Re: Re: howto boot from the second disk in raid 1

[abdelkader belahcene <abelahcene@gmail.com>]

hi again,

I can boot from the disk 2, if disk 1  is remove logically ( by command  mdadm --manage /dev/md0 --remove /dev/sda1)

If I remove the disk ( physically from the machine), it doen't work.

here the output of mdstat ,  we see that we have just /dev/sdb  it is working,  but the disk one is physically attached. and without removing physically  the disk from the machine.
cat /proc/mdstat
Personalities : [raid1]
md1 : active raid1 sdb2[1]
      58617784 blocks super 1.2 [2/1] [_U]
     
md0 : active raid1 sdb1[1]
      19529656 blocks super 1.2 [2/1] [_U]
     
unused devices: <none>


In the BIOS setup the disk 2 is always declared slave ( may be it simulate and IDE conf). BIOS problem??

any idea

thanks a lot
best regards
