RE: md: only binds to one mirror after reboot

thanks a lot,

you told me the rigt way. I had to add the lines "raid1" and "md_mod" to
/etc/mkinitrd/modules. After recreating the initrd image "mkinitrd -o
/boot/initrd.img-2.6.17.8 /lib/modules/2.6.17.8" the server boots into
both raid disk correctly.

isp:~# cat /proc/mdstat
Personalities : [raid1]
md0 : active raid1 hda1[0] hdb1[1]
      154191744 blocks [2/2] [UU]

unused devices: <none>

Pls. find the kernel messages here.

Thanks.

'md' and the drivers for you disks are not compiled into the kernel
but are present as modules in an 'initrd'.
So the kernel parameter or
  md=0,/dev/hda1,/dev/hdb1
is ignored and the code in the inird is completely responsible for
assembling md0.
You have a look at what it does:
  
  mkdir /foo
  mount -t cramfs /initrd.img  /foo
                  ^^^^^^^^^^^

You have to find the initrd that is being used and use that name here.
Then have a look at etc mdadm.conf in /foo.

Once you understand the problem you will need to remake your initrd to
get this right.
