[Jlab-scicomp-briefs] JLab SciComp outage Tuesday June 21 - Intel Lustre upgrade

[Sandy Philpott]

Hello,

The Intel Lustre upgrade is now rescheduled for the upcoming Tuesday June 21 maintenance day.  During the Lustre upgrade, file services will be unavailable for all JLab HPC, USQCD, and ENP compute nodes and the mass storage system. We plan to upgrade all of the servers in one day, but may have to continue into Wednesday June 22 if extra time is needed. Systems will be unavailable starting at 8am Tuesday, and will be restored to service as soon as the upgrades complete.

Please plan for this necessary outage Tuesday to upgrade the Lustre filesystem.

Regards,
Sandy

All,

We have begun restoring systems and services following the Lustre outage.  In the end, we did not upgrade our Lustre 2.5.3 system to Intel Lustre during this outage as planned, because the Intel upgrade process was not successful in our Lustre testbed.  In short, the required CentOS 6.5 to 6.7 upgrade and Intel Lustre install needs additional work before we can upgrade our production systems.

We will continue to work with Intel to finalize the process, and plan to reschedule the upgrade for a later date.

Regards,
Sandy
