I stopped the cluster completely, modified the config and then started it, but that didn't work either. Same issue. I noticed clurgmgrd wasn't staying running so I then tried this: [r...@omadvnfs01c ~]# clurgmgrd -d -f [7014] notice: Waiting for CMAN to start Then in another window I issued: [r...@omadvnfs01c ~]# cman_tool join Then back in the other window below "[7014] notice: Waiting for CMAN to start", I got: failed acquiring lockspace: Transport endpoint is not connected Locks not working!
