Ocfs2 users - Jul 2010 - some beginner questions

Hi,

I'am new to ocfs2 filesystem and I have some questions about it.

I installed three server according to the user guide from 
http://oss.oracle.com/projects/ocfs2/dist/documentation/v1.4/ocfs2-1_4-usersguide.pdf

For every single server I have a working ocfs2 partition
/dev/sdb1 on /mnt/oc1 type ocfs2 (rw,_netdev,heartbeat=local)

As I understand the ocfs2 system I can use now these partition as a 
single data storage. But it doesn't work. When I create a file or 
directory on the ocfs2 partition, it doesn't "appear" on the other
servers.

SERVER01:
server01:~# echo "sdhfksjdhfskhskjgh" >> /mnt/oc1/testfile
server01:~# cat /mnt/oc1/testfile
sdhfksjdhfskhskjgh
server01:~# ls -lh /mnt/oc1/
insgesamt 0
drwxr-xr-x 2 root root 3,9K 13. Jul 16:53 lost+found
-rw-r--r-- 1 root root   19 14. Jul 20:48 testfile


SERVER02
server02:~# ls -lh /mnt/oc1/
insgesamt 0
drwxr-xr-x 2 root root 3,9K 13. Jul 16:34 lost+found


server03 same result

The config file is the same on all three servers. I made it and copied 
it with the gui program on all three servers. So all server have the 
absolutly same file.

What did I miss? Can somebody give me a hint? Or did I misunderstand the 
ocfs2?

thanks
Alexander

ocfs2 is a shared disk cfs. Meaning it expects the disk/vol to be
accessible by all nodes. Using fiber channel, iscsi, etc.

OCFS2 requires shared storage. Is /dev/sdb a shared device?
