Description Chen Yosef 2020-12-22 14:37:43 UTC

Description of problem:
The installer creates the master VMs without specifying termination grace period, which means using the default 30 seconds. When restarting the VM, the graceful shutdown takes more than that, so after 30 seconds the VM is killed during the shutdown process. This leads in some case (timing related) to XFS metadata corruption that can be recovered only manually.
