Could you elaborate on the fence device. What would suggest using ?

Hi,
You need gfs for the changes to appear on both servers. With GFS, when one
server changes a file, the other server is made aware of the changes. Also
GFS takes care of file locking. Also you need a fencedevice, so the
cluster can shutdown a "defective" server, and make sure it dosn't corrupt
the GFS.
For your current setup:
When you have both servers running, you could mount the ext3 fs on both
servers, but only the server that writes a file, will be aware of it. The
other server will be aware of the new file when you remount the fs.
Hope this helps a bit.
Kind Regards
Kristoffer

Greetings all,
I am an old veteran of HP-UX Service Guard. I am trying to get a NFS linux
Cluster working and need some advise.
I have read the NFS Cookbook from Redhat and have a the following working
2 Node Linux Cluster (RHEL AS 4.0 update 5)
one test disk LVM formated ext3 (have not decided onGFS or not)
Use Vitual IPAddress to access the disks via NFS
When SYSTEMA runs the service and the client machine access the disk and
makes changes. Then I fail over to SYSTEMB these changes made by the
client are not present.
I am runing CLVMD deamon
The LVM disks are mounted on both systems
I have made the following changes to LVM.CONF
(I have tried locking_type = 2 and locking_type = 3) both have he same
results. (as above)
Sorry for my ignorance but can anyone tell me what I am doing
wrong...would GFS solve the syncing problem?
