Dear support,
We have setup a Redhat cluster with floating IP. The whole cluster is running healthy but occasionally it occurs error messages on "Failed to ping <IP>" and cause node fail-over. It happend from nodea to nodeb and then nodeb to nodea. The network is running healthy. I have searched over Internet and it may relate with the ping program with "segmentation fault". Some workaround is to modify the program of /usr/share/cluster/ip.sh script.
I have modified the script(/usr/share/cluster/ip.sh) so that it always return true on ping. It can solve the problem some period of time(around 1 month) but the problem occurred again in past few weeks. I have inserted some code(like insert date/time info to a log file) to /usr/share/cluster/ip.sh to check for any activities of the script. The strange is that nothing has been output from /usr/share/cluster/ip.sh but the cluster still report "Failed to ping <IP>".
For this ping check activity, which program/script is using so that I can modify?
Can I disable the ping check?
Thanks!
