Nastavitven fajl za mdadm je po defaultu /etc/mdadm.conf:

server1->root root :P cat /etc/mdadm.conf
DEVICE  /dev/hda1 /dev/hde2
ARRAY   /dev/md0  devices=/dev/hda1,/dev/hde2 level=1
server1->root root :P

Sam sem raid delal z direktnim vpisovanjem tja notri.

Lep pozdrav,
Miha

Pozdrav,

že ob inštalaciji Debiana (etch) sem spravil /dev/sda1 in /dev/sdb1 v RAID1 (/dev/md0). Potem sem želel v array dodati še eno particijo, /dev/sdc, kar mi je nekako uspelo (čaral sem z mdadm -G in mdadm -a). Ko se je array rebuildal, sem dobil tole:
lit01s01:~# mdadm -D /dev/md0

Do tu vse lepo in prav. Ampak ob vsakem rebootu, mi mdadm pokaže tole:
lit01s01:~# mdadm -D /dev/md0
/dev/md0:
        Version : 00.90.01

       2       0        0        -      removed

Kaj pri Zevsu moram narediti, da bo /dev/md0 tudi po rebootu sestavljen iz treh naprav? Je kje kakšen konfiguracijski fajl, ki sem ga spregledal?

U.
