Failure to Quiesce Virtual Machine error

[jag880]

Hi there.

We have an AF40 setup as our production unit with daily scheduled snapshots. However we are reciving the following error on a nightly basis.

Failed to create vCenter snapshot associated with volume collection VCollection01 schedule Schedule-new for virtual machine Cruncher2 due to failure to quiesce the virtual machine. See vSphere Client to get details on the failure of the snapshot task for this VM.

We have 4 Volumes setup and oriringally had all of the volumens within on Voume Collection to be snapshotted. I have tried breaking up the volumes to multiple collections to be snapshot in a staggered way to see if that would lighten the load and help. Regardless the first volume collection to be snapshot always throughs this error. It is always for a single VM but not alwasy the same VM. I've tried rotating the volumes between being the first one to be snapshot but still receive the error. I can provide more info if needed but was curious if anyone else has experience with this. The majority of our VMs run SQL databases in some form or fashion. Can provide more info if needed. Any help is greatyly appriciated.

Hi Jag8080,

One of the issues with this type of behavior is Windows volume shadow copy services. In other cases it's related to heavy I/O to snapshoted VM and VMTools versions. In your case since the behavior it's across different VMs it's probably related to volume shadow copy services. 

What you need to do is 

1) Ope the Microsoft Management Console (MMC) Disk Management
2) right-click the drive.
3) Select Properties
4) Select the Shadow Copies
5) Select each volume select Disable and Delete any copies
