  • Permanently unmount the old NFS home filesystem. This will complete the decommissioning of the NFS home filesystem.†
  • Install of Unbound local caching resolver software as recommended by NCSA Security
  • - Remount of remaining NFS exports in readonly mode. Users should migrate any old data off of NFS in preparation for the final NFS decommissioning. NFS is expected to be turned off entirely on July 20, 2017.
    - Upgrade to latest MySQL 5.5 on lsst-db.ncsa.illinois.edu.

Nebula outage

glusterfs crashed due to this bug, so no instances could access their filesystemsAll instances running on NebulaNeeded to reboot the node that systems were mounting from, but took the opportunity to upgrade all gluster clients on other systems while waiting for a reboot. Version 3.10.1 fixes the bug. All instances with errors in their logs were restarted.

Probable cause is that the root file system filled up due to excessive logging

Due to maintenance of cooling infrastructure at NPCF, Blue Waters will down during this period. Cray will also take this maintenance window to perform some system updates at the same time.

Systems that will be down

  • Slurm cluster compute nodes will be powered down for the duration of the outage.

Systems that will remain up

Qserv nodes ( lsst-qserv-* ), SUI nodes ( lsst-sui-* ), Bastion node ( lsst-bastion01 ) should remain online during the outage.  

However, if temperatures in the NPCF rise too high, we will be forced to shut these down as well. I've been told that this is a low-probability scenario and we will be given time to do graceful shutdowns. In the unlikely event that this happens, it will be communicated through the DM Slack channel and also posted here.

All systems normal

NCSA Nebula OutageNCSANebula will take an outage to balance and build a more stable setup for the file system. This will require a pause of all instances, and Horizon being unavailable.

Nebula is back to normal.
