Hi!
I have some problem to modify a configuration for heartbeat cluster. I
have two nodes and one resource group (mysql_group) like this:
# crm_mon -1
============
Last updated: Fri Jan 28 17:26:15 2011
Current DC: perla-db2 (417fbd34-dd9d-4912-9a65-232a64f52af5)
2 Nodes configured.
1 Resources configured.
============
Node: perla-db1 (1712adcb-9bb6-45ca-ade8-7f20289c820a): online
Node: perla-db2 (417fbd34-dd9d-4912-9a65-232a64f52af5): online
Resource Group: mysql_group
vip (ocf::heartbeat:IPaddr): Started perla-db2
data_dir (ocf::heartbeat:Filesystem): Started perla-db2
mysql (lsb:mysql): Started perla-db2
MySql is configured and works on both nodes.
If the running node is rebooted the cluster works and the service will
switched to the other node. But if I stop MySql, the cluster don't
switch or try to restart it.
How to configure the cluster to check if MySql service is alive?
This is my configuration:
#############
# /etc/ha.d/ha.cf
#############
crm on
logfile /var/log/ha-log
keepalive 2
deadtime 25
initdead 120
udpport 694
mcast eth0 239.0.0.43 694 1 0
auto_failback off
node PERLA-DB1
node PERLA-DB2
