Comprei 2 HD Samsung HD502HI (SATA, 500gb, 5400rpm). Instalei o FreeBSD
8.1 i386 no primeiro e configurei o gmirror no primeiro disco. Ao tentar
inserir o segundo disco no mirror, ele acusou que o provider ad6 era menor:
gmirror insert gm0 /dev/ad6
gmirror: Provider ad6 too small.
Fiquei supreso ao notar que fdisk aponta tamanhos diferentes para os
discos:
fdisk /dev/ad4
******* Working on device /dev/ad4 *******
parameters extracted from in-core disklabel are:
cylinders=969021 heads=16 sectors/track=63 (1008 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=969021 heads=16 sectors/track=63 (1008 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:
sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
start 63, size 976773105 (476939 Meg), flag 80 (active)
beg: cyl 0/ head 1/ sector 1;
end: cyl 1023/ head 15/ sector 63
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>

O primeiro disco (ad4) é um pouco maior que o segundo, como pode ser visto
em cylinders e size. Como é possível?
