    ocfs2: mount shared volume without ha stack · 912f655d
    Gang He authored
    Usually we create and use a ocfs2 shared volume on the top of ha stack.
    For pcmk based ha stack, which includes DLM, corosync and pacemaker
    services.
    
    The customers complained they could not mount existent ocfs2 volume in
    the single node without ha stack, e.g.  single node backup/restore
    scenario.
    
    Like this case, the customers just want to access the data from the
    existent ocfs2 volume quickly, but do not want to restart or setup ha
    stack.
    
    Then, I'd like to add a mount option "nocluster", if the users use this
    option to mount a ocfs2 shared volume, the whole mount will not depend
    on the ha related services.  the command will mount the existent ocfs2
    volume directly (like local mount), for avoiding setup the ha stack.
