 Changes to this message: GPFS unavailable again
2nd Update
 Unfortunately, during Saturday morning GPFS has become unavailable
 again on most nodes of the system.
 Dear users of SuperMUC,
 the reason for the problems with the GPFS filesystem on SuperMUC seem
 to be defective Infiniband hardware component(s), which broke as a
 consequence of the power failure on Sunday, September 23rd.
 Unfortunately, the particular hardware components could not yet be
 identified and we cannot reliably estimate how long the search will
 IBM is still working on the problem.
 We apologize for the inconveniences caused by this failure. We will
 inform you through an update to this announcement as soon as the
 problem is fixed.
