Good Morning,
I currently have 2, 4 bay Media Probox's with 4 drives in each using USB connections. I'm looking to get 2 10 TB drives to replace my aging 2 TB drives. I'm currently using Mergefs to combine the 2 raids together into 1 large drive. I have a few questions on this. I also use duplicati so i do have backups. I tried to look at this Growing a mdadm RAID by replacing disks but that site no longer exists.
Is it as simple as removing the old drives and adding the new?
How do I make sure my files are copied over from the old drives to the new?
