Parameter two_node: 1 is set automatically. At the moment, a quorum is configured and fencing is disabled, but the relocation of resources still provoke a messages in VMware that communication with the LUN has been lost.

The Reset command in VMware was executed as an unexpected shutdown of the node. Resources are moving, but it is the loss of LUNs that is embarrassing
