[Pacemaker] Pacemaker will not mount ocfs2

[Johan Rosing Bergkvist]

Hi
Just an update.
So I upgraded to pacemaker 1.1.6 and tried to configure it all again,
without dlm.
It didn't work, I still got the " OCF_ERR_INSTALLED  so I started looking
through the setup and found that I didn't specify the drbd.conf path.
When  I added that meta and boom, it mounted like a dream.

Wasn't it supposed to return a OCF_ERR_CONFIGURED?

And is that meta even required?

I wonder if I messed something up(that is very likely) or maybe I missed
something.

I'll try to add the dlm today and see if it works.

Cheers.
