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)
