OEL is, shall we say, very similar to RHEL. RHEL doesn't support
OCFS2, so it does not include that RA. It is ironic that OEL doesn't
change that. In any case, you can get the RA from the upstream source:

What do you mean? What is the "resource agent for using o2cb"? Please explain 
this a bit closer, I am just becoming familiar with all that stuff.

Thanks for any help,

Subject: [ClusterLabs] Bloody Newbie needs help for OCFS2 on
pacemaker+corosync+pcs

Hello everybody,
I am new to pacemaker (and to this list), trying to understand pacemaker. For 
this I created three virtual hosts in my VirtualBox plus four shared disks, 
attached with each of the three nodes.

I installed Oracle Enterprise Linux 7.1, did a "yum update" and got OEL7.2.
Then I created four OCFS2 devices, working fine on all of my three nodes. They 
are started by systemd, using o2cb.service and ocfs2.service and running fine.

Now I have started with learning pacemaker by "Clusters from Scratch" and 
meanwhile I have a virtual IP and a Webserver, this works fine so far.

Next I want to control my OCFS2 devices by pacemaker, not by systemd. I 
searched the net and found some howtos, but they rely on crmsh instead of pcs. 
Most headaches come from DRBD which I don't understand at all. Why the hell 
does it seem that I need DRBD for running OCFS2?

Is there anybody who can explain me how to get that running (after disabling 
o2cb.service & ocfs2.service):

- create a resource which manages and controls o2cb stack
- create another resource which manages OCFS2 mountpoints
- create constraints for the Web Server (all Apache config / content shall be 
copied to one of the OCFS2 filesystems)

The Web Server shall be dependent from availability of a mounted OCFS2 device. 
If it stops working, the Web Server must switch to a node where that mount 
point is OK.

Thanks in advance for any help
