First locate the example config file

slocate raidtab
ususally it's there:
/usr/share/doc/raidtools-/raidtab.sample
then copy this file to /etc directory as raidtab

cp /usr/share/doc/raidtools-/raidtab.sample /etc/raidtab

then start editing this file to suite your needs.

Take raid1 config as example and you can mark or delete all the rest from this file.

if you have IDE disks then change /dev/sda to /dev/hda respectively.

after finishing - issue this command
mkraid /dev/md? -depending on what you have left in your file as /dev/md?

this will start the raid
all you have left is to make the file system before you can mount the RAID

mkfs /dev/md?

and then mount /dev/md? /mnt

Best Regards...

mkfs on the new volume will delete datas on the new volume if any... but you won't loose anything on the original volume you are going to copy...
no worry on that
