Reference number: 162839

Summary:

On Thursday June 6th between 00:00 hrs and 07:00 hrs engineers from BIT perform maintenance on the Ceph storage cluster. The cluster will be upgraded with software updates. Also, several optimizations will be applied of which the cluster will benefit from, in terms of stability and performance.

Details:

We do not expect noticeable impact on the cluster during this maintenance. The cluster will be upgraded node by node. When upgrading the nodes we will wait for a fully healthy status of the cluster (Ceph HEALTH_OK), before starting the upgrade of the next node. The cluster has been designed to be upgraded while being in use (live upgrading). Therefore we don't expect any impact on availability or services which make use of the cluster.
