gmirror on slice

[Daniel Gerzo]

Hello people,

 I'm trying to set up a gmirror on two slices, but I am stuck
 somewhere. I am unable to find out what is wrong. Here's what I have
 done so far:

 I have 2 disks in the box. I have created 2 slices on both of them
 (ad{4,6}s1 and ad{4,6}s2) through sysinstall. (btw,
 http://www.freebsd.org/cgi/query-pr.cgi?pr=72895&cat= is really
 annoying, lucky I had a remote console :-))

 Now I want to initialize gmirror on slice 1:

ha-db1# gmirror label -v -b round-robin gm0 /dev/ad4s1
gmirror: Can't store metadata on /dev/ad4s1: Operation not permitted.
ha-db1# sysctl kern.geom.debugflags=16
kern.geom.debugflags: 0 -> 16
ha-db1# gmirror label -v -b round-robin gm0 /dev/ad4s1
gmirror: Can't store metadata on /dev/ad4s1: Operation not permitted.

for additional information, I am including the following:

ha-db1# fdisk -vp ad4
# /dev/ad4
g c1453521 h16 s63
p 1 0xa5 63 72340632
a 1
p 2 0xa5 72340695 1392803370

ha-db1# disklabel /dev/ad4s1
# /dev/ad4s1:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  a:  1048576        0    4.2BSD     2048 16384     8
  b: 25165824  1048576      swap
  c: 72340632        0    unused        0     0         # "raw" part, don't edit
  d: 25165824 26214400    4.2BSD     2048 16384 28528
  e: 20960408 51380224    4.2BSD     2048 16384 28528


 Any ideas will be much appreciated.
