How To make a Fail Over Cluster (FOC) with RedHat AS-4.

[giri sagar]

Hi There,

SUB: How To make a Fail Over Cluster (FOC) with RedHat AS-4.

I was looking for any kind suggestions, help and guidance.....

I have two high end servers with exactly same Hardware configuration, loaded
with redhat AS-4 (2.6.9-5), both the server A and B (say) having dual xeon
3.6 GHz with 2 GB RAM, 2x147 GB SCSI HDD (mirrored) and etc...

Server-A is up and running with the Grid middle ware applications like
globus, job scheduler and this is the node where the grid users access and
submit their jobs ( The job will get executed on some other available
resources and don't get worried about it; the scheduler will take care of
that... :)

Now for the Server-B; I manually done the partitioning and the mirroring
just like what I had done on the server A. I haven't installed anything on B
but the OS  ( Its fresh ! )


Well, here follows my Questions :-

1. Is there any option to get the exact image of all the stuffs (data,
services, applications, partitioning, "everything" ) what I have it on my
Server-A to the Server-B ?
    a) Ghost    b) Mondo    c) option 'c' is better than all the above.

2. What is the best possible way to make a fail-over cluster between the
server-A and Server-B ? ( The word "fail-over" connotes what I mean and the
requirement)

Any comment on this will be appreciated and Thanks in Advance.

Thank You
