Volume Collection Leaving VMware Snapshots On VMs

I got several volume collection that does nightly volume snapshots on my vcenter. however this is leaving many snapshots on the vms and they are not getting deleted. why is that?

Hi Tony,

I'm looking at some cases, and there are multiple reasons why this is happening. I recommend you to create a case with support (support@nimblestorage.com) so they can take a peek in your environment to solve this.

Thanks,

Arne

In the event logs for the Host or vCenter, do you see that it attempts to delete/commit the snapshot?

it usually does but someimes it does not. why is NPM not deleting the snapshots afterwards? I am now stuck with a lot of machines with these snapshots leftover.

Did you get a case going with Nimble Support? Definitely get their eyes on this and hopefully they'll have some suggestions on what could be happening.

I've seen this happen with a number of backup products, where they would send the command to VMware to delete a snapshot and for whatever reason it would error out attempting to delete the snap. Afterwards it was just a matter of trying to delete the snapshot again or manually creating a new one and deleting all snaps.

yes we have opened case with nimble. they are saying that we have too many vms on one datastore as a result there is a timeout limit with quiesing the vm. But thge issue it there is no problem with quiescing the vm or taking snapshotso n the vms, it the removal of snapshots that the issue. I actually do not see a task of gettting the snapshot getting removed in vcenter on the vms with the snapshots getting left over.
