I have a two-node 2008 SP1 Failover Cluster.
I got a problem today:
Drive letter of a cluster volume is lost when I move the cluster disk to another node.
“Cluster Disk 1” had one volume with drive letter “R:”. I assigned another drive letter “F:” to it on node 1.
Then I moved Cluster Disk 1 to node 2.
Its drive letter was gone!
I tried to assign a new drive letter to it. But it was gone every time I moved it to another node.
It never happens before.
Could anyone please tell me why it happens and how to fix it?
By the way, I installed latest windows updates yesterday.
