insertion failed: a problem with the filesystem has been detected: filesystem is probably full

Cause

With the use of automounter, ls -l of an automounted directory is giving the above error. This is a pop-up error message that forces you to press continue. However, the ls -l does not work properly.

Action

Do a df -k to see if the /var directory is completely full. Since the /var/statmon directory contains the locks for NFS, the automount fails if the /var is completely full. After the /var directory is reduced to less than 100% of the automount point, ls -l should work properly.
