A raid in a raid.

A raid in a raid.

[mullaly]

Hi,

I have a raid array setup with 6 sata drives (500gb) and 4 ide drives
(250gb). My intention was to setup the disks as follows.
Personalities : [raid0] [raid6] [raid5] [raid4]
md2 : active raid6 md1[6](S) md0[7] sda[0] sdf[5] sde[4] sdd[3] sdc[2]
sdb[1]
      2930318976 blocks level 6, 64k chunk, algorithm 2 [8/6] [UUUUUU__]
      [>....................]  recovery =  0.0% (249556/488386496)
finish=880.0min speed=9242K/sec

md1 : active raid0 hdh[0] hdc[1]
      488396928 blocks 64k chunks

md0 : active raid0 hde[0] hdb[1]
      488396928 blocks 64k chunks

unused devices: <none>

All works well until a system reboot. md2 appears to be brought up before
md0 and md1 which causes the raid to start without two of its drives.

Is there anyway to fix this?

How about listing the arrays in proper order in mdadm.conf ?
