MDADM restart at system boot time

MDADM restart at system boot time

[Paul]

Hi,
 
I hope someone can help.
 
I have manually installed mdadm and now have a working array. I installed mdadm from the tarball, then did 'make install'
 
My problem is after system reboot the array will not start as the daemon is not running, I guess.
 
In order to access my files I have to re-create the array, which it complains about and then re-mount the disks, via the usual 'mount /dev/md0 /data', I know this 'mount' can be done via fstab, but I need the first part to work first.
 
I have the following info in my mdadm.conf file:

DEVICE /dev/hdb1 /dev/hdc1
ARRAY /dev/md0 level=raid1 num-devices=2 UUID=0f0e3d1f:52580ad4:2ef6a2e7:f760e130
        devices=/dev/hdb1,/dev/hdc1
 
I am running Debian 3.1.
 
Thanks
 
Regards

Replace the "DEVICE" entry with:

DEVICE partitions

and add

auto=part

to the end of your ARRAY entry.

Apologies, I was slightly incorrect on the last part.

Replace the "DEVICE" entry with:

DEVICE partitions

and add

auto=part

in place of the "devices=/dev/hdb1,/dev/hdc1" section at
the end of your ARRAY entry.
