Description of problem:
When creating a resource with the RA 'ocf:glusterfs:volume', it doesn't work as expected because it cannot find required infos.

Version-Release number of selected component (if applicable):
glusterfs-resource-agents-3.7.1-1.el7.noarch.rpm

How reproducible:
Everytime

Steps to Reproduce:
1. Create the resource (all prerequisites are OK, ie: the cluster is operational, the FS has been tested without Pacemaker, the resource glustered is created)
pcs resource create gluster_volume ocf:glusterfs:volume volname='gv0' op monitor interval=60s

2. Try to enable/disable/monitor the resource


Actual results:
# pcs status

Additional info:
I patched it localy in the file : /usr/lib/ocf/resource.d/glusterfs/volume

...
volume_getdir() {
    local voldir
    voldir="/var/lib/glusterd/vols/${OCF_RESKEY_volname}"         <===== new value
#    voldir="/etc/glusterd/vols/${OCF_RESKEY_volname}"            <===== old value

    [ -d ${voldir} ] || return 1

    echo "${voldir}"
    return 0
}
