[Pacemaker] Linux HA setup for CentOS 6.5

[Sihan Goi]

Thanks!

OK, so I've followed the DRBD steps in the guide all the way till "cib
commit fs" in Section 7.4, right before "Testing Migration". However, when
I do a crm_mon, I get the following "failed actions".

Seems like the apache Website resource isn't starting up. Apache was
working just fine before I configured DRBD. What did I do wrong?
