Скрипт используя gnop выравнивает диск под 4кб
проверить можно zdb | grep ashift, должно быть 12 а не 9.
Но ...
Мне не нравится следующее.
Когда я создаю GPT, дискам даю метки
Код: Выделить всё
gpart add -t freebsd-zfs -l disk2 $dev2
Как то так:
Код: Выделить всё
zpool status
pool: rpool
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
ada0p2 ONLINE 0 0 0
ada1p2 ONLINE 0 0 0
Код: Выделить всё
zpool status
pool: rpool

config:

rpool ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
disk1 ONLINE 0 0 0
disk2 ONLINE 0 0 0
Как поправить положение, хочется видить диски в пуле по меткам.
Спасибо.
