Operations Service Update - Tuesday, December 12 at 13:00 UTC

The GOC will upgrade the following services beginning Tuesday, December 12 at 13:00 UTC. The GOC reserves 8 hours in the unlikely event unexpected problems are encountered.

  * Update cvmfs software on oasis and oasis-replica to the latest versions.
  * Rebuild oasis.opensciencegrid.org cvmfs repo from staged files in order to clean out unchunked large files.  This also removes subdirectories whose staged files had been removed: belle, gm2, lbne, icecube, and uc3.
  * Reinstall oasis-login from scratch in order to test that the reinstall process can be done cleanly, including installing the ouser.mis cron job.
  * Set atlas-nightlies.cern.ch repo to use CERN stratum 1 instead of stratum 0.
  * Other minor improvements to scripts on oasis and oasis-replica.

All Services
  * Operating system updates, reboots will be required. The usual HA mechanisms will be used, but some services will experience brief outages.
