Ocfs2 users - May 2006 - A very basic( theory) question

Hi,

New to this list and BTW great product!


Our setup is:

iSCSI NAS ----> Switch ----> node1     (has a mounted ocfs2 file system)
                                   |-------> node2    (This is the host 
that would share the file system)
                                   |-------> node . .            
                                   |-------> nodeN
      

Node1 has propagated the config and has mounted the ocfs2 file system

df -h :

/dev/sda2              37G  3.3G   34G   9% /
udev                  248M  148K  247M   1% /dev
/dev/sdb1              16G  413M   16G   3% /ocfs2

Now how do I let the other nodes know that a filesytem is avaliable? Or 
do I simply use NFS or iSCSI ? 

Looks like I might be missing something fundemental here since I thought 
the other nodes would become aware of the clusterFS when they loaded the 
kernal modules, etc...

Any help here would be appreciated.

OK so what tools would accomplish this? iSCSI or would NFS work <--- is 
that what you mean by being presented?  What other methods are avaliable?

I seem to have gotten the thoey figured out now. One problem was that 
the san provider said that multiple iscsi initiators on a single target 
would not work. In fact that is exactly how it works.
