[LUGOS] RAID blues

[Uroš Golja]

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
/dev/md0:
        Version : 00.90.01
  Creation Time : Thu Dec  8 14:59:25 2005
     Raid Level : raid1
     Array Size : 8747264 (8.34 GiB 8.96 GB)
    Device Size : 8747264 (8.34 GiB 8.96 GB)
   Raid Devices : 3
  Total Devices : 3
Preferred Minor : 0
    Persistence : Superblock is persistent

    Number   Major   Minor   RaidDevice State
       0       8        1        0      active sync   /dev/sda1
       1       8       17        1      active sync   /dev/sdb1
       2       8       33        2      active sync   /dev/sdc1
lit01s01:~#

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
  Creation Time : Thu Dec  8 14:59:25 2005

           UUID : 8d412cb7:43025322:cb394580:f2a3163c
         Events : 0.103166

    Number   Major   Minor   RaidDevice State
       0       8        1        0      active sync   /dev/sda1

       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?
