Jeff:
xfs is an excellent choice but it is imperative to understand the
tradeoffs. Data can easily corrupt in xfs if the SATA RAID not
cleanly unmounted and powered down correctly. Another minor problem
is the limited support by commercial distribution vendors.
For reference, we were using xfs on four 16TB units and never ran
into problems. This infrastructure was used for our D2D backup system.
Cheers,
Matthew

We're setting up a new mailserver with a Gigabyte i-ram drive to
handle the qmail queue, and qmail logs. The i-ram drive uses
standard DDR modules, has a battery backup and is lightning fast -
much faster than solid state drives. We'll use SATA RAID for the
maildirs and remainder of the server.
I'd like to get some input on the best filesystem for the i-ram
drive. EXT3 is out because writes are slowed to the speed of a hard
drive. I'm leaning towards reiserfs or xfs. However, I've read
(wikipedia) that reiserfs is easily corrupted. xfs seems the best.
Anyone have any comments of suggestions.
