Advice: QRIScloud volume storage maintenance schedule: 2017-01


In January, QRIScloud operational staff will be performing required software upgrades to the Ceph servers that provide the QRIScloud / NeCTAR and QRIScloud / RDS volume storage pools.  The schedule is as follows:

  • 2017-01-04 - 09:00 to 17:00 - Upgrading the NeCTAR Ceph cluster from "Hammer" to "Jewel".
  • 2017-01-09 - 09:00 to 17:00 - Upgrading the RDS Ceph cluster from "Firefly" to "Hammer".
  • 2017-01-16 - 09:00 to 17:00 - Upgrading the RDS Ceph cluster from "Hammer" to "Jewel".

This work is not anticipated to lead to significant service interruptions or outages.  However, as with all work of this nature, it is possible for something to go wrong, leading (in a worst-case scenario) to loss of data. 

We therefore advise QRIScloud volume storage users as follows:

  • Make sure that you have the appropriate backup procedures in place for the data in your volumes. 
  • Check that your backups are working properly. In the (unlikely) event of data loss caused by a failed Ceph upgrade, your backups could be the only way to get your data back.
  • If your volume storage dependent systems experience operational problems during the advertised maintenance windows, please let us know promptly.
