Hello, first thanks to everyone who helped me in finding the right patch to use the raidtools with 2.2er kernel. This works now. Because I want to create a mirror of a disk that has already a lot of data on it, I'd like to create the mirror without destroying the data on the original disk. Can this be done? Using the old mdutils this was possible with a dd if=sourced of=newdisk and a mkraid -f --only-superblock /etc/raid1.conf Is there a similar way for the new raidtools?
