Why under global heartbeat mode, OCFS2 heartbeat regions/volume(s) must be created before o2cb initiation, which is not a prerequisite when using local heartbeat mode (Doc ID 2034854.1)

Last updated on SEPTEMBER 14, 2017

Applies to:

Linux OS - Version 1.6 and later
Linux x86
Linux x86-64

Goal

Under local heartbeat mode, mkfs.ocfs2 could be done later after o2cb initiation.
By contrast, under global heartbeat mode, OCFS2 heartbeat regions/volume(s) must be created before o2cb initiation.

This document explain the reason.
