Virtual machine disks consolidation is needed

Veeam Logoby eric » Thu Jan 02, 2014 11:42 pm

Hello All,

I have a machine that is replicating off-site. In vCenter the machine has this notice: Virtual machine disks consolidation is needed

The only snapshot is the Veeam snapshot.

Is this going to be an issue?

Hi Eric, are you talking about the source VM? I believe this message means that there are one or more hidden "worker" snapshots that must be consolidated. So, it is not referring to the Veeam snapshot. Thanks!

[MERGED] virtual machine disks consolidation is needed

Veeam Logoby kellogs » Fri Mar 07, 2014 12:41 pm

Hi,

I have been using VBR 7 Enterprise Plus to replicate VMs and from time to time I am getting this on my source VMs "virtual machine disks consolidation is needed"

All our snapshots are triggered by VBR only.

This is ESXi 5.1U1 hosts running Vmware VSA (2 nodes cluster)

Anyone know why VBR 7 is triggering this error virtual machine disks consolidation is needed?

At the moment we have disabled our replica job.

Please help.

Most likely there're some "hidden" snapshots that are not visible with vSphere Client and should be consolidated.

Hi Foggy,

I am wondering why would VBR created this "hidden" snapshot?

I thought after VBR completed the replication the snapshot supposedly to be removed automatically?

Thanks much

Yes, they are supposed to be deleted. However, occasionally can be left over due to some kind of issues (job crash, locked disk file preventing snapshot commit, etc.).

FYI, we had this issue recently and it was due to high latency on the SAN. Basically the latency was so bad on the storage backend that removing the snapshot was timing out. So that may be something to check as well.

Farshid, thanks for letting us know the reason for this issue in your situation. In order to be notified about this problems in advance, I would recommend installing Veeam ONE free edition to monitor your datastore performance.

[MERGED] Virtual Machine consolidation needed

Veeam Logoby trackstar » Wed Apr 22, 2015 10:37 pm

Hello,



We have a Windows machine 2008 R2 with 1.7TB of total size (made up of 5 disks). In the last few months we have seen this issue often where the snapshot removal process takes forever (after the disk consolidation needed message notification). In snapshot manager, it doesn't show a snapshot but when you browse the directory, there is a orphaned disk. I have opened cases with VMware and Veeam. Veeam support told me the removal process is passed to VMware and it should be their issue. VMware took a few test snapshots for testing and then removed them (delete all). Some snapshots took a long time to remove.

I have been told/read that version 8 of Veeam has an indicator (snapshot hunter) to show any orphaned but would it help in our situation? The removal process is still taking place at the VMware level?

ESXi 5.5

Windows 2008 R2 with Exchange 2010 with 1.7 TB
Veeam 7 patch 4.
Thanks,
TT

If I do an in place upgrade from 7 patch 4, do I have to make any setting change? Also, does version 8 have any other up to date critical patch?

No setting changes are needed.

For patches, see the sticky topic (latest version).
v8 also has an automatic update check.

Thank you. We successfully installed version 8 and patch 1.

Last question. We have days where the job ran over 24 hours (the removal of hidden snapshot). If a job named "X" is currently running and almost reach 24 hours and hasn't finished, would the next scheduled run attempt to start the same job? That would be bad. Just making sure.

No, job cannot be started until it finishes running.

[MERGED] Snapshot Consolidation

Veeam Logoby vipes27 » Mon Jun 06, 2016 3:40 pm

We use Veeam for backups and replication of our VMware environment. Lately, I've been getting a couple of errors on just a couple of our servers, saying that it can't do the backup because it needs snapshot consolidation, but all automatic snapshot consolidation attempts have failed. It says the most likely reason is a virtual disk being locked by some external process. Is it safe to just consolidate the snapshots during production? Thanks.
