High Availability - Oracle 9.3.2 Creating an OCFS2 Cluster for HA. To create an OCFS2-based cluster for HA: On the Server Pool Master, format a volume to be an OCFS2 partition with the mkfs.ocfs2 utility. For example, to create an OCFS2 partition with a 4k block size, 4k cluster size, and 16 node slots: # mkfs.ocfs2 -L mylabel -b 4K -C 4K -J size=64M -N 16 /dev/sda1 High availability configurations - IBM Jun 29, 2020 High Availability - JFrog - JFrog Documentation
