hi haydar,
my friend i was having the same case : which is a two ml 370 hp proliant
nodes and a shared storage msa500 and the two nodes connected to the shared
by SCSI cable , the problem was with the lock server when implementing the
GFS.
im using RHEL_ES_V3_U4 and a GFS for V3 U4 also, but here in this GFS
release you have to have an odd number of lock server , i mean that when you
have two server so you have to have a three lock server , but in my case i
have used only the first node as lock server and then i reached a poor
redunduncy in the cluster cause i still studying the purchase of a third
server., i heared that there is a release of GFS which is GFS 6.1 working
with RHEL_V4 which will work without the need of the locking service .....
some body correct me if that is not right.
but some body told me that i can use the third lock server as logical not
physical server , he meant that i dont need another HardWare like a server
but my question now is there any body on our list can explain me the use of
the third server as logical way , is it as unix and hp-ux as an area of the
disk used for locking or what?
can we manage one of the two cpu on the server as virtual to get a solution
without another server.
Sorry for the long Email , but we have this last problem.
Regards

Hi Igor,
Thanks for this URL.
My question is: Have I to use 3 nodes to achieve GFS solution?
We have 2 servers HP Proliant 380 G3 (RedHat Advanced Server 2.1) attached
by 2 fiber channels each to the storage area network SAN HP MSA1000 and we
want to install and configure GFS to allow 2 servers to simultaneously
read and write to a single shared file system (Word documents located into
/u04) located on the Storage area network SAN HP MSA1000.
I read the example that you have sent to me and I see 3 nodes, 2 client
nodes share a directory mounted on the 3d server node, but our solution
the directory is located in the SAN.
Have you any explanation or ideas for our request?
Thanks
Haydar

Look at this URL that David suggested to me:
http://sources.redhat.com/cgi-bin/cvsweb.cgi/cluster/doc/min-gfs.txt?rev=1.3&content-type=text/x-cvsweb-markup&cvsroot=cluster
it's pretty good.
