I said i'll report back....

I finally got OCFS2 working on opensuse-13.1 using
corosync/pacemaker RAs (resource agents).

I uploaded a video to

Be *warned* - it's far too looooooooong!
I did that very late during the night - so at the end
of the video one might hope that i don't fall asleep... :-)

It was my *very first* screen-cast, so my tongue was
not doing what my brain was asking .... so you'll
hear mix-ups of "cluster" vs "cluster nodes" and
"interfaces" vs "cluster"  and so on.

Anyway- my kids said "you should publish it".

If i do any screen-cast again, i'll take more take! :-)

So enjoy. (use a high video resolution)

Cheers, Günter
