Thursday November 18.
- Update and reboot of beehive and euclid nodes (we start the work at 07:00). These are many nodes, and it can take a while before they become available.
hercules and pleiades nodes will also be updated, but time will be decided together with the PRITS and La Palma groups.
Notes:
Unless unexpected things occur, linux workstations will only require a short downtime for a reboot.
Compute nodes require more time, so expect longer downtime. They will become available as the upgrades complete.
