RE: [Linux-cluster] Want to Setup NFS with redhat Cluster??



Thanks for the Entire Movie. But Few doubts on mind and want your
suggestions.

I have two nodes A and B That's fine.
C is not a cluster node.

As per the project requirement C has to be always be NFS mounted to A.
When A's application goes down, NFS service wont be able to failover as
lots of users are still mounted and accessing from node c to node A
through NFS.I could see there is one command called umount -a but don't
find it efficient.

How can I achieve that?

Greetings,

	Can anyone Help me in setting up NFS with Red Hat Cluster?

	I still don't understand what is NFS Mount, NFS Client and NFS
Exports?


OK Let us say you have 3 machines A, B, C.

A, B are Cluster nodes.

C is a machine which has to make available the data on its local hard
disks to who ever wants it using NFS protocol. 
This data is available in file format which are stored under directories
say /XXX, /YYY, /ZZZ

Now our friends A & B -- the cluster members -- wants to access data
under /XXX located in C. They are not interested in /YYY and /ZZZ

Now let us bring another player in this love triangle -- a laptop called
as GADDI which wants the /ZZZ available on the NFS server C.


In this Scenario, A and B are NFS clients.

Our GADDI too is an NFS client.

C is the NFS Server. /XXX, /YYY and /ZZZ are NFS exports.

When A and/or B mounts C:/XXX on a local mount point, say /NFSXXX, it is
called and NFS mount

Now the /YYY as yet unused. (like scripts in the whole bollywood
movie....)

:-)


Having explained that can you please rephrase your movie.. err..
scenario again please using the above analogies
