Hello Mwoolfso, >From your email "The solution to my particular problem was an improperly >formatted haresources file for Heartbeat.

In my case also, the issue "DRBD device held open" is occurring when I am trying to do failover and stuck in device held open issue. I went through the "/etc/ha.d/haresources" file and found that the "drbddisk::drbd0 LVM::vgdrbd0 Filesystem::/dev/vgdrbd0/mysql::/var/TKLC/elap/drbd/mysql::ext3" is unmounting/detaching a file system. Are you talking about the unmount/detach related to the one highlighted in yellow above. Please provide some thoughts. Cheers!!

The haresources answer was not actually directed to you, but instead belongs to an old thread that happens to have the same subject. The proposed solutions applies to setups with the obsolete heartbeat cluster stack, which you are (hopefully) not using, so this will likely not help your case.
