Hello, When using quorum device, one node is elected "master" and you can see Aug 1 15:36:05 non-master-node qdiskd[8136]: <info> Node 1 is the master on non-master nodes or Aug 1 15:29:47 master-node qdiskd[8044]: <info> Assuming master role on master node. How do you change manually the master node? The only way I found is to do "service qdiskd restart" on the master node but it's not recommended.
