[Bug 1412438] Re: OCF:pacemaker:o2cb broken in 14.04

[tonyw]

Digging deeper, it seems that the /usr/sbin/ocfs2_controld.pcmk script
was removed upstream (see https://lists.debian.org/debian-
user/2014/06/msg01224.html) due to openais no longer being part of the
system - and oracle have yet to update the ocfs2-tools package to
provide a non-openais version.

/usr/lib/ocf/resource.d/pacemaker/o2cb should probably be removed from
the resource agents.

I am have managed to find what appears to be a workaround

With reference to http://drbd.linbit.com/users-
guide/s-ocfs2-pacemaker.html#s-ocfs2-pacemaker-drbd

The recommended way to configure an ocfs2 resource for pacemaker
management is to use "crm configure" to add the stanzas

primitive p_controld ocf:pacemaker:controld
primitive p_o2cb ocf:ocfs2:o2cb
group g_ocfs2mgmt p_controld p_o2cb
clone cl_ocfs2mgmt g_ocfs2mgmt meta interleave=trueprimitive p_fs_ocfs2 ocf:heartbeat:Filesystem \
  params device="/dev/drbd/by-res/ocfs2/0" directory="/srv/ocfs2" \
         fstype="ocfs2" options="rw,noatime"
clone cl_fs_ocfs2 p_fs_ocfs2

Howevr, this no longer works as the ocf approach is not possible under
Ubuntu 14.04. Using the lsb script appears to be the best way to manage
the resource i.e.

Edit /etc/default/o2cb and set:
O2CB_ENABLED=true
Ensure that o2cb does not start automatically:
sudo update-rc.d o2cb remove

and use crm configure to add somehhing like

primitive p_o2cb lsb:o2cb \
        op monitor interval="10" timeout="30" \
        op start interval="0" timeout="120" \
        op stop interval="0" timeout="120" 
clone cl_ocfs2mgmt p_o2cb \
        meta interleave="true"
primitive p_fs_disk2 ocf:heartbeat:Filesystem \
        params device=""/dev/drbd/by-res/ocfs2/0" directory="/srv/ocfs2" fstype="ocfs2" options="rw,noatime" \
        op monitor timeout="40" interval="20" depth="0"
clone cl_fs_disk2 p_fs_disk2 

However, there is still a further bug to workaround before ocfs2 works
with pacemaker under 14.04. See

Finally with the workaround and the bug fix, it all seems to work...
