[MLUG] RAID/Volume management opionions sought (was Re: [MLUG - DISCUSSION] HDC)

[Mark Rages <EMAIL:PROTECTED>]

This is a separate question, but I'm replying to this one because it is
slightly related.

I've got a bunch of hard drives I've got to make into a file server.

I've been looking at EVMS (http://evms.sourceforge.net/), LVM 
(http://www.sistina.com/products_lvm.htm), and Linux software RAID5.

Because we are storing movie files, a disk failure isa pain, but not a
catashtrophe. A disk holds several days' work.

I want a system that I can easily add disks to later, that maximizes
the storage space available, and provides enough redundancy that one
hard disk failure is recoverable, and two failures won't take the rest
of the data with them (that *would* be catastrophe).

Is there an economical way to back up this much storage?

Anyone have opinions on EVMS v. LVM? (Last month LVM kernel stuff
was accepted into 2.5, and EVMS announced their next version will be 
userspace only, using the LVM kernel layer.) These systems are proud of
their hot-swap ability, but we don't need 100% uptime, just a measure of
reliability.

I would appreciate any opinions.

Regards,
Mark
