[Ocfs2-users] Unable to access cluster service

[Sunil Mushran]

Well, the format of cluster.conf is fairly strict.
The attributes under the node clause need to be
after a tab. Check the sample file again.

Else, delete the file, unload the modules and fire
up ocfs2console and click on the "Add nodes"
menu-item. When it is done, use "Propagate config"
to propagate the conf to the nodes listed in the file.
