On Tuesday 18th December, we will be performing an upgrade of our tier2 fileserver. This work will be performed at 16:30 AEST. While we run an Active/Passive configuration on the tier2 fileserver, the time it takes to failover to the backend fileserver may in some instances exceed the timeout of the nfs client and I/O requests may timeout. We encourage users of the tier2 fileserver who experience this, to simply retry shortly after the timeout.
We apologise for any inconvenience this may cause.
UPDATE - 2018-12-18 @ 16:41 - upgrade has been completed
