Thanks Rajiv for reverting back to me with a great explanation.
From what I understand:
+Setting "snapshot.asyncConsolidate.forceSync" to FALSE only prevents the VM from being stunned/paused
+ Setting snapshot.asyncConsolidate.forceSync="FALSE" and after 10 asynchronous consolidate if the consolidate is not successfull, the VM will continue to run on the snapshots.
Please advise if I understood correctly.
I can see the snapshot.asyncConsolidate.forceSync="FALSE" setting is more dangerous because it will try to consolidate until it gives up and no longer attempts any consolidation.
Thanks.
