RE: RHEL 5.2 -> Sun 2540 Fibre Disk Array



While I've not done it before, I believe it's possible using GFS:

I'm taking RH436 later this month, so hopefully after that I'll have a better idea about how exactly to do it.

Subject: RHEL 5.2 -> Sun 2540 Fibre Disk Array

Hi,

I'd like to get some opinions before I venture on this.  I have a couple
of Sun servers running RHEL 5.2.  They all have fibre cards and are
connected to a Sun 2540 Fibre Disk Array.  I've allocated a chunk of
disk space space on the SAN to be used for /home.

Previously, I would have set up an NFS server and mounted /home from the
other servers.  But now, that everything is connected directly to the
SAN I could mount /home directly without using NFS.

Is this possible or am I still going to need an NFS server to control
access to /home?  The more I think about it, the more it worries me
because /home is a logical volume.  Can I have all the servers accessing
this partion at the same time?  If I can't have all the machines mount
/home directly from the SAN, then that sort of defeats the purpose of
having the SAN for /home, IMO.

What would be the best way for setting this up?
