Raid strip with freebsd slices or partitions

Hi, i would like to do a raid strip with freebsd slices or
partitions
and not with a entire disk. For example: I've a two SCSI
drivers with
68Gb. I want to make a two partitions or slices in two
disks, first
with 10G and other with 58Gb, this in two disks, and make a
raid strip
"virtual disk" with 58+58GB = 116 GB, and user
other two partitions
normaly.

-- 
Thanks for all answers

I believe you want to use the GEOM(4) subsystem in general
and the 
gstripe(8) command in particular.  I've only used gmirror(8)
with
entire disks, but I believe you can simply specify a device
name 
corresponding to the slices you want to stripe.

That's correct. Use bsdlabel to divide the disks how you
want them, put your 
normal filesystems on (e.g.) ad0s1a and ad2s1a, and use
ad0s1d and ad2s1d as 
the elements of your gstripe. (e.g. "gstripe label
bigvol ad0s1d ad2s1d").

Or you can divide the disk using fdisk and just use slices
as the elements of 
your gstripe (ad0s2 and ad2s2, for instance). It doesn't
matter what the 
device actually represents; geom can use it.
