I tried the second link, as you suggested. It does not work for me. I 
have to identical disks on /dev/ad10 and /dev/ad8. I have installed 
FreeBSD on /dev/ad10 and I initialized gmirror on that disk. Here is 
what df says:

backupserver# df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/mirror/gm0s1a 4.8G 34M 4.4G 1% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/mirror/gm0s1e 9.7G 12K 8.9G 0% /tmp
/dev/mirror/gm0s1f 115G 261M 106G 0% /usr
/dev/mirror/gm0s1d 9.7G 232K 8.9G 0% /var
backupserver# swapinfo
Device 1K-blocks Used Avail Capacity
/dev/mirror/gm0s1b 5242880 0 5242880 0%
backupserver#


Then I try to add the ad8 device:

backupserver# gmirror insert gm0 /dev/ad8
Provider ad8 too small.
backupserver#

But of course this is not true. ad8 and ad10 are identical 160GB SATA disks.
What am I doing wrong? Please help.

Laszlo
