Challenge
Failure to quiesce the system for a snapshot occurs during a VMware replication process.
ESXi logs shows quiesce operation failure:
Solution
There are several replication strategies that you can follow when backing up a VMware machine and running into a failure to quiesce for the snapshot.
A default scenario tries to quiesce and creates a non-quiesced snapshot if the quiesce fails.
Alternatively, there is an option in the ACP to enforce quiesce. In this case, Acura tries to quiesce and fails backup in case quiesce is not happening.
By default the option is off, but if you want to switch on the option, go to ACP, open the Customer page, click the "Manage clouds" button, and select the "Edit" option in the "Actions" column.
After saving, either restart the services on the related deployed replication agent or download the new agent and redeploy it.
