August 23, 20241 yr I currently have 2x 2TB M.2 cache drives. They are setup with BTRFS mirror. Is it possible to add a third drive to get more usable capacity?
August 23, 20241 yr Community Expert No, it still works as a raid1 type, but it's not as rigid as others, but it guarantees that any block is written to two different devices, so it can use 3 devices, or any number of devices with raid1.
