[Ocfs2-tools-users] heartbeat issue with ocfs2 on debian

[Sunil Mushran]

ocfs2 is for general purpose usage.

The error suggests that the cluster.conf is incorrect. The user's
guide explains how to configure it. The hb slot is the same as the node
number. Ensure both nodes have different node numbers and that
both nodes have the same copy of cluster.conf.

The o2net message indicates that the network config needs to be
looked into. Ensure the ip addresses are correct and that the nodes
can ping each other on that interface.

kernel version?
fs version?
