Hi, can heartbeat detect a network failure? If yes, which options should I use?
my test configuration: - 2 Servers (ubuntu) with heartbeat and drbd. node1: primary node node2: secondary node gateway for both nodes: 10.10.10.1 (pseudo member for this cluster) drbd: configuration as active/passive system # cat /etc/ha.d/haresources node1 IPaddr2::192.168.100.100 drbddisk::r1 Filesystem::/dev/drbd0::/drbd::ext3::defaults # cat /etc/ha.d/ha.cf logfile /var/log/ha.log logfacility local0 keepalive 2 deadtime 20 bcast eth0 node node1 node2 auto_failback on ping 10.10.10.1 # /usr/lib/heartbeat/heartbeat -V 2.1.4 If I shutdown the switch interface from node1, heartbeat on node1 does not unmount the drbd device and does not shutdown the virtual ip. Node1 does not get any answers from node2 and the pseudo member (gateway, 10.10.10.1) and should realize: "I'm cut from the network, so I must stop my heartbeat services." Node2 does not get any heartbeat signal from node1 and mounts the drbd device and starts the virtual IP 192.168.100.100. Node2 does, what it should do. At the moment I don't know, why node1 does not realize the network failure. Has anybody a hint for me?
