Primeiro: lembre-se de deixar a nova unidade off-line e certifique-se de que ela não esteja montada ou sendo usada de alguma forma.
Copie as tabelas de partições do disco antigo ada0
para o novo disco ada3
:
% doas gpart backup ada0 | doas gpart restore -F ada3
Agora, ada3
tem as mesmas três partições que ada0
:
% doas gpart show ada3
=> 40 3907029088 ada3 GPT (1.8T)
40 1024 1 freebsd-boot (512K)
1064 984 - free - (492K)
2048 4194304 2 freebsd-swap (2.0G)
4196352 3902832640 3 freebsd-zfs (1.8T)
3907028992 136 - free - (68K)
Remova os metadados antigos do ZFS (observe a partição p3 ):
% doas dd if=/dev/zero of=/dev/ada3p3
Substitua a unidade (observe a partição p3 ):
% doas zpool replace -f zroot 15120424524672854601 /dev/ada3p3
Make sure to wait until resilver is done before rebooting.
If you boot from pool 'zroot', you may need to update
boot code on newly attached disk '/dev/ada3p3'.
Assuming you use GPT partitioning and 'da0' is your new boot disk
you may use the following command:
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da0
Execute o comando mencionado para atualizar as informações de inicialização no novo disco:
% doas gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada3
partcode written to ada3p1
bootcode written to ada3
UUIDs agora são diferentes:
% gpart list ada0 | grep uuid | sort
rawuuid: 7f842536-bcd0-11e8-b271-00259014958c
