You should create a directory in Spare
server & export that directory as NFS Share. On the cluster nodes there
should be an option to create NFS resource. This will mount the Shared
directory in your cluster node. So you are going to use that exported directory
as Share. Then if you wish you can copy the required scripts into that
directory & run the scripts from there hence it will provide you the
flexibility of failover & failback.

Yes you can do with iSCSI. You need to
install iSCSI software target on the spare RHEL machine & configure the
disk space as virtual SCSI volume.

And on the both machines of the two node
cluster you need to install iSCSI initiators establish iSCSI session with your
target server & u can see the volume on both these servers.

If you are new to iSCSI & feel it
takes more time. You can go for NAS, simply create a NFS share using the spare
RHEL machine & export it to both the nodes of cluster. On Cluster nodes
create some NFS resources for mounting the share automatically.

Regards,

Prakash

Alternative to Shared Storage..

Hello Guys,

Just Now I have been successful in configuring the two Node
Fail-over Cluster. It was tested on RHEL 4.0 U2.Now I have few queries and I know
you people gonna help me out.Since This was small two Node Cluster Setup.I have
few script which I am running on one primary server and on disabling Ethernet
on one , the other is taking responsibility to start the same service plus
rebooting the disabled system

That is working fine.

Now Let me tell you I don’t have Shared Storage.Is there any
alternative for that.

Somewhere I read about iSCSI but donnno whether it will be
helpful.

I have one RHEL System of 40 GB. Can I make it Shared
Storage.

Its Just a matter of Testing a script.

Do Let me Know how gonna it be possible.Or Any Doc Which
Talk about that?
