OS: CentOS 5.5 heartbeat: heartbeat-3.0.3-2.3.el5 (latest from clusterlabs) pacemaker: pacemaker-1.0.9.1-1.15.el5 (latest from clusterlabs)
If it matters, this cluster is primarily used to run Xen virtual machines (xen-3.0.3-105.el5_5.5 kernel-2.6.18-194.11.1.el5xen latest from CentOS) I have been looking off and on for the source of this problem for quite a while without finding what is causing it. The basic problem is that when I reboot a node in my cluster, it comes back up without its static routes. Adding them back in manually works; they stay until the next reboot. These are defined in /etc/sysconfig/static-routes and are added by the network service at boot time. I have been able to pretty much rule out the boot process itself as the source of the problem. I added a "netstat -r -n > /tmp/static-routes" command to the rc.local file which is the very last thing run at boot time and the routes are there. I have also tried putting nodes into standby (crm node standby) and back online, and the routes stay there through that. But once I log in after a reboot, the static routes are gone and I have to manually re-add them. I can probably work around this using a hideous kludge like having the rc.local file run a background job that sleeps for a couple of minutes, then adds the routes, but that doesn't really fix the issue and isn't guaranteed to work reliably (obviously high reliability is important or I wouldn't be using HA in the first place). Has anyone ever seen this before or have any clue where I can look to troubleshoot this?
