Monday 18/12/17 (from 11am for an estimated 4 hours) the storage cluster software underpinning Cinder volumes in the monash-01 availability zone of the Research Cloud will be upgraded.
No outage is required, however there may be minor disruptions to client IO on monash-01 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.
Upgrades completed 18/12/2017 ~6pm.
