My ext4 partition is also called /data and I then softlink other directories onto that partition as required. Yes, you can add it at any time - you only need the "mdadm" package, although it's also possible to set up mirroring using LVM, btrfs or ZFS if you prefer. The way I did it is to physically install the new drives, partition them, use mdadm to set up a RAID-1 mirror, and then finally create a filesystem on the mirror volume. In the old days I used to use the device names for the RAID component partitions and the mirror volume, but now I recommend using UUIDs for both to ensure everything will work correctly regardless of any changes to the device names. You can find the instructions with "man mdadm", and that points you to https://raid.wiki.kernel.org/ if you need even more information. Hope that helps!
