Will the disks uuids be the same? And when I have added the old raid5 which contains the data can I add this to the linear array and still have the data or will it be lost? Hmm, probably I have to create a raid5 with the four empty 2 TB disks attached to the LSI. Then: ~$ mdadm -C /dev/md0 -n1 -l linear /dev/md1 Now I copy the content from the old raid5 with the four 1.5 TB disks to the new linear md0.
