To: freebsd-geom at freebsd.org


I've not yet figured out how to set up even on instance of the geom
mirror using either procedure found at:
http://people.freebsd.org/~rse/mirror/.

Here's what I'm trying to do:
I'm upgrading my Samba server by adding some storage. I've got two
250GB drives that I'd like to software raid and one 40 GB system drive
that I'm leaving alone.

When it comes to working with disks, I've always been a sysinstall
kinda guy. Until I started this project o' mine, I'd never even heard
of bsdlabel, geom, etc.

What I'm looking for is some very basic understanding of what steps to
take for a non-system disk geom mirror; what shape my disks need to be
in at the start; what I need to do with bsdlabel, etc.

Here's where I keep failing:
the step where I use bsdlabel. If I do "bsdlabel -w -B
/dev/mirror/gm0s1", I get an error "Geom not found". What should I do
in "bsdlabel -e /dev/mirror/gm0s1"? My other disk looks like this:
# /dev/ad4s1:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  c: 488392002        0    unused        0     0         # "raw" part,
don't edit
  d: 488392002        0    4.2BSD     2048 16384 28552

If I try to make the gm0s1 look like that, I get an error message as well.

Thanks, folks, for the help!!!
