Hi, I am investigating a problem that occurred some time ago with a two node cluster. It would appear that rgmanager was unable to stop the application (percona mysql) cleanly according to /var/log/messages. After a while it would appear that rgmanager did start the service again. Does this mean that despite the messages it was indeed able to shut the service down first ?
If a service cannot be stopped cleanly I would have thought that rgmanager does not try and start it again - is this view wrong ? Also the logs show that rgmanager tried to stop the service at 05:06:04 but how do you discover why this action was taken ? I have included an excerpt of /var/log/messages.
