What do you expect to see?
A raid1 is a mirror set and to the OS would probably look like a single
drive if it truly is a HW raid

hi, my server hardware supports hardware raid, i installed it
as per normal freebsd 5.3, however i see no difference
in df. its using 2 x 160GB, what do i do during the installation
to enable the raid?

I expect to see data transfer rate increase when you break the mirror.
RAID1 has the higest disk overhead of all RAID configurations and is
very inefficient in that

What happens in terms of performance when a drive in a RAID1 system
fails? Will disk access be slower because it attempts to read/write to
a failed disk or will performance be faster because it doesn't need to
do half the work it usually does? I couldn't really find any online
resources

This tells you that the mediasize of your disk ad0 is smaller than the
mediasize of your mirror on ad2. In simple words, disk ad0 seems to be

Got a live system I'm trying to setup RAID1 on, using gmirror. This is my first
attempt at such a thing.
Two hard-disks: ad0 has a UFS2+softupdates formatted / partition and a swap
partition. ad2 is a clean disk.
I've been following the instructions @:
http://people.freebsd.org/~rse/
I have an ICH6 SATA RAID controller that I have set up with atacontrol to
behave as a RAID1 array. The array (ar0) consists of ad4 and ad6. Last
night I started a dump like so:
# dump -0Luaf /dev/da0s1 /
to *hopefully* dump my root filesystem (ar0s1a) to a usb storage device.
Now here is where

Yes, that makes fine sense.
