Hello,
can someone verify if the following statements are true ?
- It's not possible to simply convert a existing partition with a filesystem on it to a raid1 mirror set.
I believe you're right, but I'm not totally sure on this one. I'd take the second disk, create a new RAID1 with the first drive "missing" on the mdadm --create commandline, copy everything over to it, put grub on it, then test that it boots correctly by pulling the first drive out.
Only once the RAID1 is working (in degraded mode) add the original first drive back in, but booting off the RAID1, then add it to the RAID set to complete the pair. With that process, the question is somewhat moot, although I'm interested in the real answer too
Thats how I'm going to do it althought the version Paul Celemens is mentioning sound very elegant (resizing the fs 128 KB prior to creating the array).
Bye, Robert
