Hi,
I have setup a software RAID array in Debian with a 2.4 kernel using mdadm
with this command:
mdadm --create --verbose /dev/md0 --level=0 --raid-devices=2 /dev/hdb3
/dev/hdd2
The two devs are identically sized partitions on two different channels and
two different HDs. This works and tells me that /dev/md0 is up and running.
I mount the device as my home directory with:
mount /dev/md0 /home
Pretty standard so far.
However soon as I reboot and run cat /proc/mdstat
it says I have no md devices. When I run the mdstat and mount commands
everything works fine again.

How do I make this so the raid is setup and mounted whenever the machine is
booted?

thanks in advance,
Craig

hello,

I think you need to change the partition id of your
raid partitions. ID 'fd' as 'Linux raid auto'. So it
would be auto seen by your kernel on startup.

the two partitions are definitely set to FD using cfdisk
any other ideas?

thanks

What does "df -h" show after booting?
It should show something like this.

$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/md0 3.8G 2.7G 1.2G 71% /
/dev/md1 2.3G 557M 1.7G 25% /home
