Depends on your setup. I’m a btrfs guy, so I’d go with something similar as your other reply. It’s just as easy to remove/replace/add drives. They don’t even have to match in size. Just remember to balance after doing modifications to your array.
It’s extremely simple. Although I prefer ZFS I will give you an example with BTRFS since it’s easier to get going. RAID1 in BTRFS is considered stable (RAID5/6 is not).
sudo mkfs.btrfs -m raid1 -d raid1 /dev/sdx /dev/sdy # Create raid array with BTRFS
sudo mkdir /mnt/storage # Create your mount directory
echo "/dev/sdx /mnt/storage btrfs noatime,compress=zstd 0 0" | sudo tee -a /etc/fstab # Set raid array to mount at boot
sudo mount -t btrfs -o noatime,compress=zstd /dev/sdx /mnt/storage # Manually mount the first time
You would also probably wanna set up a btrfs scrub once per month, either with systemd-timers or cron, whatever you prefer.
