In future, I'll need to add more 2 disks over RAID1 on my ubuntu server.
I already has a RAID1, but I have more 2 slots in my server and I'll put there more 2 disks to create another RAID1.
I never did it, the only thing I did is simply add normal disks (not in RAID).
My concern is will I need to do something different from the traditional?
Something like, first activate the RAID (as I did when I was installing the ubuntu in the currently RAID1).
Or this will be automatic and I only will need to create the partitions and format them?
