Just on the brink of installing one (Score 1)

We are about install a central machine that
runs NFS, sendmail, DNS, NIS, httpd for internal
use, gnats for around 60 users. Here is the
plan. Two identical machines with 512M ram and
9.0G disks with OS installed. One machine
would be running as NFS server and the other
machine would have all the servers sendmail,
DNS, NIS etc. The NFS server is connected to a diskarray with 7 18.0G disks and a backup
tape autochanger. I want to leave one of the
disks as a hot spare. I would like to write scripts such that if one machine fails, the other can take over by just running a script.

It is the RAID part that is not clear to me. The
last RAID I checked was Veritas on Solaris which
was a major pain in the neck to manage. Don't
know if managing RAID on Linux is any simpler.
I am inclined to wait till RAID becomes a standard
part of Redhat. Until then, I would rather
depend on the tape backups than
Linux RAID support.

I am curious to hear any experiences on people managing large file systems 100G+.

BTW, I haven't still figure how to use our
Exabyte autochanger effectively with a GPLed
backup sofware. Exabyte tech support wasn't very
useful.
