Hello,
I am new to cluster HA and I am trying to failover a service between two
nodes. I am using heartbeat 2.0.8 on redhat linux (64 bits).
The monitor operation on the resource is not doing failover after
encountering error during monitor operation. It keeps running the script
on the same node and do not fail over to another node.
My requirement is the service (rsc_tt) should be fail over to another
node after the first failure of monitoring operation. The failover
behavior needs to be same for both the nodes.
Please let me know the configuration I need to modify in order to
achieve this.
My ha.cf is as below
#logfacility local7
logfile /var/log/ha-log
debugfile /var/log/ha-debug
debug 1
use_logd off
udpport 694
keepalive 1 # 1 second
deadtime 4
initdead 10
bcast eth0
#serial /dev/ttyS0 #if you use serial
#baud 19200 #if you use serial
node node1 node2
crm yes
auto_failback yes
#apiauth mgmtd uid=root
respawn root /usr/lib64/heartbeat/mgmtd -t
#respawn root /usr/lib/heartbeat/pingd -m 100 -d 5s
My cib.xml is as below.
