Starting on the afternoon of Monday 13th November, we will be performing further NeCTAR OpenStack upgrades, this time on the "nova-compute" services running on the compute nodes in QRIScloud. This is part of the NeCTAR-wide upgrade to the OpenStack "Newton" release.
The upgrades will be done as "rolling upgrades"; i.e. one node at a time, a few compute nodes a day until all have been upgraded. The QRIScloud-HA compute nodes will be done last.
We anticipate that there will be no user-visible impact to QRIScloud users.
In the event that the upgrades run into unexpected problems, NeCTAR Dashboard operations (e.g. launching, snapshotting, rebooting) may stop working for a few minutes for an affected compute node. The instances themselves will be unaffected.
UPDATE: The upgrades happened without incident.
