RAID 1 ... everyime I reboot, /dev/md0 is broken...


Hello all

Just got done adding a 2nd harddisk to my server that already has a huge chunk of date on the first disk.

The idea is to turn the two disks into a RADI 1 array.

I started out by editing my /etc/raidtab file to configure a simple RAID1 device called /dev/md0, mad up from /dev/hda and /dev/hdb.

Next I ran mkraid /dev/md0 and that process took about an hour to finish.

Then I checked with cat /proc/mdstat that my /dev/md0 was working, and it was.

I also checked with fdisk -l /dev/hda and fdisk -l /dev/hdb that both devices apeared to have the same partition scheme, and they did.

So, I assumed that my /dev/md0 is ready to use, but as soon as I rebooted the server, the RAID array didin't initialize and I saw a message during bootup, that somethin regarding RAID was skipped.

Needless to say, as soon as the machine came up again, I ran cat /proc/mdstat only to see that there was no /dev/md0.

My my question is: what must I do to have a RAID 1 array that will be available even after reboot?
What am I missing?
