The KVMGuest resource may remain in the online state even if storage connectivity to the host is lost
When a virtual machine is running on a physical host and loses storage connectivity, the virtual machine goes into the PAUSED state. However, the virtual machine process is still running. The KVMGuest resource monitoring the virtual machine reports the state as ONLINE as the virtual machine process is still running and no failover is initiated. The KVMGuest resource is not aware of the storage situation, and therefore does not take any action.
If this issue occurs, either offline the service group or manually switch the service group. This shuts down the virtual machine and starts the virtual machine on another node.
