I have a RAID1 currently operating on a single hard drive (yes, the mirror is absent). Is it possible to reorganize my system using the following algorithm?
- I set up another single-disk RAID1 (onto another HDD of the same type), partition it and install a new instance of Debian on it.
- I mount the old single-disk RAID1 setup and copy all the data from it to the new RAID.
- I then reformat the old disk and include it into the new RAID setup.
I mostly doubt the second point - how should I do it?
