I've set up a 2-node Corosync cluster with Master/Slave DRBD, ClusterIP,
a Filesystem resource, and Apache.
Everything works fine except Apache. I can start Apache from the command
line just fine, but when I shut it off on both nodes and then run:
crm resource cleanup WebSite
It fails to start. The Apache error_log on both nodes shows two lines
each time I run cleanup:
[Thu Nov 10 02:37:33 2011] [notice] Apache/2.2.17 (Linux/SUSE)
mod_ssl/2.2.17 OpenSSL/1.0.0c mod_perl/2.0.5 Perl/v5.12.3 configured --
resuming normal operations
[Thu Nov 10 02:37:34 2011] [notice] caught SIGTERM, shutting down
"grep -i apache /var/log/corosync.log" gives no useful info.
Any idea on what command Pacemaker uses to start Apache? As I said, *I*
can start it from the command line no problem, but Pacemaker fails.
Any suggestions on how I should go about troubleshooting this? What I
should be looking at?
My config looks like this:
