Hi Lab,


The system is back online, however, one of the file systems required 
maintenance after the reboot.  The NFS server came up before this 
partition was mounted.  This probably invalidated some NFS file 
handles.  I have taken steps to mitigate this situation if it happens in 
the future.  NFS daemon load on the server will be a manual process 
after reboots from now on, ensuring that all partitions mount before NFS 
is started.


Please, check anything you have had running on the compute machines if 
you had anything with open files during the reboot.


If your /auton connected desktop session has hung because of this, you 
will have to restart X-windows or reboot your computer.


Mike
