Warning: /dev/md/0 is not on the first disk

[Zeno R.R. Davatz]

Hi List

I am trying to set up my second software raid and encounter following problems:

lilo gives me:
Warning: device outside of RAID set  /dev/hda  0x0300
Warning: using BIOS device code 0x81 for RAID boot blocks
Warning: /dev/md/0 is not on the first disk
Fatal: map file must be on the boot RAID partition

My lilo.conf is:

boot=/dev/md/0
raid-extra-boot="/dev/hdc,/dev/hda"

root=/dev/md/1

append="md=0,/dev/hdc3,/dev/hda3"

cat /proc/mdstat gives me:
md0 : active raid1 ide/host1/bus0/target0/lun0/part1[0]
      97664 blocks [2/1] [U_]
       
md1 : active raid1 ide/host1/bus0/target0/lun0/part3[0]
      76126592 blocks [2/1] [U_]

My /etc/raidtab is:
raiddev /dev/md/0

Thanks in advance for any help and hints.

Software raid hot-swappable?

[Donghui Wen]

Hi,
    I have a small question: If linux software raid hot-swappable?
Do I need to partition the new harddrive first, or I just need to plugin the
new one, and the md will partition it for me?

Thanks!
