I run a pair of Debian servers. One is essentially a NAS, and the
other is a backup system. Both have 30TB (soon to be 48TB) arrays. I
am running XFS, rather than ZFS on the RAID arrays. ZFS is definitely
nice, but is not supported directly under Debian. I don't find the
comparative deficencies of XFS vs. ZFS to be an issue. If these were
enterprise systems, I probably would go with ZFS, directly supported or
not. As it is, these systems work just fine for me, and have for well
over a decade. Here is my layout for my main system:

The boot drives are a pair of 128G SSDs with three partitions on each.
Two of the partitions are employed in RAID 1 arrays formatted as ext2
(/boot) and ext4 (/), with the rest employed as swap space. The data
arrays consist of nine 8T unpartitioned hard drives, 8 as members of a
RAID 6 array formatted as XFS and 1 as a hot spare.

Hi! all,
Thought putting an old, retired system to good use would be better than
letting it gather dust in a closet. And by old, I mean OOOOOLD! I
built it 13 years ago. However, it's been upgraded many times since,
and was still my main box running Stretch until last year. Its current
specs: ASRock A770DE+ AM3 MB, AMD Phenom II x4 @ 3.0 GHZ, 8GB DDR2 RAM
(max 16GB), 6 - SATA II & 1 - IDE connections, USB2.0.
The problem I've run into is finding a NAS OS to run on it. They all
seem to require UEFI. which this MB does not support. (I said it was
old.) However, in my search I did come across OpenMediaVault which is
a simple, lightweight NAS OS based on Debian Jessie that will work with
either MBR or UEFI. One nice feature OMV has is it can be installed as
a service on top of any Debian OS. So, I can use something more
contemporary and still supported.
Anyone currently using OpenMediaVault, or have recommendations for
another package, or advice, in general, on homebuilt NAS?
My plan is to use it for backups, Dropbox-like storage, and possibly
home media server.
Thanks
