No, no. I do have quorum after the reboots. It is courtesy of the 2 cluster nodes casting their quorum votes. However, the qdevice is not casting a vote so I am down to 2 out of 3 nodes. And the qdevice is not part of the cluster. It will never have any resources running on it. Its job is just to vote. -John > > Starting from a situation such as this, your only hope is to rebuilt the > cluster from scratch, IMHO. > > > Antony. > > -- > Police have found a cartoonist dead in his house.
