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?
Funny you should mention that, because it’s what got me thinking about Ceph in the first place. My other Proxmox node has a 2-drive mirrored ZFS pool, and I went to add a third drive to it and realized that I’d have to move all the data off and rebuild it from scratch, so I started looking for other solutions.
So yeah, I think Ceph can add to an array after-the-fact like that (in addition to the not-waste-capacity-of-random-assorted-disks thing), but I haven’t figured it out enough yet to be sure.

I also totally was mixing up Ceph with ZFS. Linux tech mentions ZFS a lot. That’s the source of most of my RAID knowledge lol
