Hello guys, I'm trying to use one cluster with 2 nodes, using DRDB 8.x and GFS 1.x on RHEL 5.2 x84_64. The problem is: Then one machine was gone (node2) the node1 stop to work (one simple 'ls -l' on shared mounted point) until the second machine return. I'm using GFS on this way: # gfs_mkfs -t hotsite:gfs-00 -p lock_dlm -j 2 /dev/drbd0 # mount -v /dev/drbd0 /test 'Causing a FAIL on second node on this way: # echo 1 > /proc/sys/kernel/sysrq # echo b > /proc/sysrq-trigger ============================================================================== $ cat /etc/cluster/cluster.conf <?xml version="1.0"?> <cluster name="hotsite" config_version="4"> <cman two_node="1" expected_votes="1"/> <fence_daemon post_join_delay="60"> </fence_daemon> <clusternodes> <clusternode name="drdb_hotsite-1" nodeid="1"> <fence> <method name="single"> <device name="gnbd" ipaddr="192.168.0.3"/> </method> </fence> </clusternode> <clusternode name="drdb_hotsite-2" nodeid="2"> <fence> <method name="single"> <device name="gnbd" ipaddr="192.168.0.3"/> </method> </fence> </clusternode> </clusternodes> <fencedevices> <fencedevice name="manual" agent="fence_manual"/> </fencedevices> </cluster> ============================================================================== Follow the logs: Jun 11 19:59:08 hotsite-bsb-la-1 kernel: drbd0: PingAck did not arrive in time.
