Changes to this message: Update 4th Update (Oct 2, 13:00) The cause of the GPFS failure on Saturday, Sep 29 has been identified as a software problem triggered by data migration to additionally installed disk space. We have decided to continue the data migration in offline mode and expect the system to become fully available again during the afternoon of Wednesday, Oct. 3. Until then, it is possible to log in to the system and perform Loadleveler processing if only data in the HOME directory are accessed. Please also note that the migration system is not affected, and is fully available. We will notify you via this URL when the system is fully available again.
