Don- Thank you.  You are correct on both counts.  I've fixed the second item.  Can you give me some ideas on how to fix the first item?

Cluster volume that is shared by each host.

Hi Don -

  I have successfully resized the partition on one of my three hosts.  I restored my VMs from a snapshot and 4 out of 5 are successfully running.  However, the other two hosts still show the old disk at the expanded size.  Do I have to resize it separately on each host?

This is weird.  I resized the volume on host #1 from 6 TB to 3 TB and renamed it.  Hosts #2 and #3 show the old size (6 TB) and the old name.  I rebooted all three hosts.  I start the ASM on one of the hosts and was preparing to take screenshots to show you the difference.  All of the sudden, host #1 has reverted back to the old size and name!  How can this be? 

Here is a screenshot from Failover Cluster Manager.  As you can see, the top line shows the volume TSEV-Data as 2.93 TB.  But the bottom panel shows the same volume as 5.88 TB free out of 6.0 TB.

Don - I'm still struggling with this.  The array side is 3 TB, which is good.  The CSV side shows 6 TB.  If I shrink the CSV side, I lose the VMs and I have to restore from the array side, which then resets the CSV back to 6 TB instead of 3 TB.  It's an endless loop.

I also seem unable to back up the VMs to another location because of VSS problems.  It would seem that all of these things are interrelated?  I would really appreciate your thoughts on how to proceed.
