I recently installed mdadm an set up a raid1 configuration involving 2 500GIO drives.
Is there a way to backup a RAID configuration somewhere so I could re-load it using a single mdadm command in case I have to re-install my system ?
Let's say my system is installed on some ssd and for some reason I have to re-install it. The thing is, I have this already created RAID1 (Involving those two other disks) .. Is that possible to quickly bring back this RAID1 disk without having to go through all creation steps (wipe disks, create, sync, etc.). In other words, is the RAID lost or mdadm can recover an existing disk ?
