How do you put a cluster disk in maintenance mode in Windows Server 2012 R2?

Question

Background: I have created a test 2-node Server 2012 R2 cluster, with an iSCSI cluster disk. I want to format a new partition on the disk. When I try to format the new partition, it says the disk must be in cluster maintenance mode.

I cannot find any option in the Failover Cluster Manager GUI to put a cluster disk into maintenance mode.

I have tried using PowerShell, running Suspend-ClusterResource -Name "<cluster disk name", but get the error message "The cluster request is not valid for this object".

Solution 1

In failover cluster manager, go to your cluster-Storage-Disks . Right click the disk on the right pane and choose More actions-Turn on maintenance mode.

Solution 2

First install the update mentioned here then I would recommend reading up on the actual functions of cluster maintenance in this article.

Good luck!

"Turn on maintenance mode" does not exist under "More Actions": imgur.com/a/nNMcW

I already have KB2919355 installed.

I guess the reason is, that is your witness disk. You can assign another witness or temporarily remove it using "Configure Cluster Quorum Wizard" . If you have even number of nodes, don't forget to add a witness again.
