 Changes to this message: User operation suspended again
Status update (March 13, 17:00) Unfortunately the data corruption
 problem has recurred. We have again suspended user operation. Status
 update (March 13, 16:15) IBM in collaboration with DDN and Mellanox has
 isolated and repaired two technical issues. One of these issues was
 located in the I/O subsystem and has caused data corruption which was
 noticed by GPFS but could not be automatically repaired, leading to
 unavailability of the file system. It is believed that the scope of
 this data corruption was limited to a single file, which was identified
 and removed from the GPFS file system. After successful internal test
 runs the system has been returned to regular user operation.
 Dear users of SuperMUC,
 Due to a problem with the GPFS services access to the file systems WORK
 and SCRATCH is presently disrupted. IBM is attending to the problem,
 and we'll keep you up to date on the status via this document.
 Apologies for any delays in job processing.
