[Ocfs2-users] Previously working cluster - now one node cannot connect

[Joseph Qi]

Please check the node config in configfs in each node:
/sys/kernel/config/cluster/<your_cluster_name>/node/

If it is not the same, try to offline the cluster and then online, which
will reload the config from the cluster.conf.
