Cluster error in RHEL 5 servers
Hi Friends,
I am getting the following errors on the cluster at my site. I am using the RHEL 5 cluster suite on for HA of my database and web server. My cluster service at one point of a day restarts automatically. Can you please guide me on this issue. On checking my logs i.e. /var/log/messages it shows me the following info:
Jul 6 18:18:11 DB01 clurgmgrd: [4350]: Failed to ping xxx.xxx.xxx.xxx
Jul 6 18:18:11 DB01 clurgmgrd[4350]: status on ip "xxx.xxx.xxx.xxx" returned 1 (generic error)

Shalom Santosh,
Jul 6 18:18:11 DB01 clurgmgrd: [4350]: Failed to ping xxx.xxx.xxx.xxx

heartbeat failed on the cluster.
Then mysql was stopped on one node and started on a second node.
Check network connectivity:
cables
NIC
switch
switch configuration
logs on the switch if they exist.
Replace or repair accordingly.
If your heartbeat is on a public corporate network and not a private heartbeat network, collision or network congestion could be triggering this.
