Hi, I attempted doing NFS setup.What I did is
I have one more RHEL Machine where I ran the following command: # vi /etc/exports /datashare *(rw,sync,no_root_squash) #service portmap restart #service nfs restart [root@pe ~]# exportfs /datashare <world> Is it fine? Now, I went to the two nodes and tried : [root@1014236106 ~]# showmount -e
10.14.236.169 Export list for 10.14.236.169: /datashare * [root@1014236106 ~]# The Same Shared Being shown by the second
Cluster Node. Now I opened : #system-config-cluster > Went to
Cluster Configuration > Add New Resource. Now I am confused. There are three Options:
When I
attempted doing NFS Exports , It just says NAME OF EXPORT CONFIGURATION…Whats
That Now? Is it same as entry as /datashare.Or Otherwise Else? I need
to Choose NFS Mount or Exports or NFS Client. Let me
tell you the condition again.I have two Cluster Nodes and Am using NFS as
Alternative Shared Storage. Pls
Help. From:
linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of P, Prakash 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. From:

configure NAS Concept you said earlier. What Should I share actually? Are you Talking about the Script? From: Singh Raina,
Ajeet Hi, I would like to go for iSCSI
Configuration.That sound good.Atleast I will learn something new. Can You provide me with steps by steps
docs. One more thing – What Minimum Size
of Hard Disk we need for That? From: linux-cluster-bounces@xxxxxxxxxx
[mailto:linux-cluster-bounces@xxxxxxxxxx] On
Behalf Of P, Prakash 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 From:
linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of Singh Raina, Ajeet 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?
