NAS Storage server question

[Coert Waagmeester <lgroups@xxxxxxxxxxxxxxxxx>]

Hello all,


At our office a have a server running 3 Xen domains. Mail server, etc.

I want to make this setup more redundant.

There are a few howtos on the combination of Xen, DRBD, and heartbeat.
That is probably the best way.

Another option I am looking at is a piece of shared storage,
a machine running CentOS with a large software RAID 5 array.

What is the best means of sharing the storage?
I would really like to use a combination of an iSCSI target server, and
GFS or OCFS.

But the iSCSI target server in the CentOS repos is a 'technology
preview'

Have any of you used the iSCSI target server in a production environment
yet?

Is NFS and option?

Kind regards,
Coert Waagmeester
