snaha o assemble este pred dd zvysku dopadla takto
mdadm --assemble /dev/md4 /dev/mapper/loop0p3 /dev/mapper/loop1p3 /dev/sda3
mdadm: /dev/md4 assembled from 2 drives and 1 spare - not enough to start the array.
stale nerozumiem preco sa sda tvari ako spare a ako ho prinutit byt castou raidu.
mam aj sdb. tam tiez bezi momentalne dd, md raid examine tam vykazuje ale trosku nizsie events.

Ako to postavit na nohy? je moznost presvedcit nejako sda aby sa tvaria ako raid member?
vsetky dalsie invazivnejsie metody ako raid recreation podla parametrov co mam budem robit az po uspesnych zalohach. Stalo sa niekomu nieco poodobne? akym smerom sa vydat prosim Vas?
dakujem
edit: vyzera ze sdb s nizsim event je na tom dost biedne a nebude mozne ho precitat a ak tak s vela vela chybami je mozne to postavit s tymi 3 diskami?
