BTIER Resource Agent for Pacemaker

Since BTIER became stable for production environment I wanted it in my clustered SAN, so I wrote an OCF compliant resource agent for managing a BTIER device.

For now is very simple, In future I'm planning to add some other features.

CIB Notation looks like:

primitive BTIER_TIER1 ocf:brick:btier \
params tier_devices="/dev/sda:/dev/sdb" \

device_name="mybtierdev01"
op monitor interval="10s"


I would say thanks to Mark for giving us such a piece of software.
I'm using it in production (with LVM over tiered device) and it works fine.

Download it from my Dropbox and place in /usr/lib/ocf/resource.d/brick (or whatever) directory.
