Wednesday 11/04/18 (from 10am for an estimated 6 hours) the storage cluster software underpinning Cinder volumes in the monash-02 availability zone of the Research Cloud will be upgraded.
No outage is required, however there may be minor disruptions to client IO on monash-02 volumes. This may manifest as block IO timeouts to instances attempting to write or read volumes.
If you experience any ongoing IO issues please report them to support
All upgrades completed on 11/4 by ~4.30pm.
