Starting cluster ocfs2: Failed

Cluster ocfs2 created

o2cb_ctl: Configuration error discovered while populating cluster ocfs2. None of its nodes were considered local. A node is considered local when its node name in the configuration maches this machine's host name.

Stopping cluster ocfs2: OK

 

主机名问题，检查more /etc/ocfs2/cluster.conf以及/etc/hosts文件信息，修改相应的主机名即可，
