On the same file system, orther users accounts are checked with quota. I don't know how the user manage to bypass account quota checking? It is really annoying. Please help.
