Versions: whatever's in centos repos.

Any attempts to migrate the services: standby, reboot, etc. result in 
DRBD stuck on unmout. According to lsof it's the kernel keeping the 
filesystem busy. The only difference this time is it happened during yum 
run and scrambled the rpm database on top of everything else.

I've been doing this stuff for quite some time now so please don't 
bother telling me what I did wrong. I wasn't asking.
