Lol, you lost me there. I've read up on the various RAID configurations. I've heard about CephFS. I don't know much about it, but I get the sense it's the new kid on the block.
I actually have a RAID question for you. I want to setup a little RAID array starting with 2 mirrored drives and add more drives later. But it seems there is no easy way to migrate RAID versions? Let's say I want to start with 2, then 3, than 4 drives as stuff fills up. I always want some level of redundancy. And I don't want to use any additional drives aside from the 2, 3, then 4 in the array. Is this possible? Either with RAID or with CephFS?
