A new script to be used in Pacemaker to monitor
the Lustre Servers status compatible with ZFS and
LDISKFS based Lustre server installations.

This RA is able to monitor a Lustre Server
using the Pacemaker's clone technology.

pcs resource create [Resource Name] ocf:lustre:healthLUSTRE

--clone

where:
* dampen The time to wait (dampening) further changes occur

This script should be located in /usr/lib/ocf/resource.d/lustre/
of both the Lustre servers with permission 755.
