Format the necessary disks as OCFS2 filesystems; OCFS2 cluster makes them available for all the cluster nodes << On only ONE node

mkfs.ocfs2 -b 4K -C 32K -N 4 -L ARCHIVELOGS /dev/xvdh

mkfs.ocfs2 -b 4K -C 32K -N 4 -L GGSHOME /dev/xvdi

Create the necessary mount points (folders) to mount the OFCS2 devices << On BOTH nodes

mkdir /u02mkdir /ggs
