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?
