OK, I created a separate slice for journals at the beginning of
disks (is it supposed to be a little bit faster for journalling
as opposed to the end of disks?). The case is fixed:
-----
ns# fdisk mirror/gm0
******* Working on device /dev/mirror/gm0 *******
parameters extracted from in-core disklabel are:
cylinders=30401 heads=255 sectors/track=63 (16065 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=30401 heads=255 sectors/track=63 (16065 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:

end: cyl 782/ head 254/ sector 63
The data for partition 2 is:

The data for partition 3 is:
