From: John Levine on 8 Aug 2010 16:25 I'm setting up a new server running 8.1. It's a reasonably fast used HP box with dual CPU, 12G of RAM, and six U320 15Krpm 72G disks. It sits in a data center and does a mix of mail and web stuff with the usual programs, apache and mysql for the web, netqmail+mailfront and dovecot for mail with a lot of glue and procmail. Its predecessor is pretty disk bound when it's busy. I can set up the HP disk controller to make the disks look like separate disks, or make them all into a RAID5 or a combination. The controller RAID works nicely -- fbsd even syslogs the messages when I pull a disk, stick in a new one, and it rebuilds. So what should I use? The easiest is ufs on a controller RAID. Should I just do that? Use ufs with journalling? zfs on top of controller RAID? zfs on individual disks? R's, John

There might be a benefit to using raid controller cache, if your raid controller supports that (you should research this party further; I only have experience with non-raid attached disks and zfs).

Use ufs with journalling? zfs on top of I use UFS2 with softupdates, and I would recommend using it. Recently, UFS2+softupdates has grown a journaling capability in trunk. I'm not sure if it is available with 8.1. -- steve |
