This is based on dump_mmp() in debugfs.c.<br/> We added checking recent MMP updates and printed out updated nodename.<br/> This helps the lustre does failover. It prevents both servers issue STONITH at same time when the heartbeat's interlink connection lost. It's kind of idea of quorum disk for the HA clustering. </p> Lustre, failover, pacemaker/corosync LU-2465
