Hold on a second here.. why are you using RHEL7 documentation to
configure RHEL6.5? Please don't mix :) there are some differences and we
definitely never tested mixing those up.
There is an example on how to configure gfs2 also in the rhel6.5
pacemaker documentation, using pcs.
I personally never saw this behaviour, so it's entirely possible that
mixing things up will result in unpredictable status.
