[auton-users] Auton Compute System Downtime Required: Mon Oct 11 04:00 - 08:00 AM

[Michael J. Baysek]

Hi Lab.

Monday, Oct 11, from 04:00 to 08:00 AM the compute system will be
unavailable as I perform maintenance outlined below.

- Re-installation of primary file server (after repairs were made while
   it was off-line)

- Re-installation of LOT2 compute node.

- Installation of new 48 core compute node, LOU1, time permitting.

How this will affect you:

- You will be unable to log in to any compute nodes during this time.

- CVS, Subversion, and MySQL on LYRE will not be available.

- Even though I am switching out the actual file server machine, the system
   is configured in such a way that you will not lose any jobs in progress
   on the compute system.  Any I/O will just hang, until the primary
   server comes online.  Then, the I/O will continue as if nothing ever
   happened.  You won't have to restart any processes... except in the
   case of unanticipated problems, which... are not anticipated, of
   course.  :)
