[Pacemaker] DRBD with Pacemaker on CentOs 6.5

[Sihan Goi]

Hi,

That offending line is as follows:
DocumentRoot "/var/www/html"

I'm guessing it needs to be updated to the DRBD block device, but I'm not
sure how to do that, or even what the block device is.

fdisk -l shows the following, which I'm guessing is the block device?
/dev/mapper/vg_node02-drbd--demo

lvs shows the following:
drbd-demo vg_node02 -wi-ao----  1.00g

btw I'm running the commands on node02 (secondary) rather than node01
(primary). It's just a matter of convenience due to the physical location
of the machine. Does it matter?

Thanks.
