OK I would say there's no pressing reason to consider ZFS for this
purpose. You'd save a bit of time in crash recovery with no fsck going on,
and perhaps the checksum mechanism would give some peace of mind - but
really in 15GB silent corruption is a very slow process - now if it were
15TB ...
Thanks.

OTOH you have plenty of memory lying around doing nothing much
(6108M inactive) so you can easily support ZFS if you want to play with
it's features (the smooth integration of volume management and filesystem
is rather cool).
It's hard, nowadays, to buy a server that's too small for our needs. Most
of them are way overspec'd for what this server does. Which is a nice
luxury to have.

It sounds like you have backups or at least some means of restoring
the site in the event of disaster so that's all good.
Yes, daily, and the servers are always configured in RAID1.
If there was a
pressing need to be able to get back up fairly quickly and easily I'd be
suggesting ZFS in RAID1 with a hot swap bay in which a third disc goes,
attached as a third mirror, periodically split it off the mirror take
it off site, and replace it with the one that's been off site.
There's really nothing here that's pushing you in any particular
direction for a filesystem, at 15GB if performance ever becomes a problem
a RAID1 of SSDs with UFS would make it fly probably into the hundreds of
hits per second range.
Thanks for the input, Steve. I appreciate it.
