Hi, I've just followed the steps to build GFS2 volume on the existing RHEL cluster:

pcs resource create dlm ocf:pacemaker:controld op monitor interval=30s on-fail=fence clone interleave=true ordered=true

/sbin/lvmconf --enable-cluster

pcs resource create clvmd ocf:heartbeat:clvm op monitor interval=30s on-fail=fence clone interleave=true ordered=true

pcs constraint order start dlm-clone then clvmd-clone
pcs constraint colocation add clvmd-clone with dlm-clone

pvcreate /dev/sdb
vgcreate -Ay -cy cluster_vg /dev/sdb
lvcreate -L10G -n cluster_lv cluster_vg
mkfs.gfs2 -j2 -p lock_dlm -t iibnpcluster:iibha /dev/cluster_vg/cluster_lv

pcs resource create clusterfs Filesystem device="/dev/cluster_vg/cluster_lv" directory="/var/iibha" fstype="gfs2" "options=noatime" op monitor interval=10s on-fail=fence clone interleave=true

pcs constraint order start clvmd-clone then clusterfs-clone
pcs constraint colocation add clusterfs-clone with clvmd-clone

Now I would like to build new GFS2 volume with /dev/sdc but I am not sure do I need to repeat all the above-mentioned steps to create dlm, clvmd and other resources. Can someone please advise?
