I have installed OCFS2 on two nodes SuSE 10.
Seems all works superb and nice from the first sight.
But,
/dev/sda ocfs2 rac1 is not sharing through net (port 7777) with rac0.
On both nodes I have 500Mb /dev/sda disks that are mounted (and are ocfs2).
But they did not share the content with each other (files and folders in
it). So when I am creating the file in one node I am expecting to receive
this file in another node, but it does not appeared. So how to make OCFS
share the same disk between both nodes (?mounted.ocfs2 ?f? ? shows only one
node that handle with this disk
1. Two nodes are connected with interconnect 1Gb cards.
2. netstat on two nodes says that they are listening on 7777
3. I can go with telnet from one node to another on 7777 port.
(connection established and then closing with ^ character ? so that works)
4. Both nodes configured well, see below (there is rac1, - the rac0 has
analogue result)
5. ocfs2console -> configure nodes shows this two nodes + Propagate was
performed + the device is mounted in mounpoin
6. On both nodes I have 500Mb /dev/sda disks that are mounted (and are
ocfs2). But they did not share the content: files and folders in it.So when
I am creating the file in one node I am expecting to receive this file in
another node, but it does not appeared. So how to make OCFS share the same
disk on between both nodes (?mounted.ocfs2 ?f? ? shows only one node that
handle with this disk)

OCFS needs shared storage, your /dev/sda sounds like local storage, not shared.
