Synopsis: can not connect through ssh to server when /usr is 100% busy

State-Changed-From-To: open->closed
State-Changed-By: jh
State-Changed-When: Fri Dec 9 12:38:52 UTC 2011
State-Changed-Why: 
Unfortunately not much can be done to fix this. FFS snapshots require
suspending all file system operations during the snapshot creation.
Snapshot creation can take considerable long time on large file systems.

ZFS offers quick snapshotting.
