On Thursday 14/11/2019 (from 9am) the storage cluster operating system 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.
This activity was completed around 8pm Thursday 14/11/2019.
