@marcaurele Thats correct. In case of shared/remote storage the same disk
is used to spawn a VM on another host once the VM is successfully fenced. If
the fencer has successfully fenced off a VM, it is assumed that the original VM
is correctly stopped. Now if you are saying that the original VM continues to
run then that means that the specific fencer has bugs and needs fixing. Note
that there are different types of fencer available in cloudstack based on
hypervisor types.
@abhinandanprateek In the scenario you mentioned vmsync won't be able to
mark VM as stopped as the ping command is no longer running as the host is in
alert/down state.
