We have two MS Exchange 2003 clusters, V01 & V02. Each cluster has two nodes and runs Windows 2003. Ent. Ed, with SnapDrive 4.2.1 and SME 3.2. Looking to upgrade soon but not this week...
We use a 2nd server to verify the backups as the server load is high on the Exchange boxes.
The problem is once the verification has finished the flexclone volumes are sometimes left behind. It is normally just the transaction log volume or the database volume. The problem tends to happen on V01 more frequently and we have completed a bare metal re-install of the cluster nodes to try and resolve the issue. – No success.
There are no events on the Filer logs (FAS3070 cluster) and I have not been able to work out a pattern as to when it happens. The work around is to check the filer each morning for the flexclone volumes and offline / delete them.
Does anyone have any ideas to a possible solution. I have heard ESEUTIL throttling can cause this issue but testing has show the problem happens regardless.
Thanks for taking the time to read this and think about the issue. Any help / ideas welcome.
Solved! SEE THE SOLUTION

I'm not sure why SME isn't cleaning up these volumes after the verification is complete. It should delete the works and leave everything clean.
Is there any info in the backup reports for a particular verification job that gives any clue as to what's happening? Or even the event logs on the verification server...those would be helpful to look at as well.
I'll follow up with a few folks to see if this is a known issue or not. I'll post what I find probably next week.

Luck would have it that the issue happened over the weekend.
The SME log is standard expect for this:
Operation completed successfully in 45.735 seconds.
(SnapDrive Error Code: 0xc0040221)
The virtual disk may not be connected, because its mount point cannot be found.

Think I have found the solution.
I was getting alot of Plug & Play errors in the System Log Event, Event ID 257, see Microsoft Article with Hotfix:
Will try this weekend and report back.

Was there a case opened with NGS for this issue? I'm going to bring this up with the engineers and see what we can figure out. But a case number would be good for them to get more info on what's happening.

64bit shouldn't have anything to do with volumes on the storage being left behind.
As soon as I get a case number that I can reference, I can do more investigating and see what I can figure out.
