Hi,

OK I finally got clone-o2cb started on both nodes and I manually can mount
all my ocfs2 FS on both sides, but just to see, I launch a test which on 
both
nodes in parallel which loops on the mount of all my ocfs2 FS , and then 
umount all of them.
It works on one node, and as soon as I start the test on the second 
node, it works fine
a few seconds and then returns an error on one FS (not necessarily 
always the same) :
mount.ocfs2: Invalid argument while mounting /dev/sdc on /data. Check 
'dmesg' for more information on this error.

so this seems not robust at all ... because I thought ocfs2 was to 
enable these types of manipulations besides IO on
both sides of course.

So my question about Pacemaker and OCFS2 is now :
I don't know the history arount pcmk use with Pacemaker,
but why could we not write a RA ocf script which works with the Stack 
o2cb ?
I mean, having a /etc/ocfs2/cluster.conf well configured, and an ocf script
which start , stop and monitor the service o2cb and the drivers needed etc.

Thanks a lot if someone could give an answer about this.
Alain
