Virtual machines might stop responding during a snapshot removal due to a forced synchronous consolidation between the snapshot disk and the parent disk. This occurs when the virtual machine is running a heavy I/O workload during snapshot consolidation.
To disable synchronous consolidation add the configuration option snapshot.asyncConsolidate.forceSync = "FALSE" to the VMX file.
Am refering to this KB (http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2041338)
*does this setting automatically modified in the patch ?
*can i modify only this setting ?
*when the KB says "Virtual machines might stop responding during a snapshot removal" does that mean the snapshot removal (consolidation) fails
or completes successfully?
Am using a VADP software(Veeam) for replicating my VMs and am doubting this setting might be the cause of troubles.
As stated in the KB, the VM am talking about does come under heavy I/O.
My issue is : The software needs to remove/consolidate the snapshots once the job is completed.this is the normal operation.
When the VM continues to run on snapshot(s) (after the VADP software has requested a snapshot consolidate) this is very bad.
It will eventually fill up all free space due to enourmous snapshot (delta files) growth.
I asked the question above so that I can confirm whether this setting can prevent this issue from happening again
