Well, FYI, the problem *I THINK* was in the fact disks are not equal in
size (ad1 is 3 sectors bigger):

ad0: 38203MB <SAMSUNG SP0411N/TW100-11> [77619/16/63] at ata0-master UDMA100
ad1: 38204MB <SAMSUNG SP0411N/TW100-11> [77622/16/63] at ata0-slave UDMA100

In this case, fresh system was installed onto ad0, gm0 was created on ad1, 
when synchronise with added ad0 (as described in your step-by-step guide).
The first synchronisation process (after addinbg ad0 into gm0) *was ok*,
but after reboot, *I THINK*, gmirror discovered ad0 is less size than
ad1 and refused to include it into gm0. Is this a bug or feature?

The problem was solved by forget'ing gm0, creating gm1 on ad0, whet rebooting and adding
ad1 (wthic is bigger than ad0) into it. Now everything seems to work
ok...
Thanks for the gmirror.
