Hi

Just noticed my Exchange VM is displaying this error "Virtual Machine disks consolidation is needed".

I quickly found the Snapshot > Consolitdate option but this fails with error:

Unable to access file <unspecified filename> since it is locked

What shall I do? The VM is currently working, disks have space, etc.

check my EE Article, is the Exchange Server running on a snapshot currently?

if so you need to *take action*

HOW TO: VMware Snapshots :- Be Patient

1. you could run out of datastore space and the VM would stop and shutdown, causing possible corruption.

2. exchange running on a snapshot disk is not supported (as far as Microsoft states!)

3. performance will be worse on a snapshot disk.

OK - the VM is running a (several) snapshots which it should not be (looks like Veeam is culprit).

How do I consolidate these?

Yes, Veeam will be the culprit.

(when the server is quiet!)

1. Select Snapshot Manager
2. Create Snapshot
3. Pause 60 seconds
4. Delete Snapshot

I tried this already, but I did not wait 60s! so I am doing this now.

I have just configured an alarm at top level to warn on VM running from Snapshot, and this has placed a warning alarm on ALL VM's - I have checked and none of them are actaully running snapshots??

Hmm this did not work - it removed the snapshot but old ones are still there?

Snapshot Alarm, can be a little hit and miss, you may need to change the snapshot disk size amount.

is the VM still running on a snapshot, unsure how to tell, see my EE Article!

otherwise the files can be deleted. (check first!)

Yes, the VM is still running from a snapshot file :(

I have created 2 or 3 "test" snapshots, waited a few mins and hit Delete All but no joy.

can you screenshot the datastore of files and the VM Settings, so I can check the disks

the current disk is not attached to veeam appliance or backup job is running

The disks were still hot-added onto the Veeam VM, now committing :)

As part of your daily admin, you need to check for snapshots!
