Fun fact: all these smart TVs run Linux, which is supposed to facilitate that, but they’re DRM’d to prevent it instead. There are active lawsuits going on about it.

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 have a Proxmox server with a random assortment of hard drives and SSDs of various capacities {8TB, 2TB, 2TB, 240GB, 240GB}. I want to create a CephFS filesystem spanning them, using erasure-coded pools in order to maximize capacity (kind of like RAID 5 except without requiring same-sized drives). How do I configure my CRUSH Map in order to accomplish this?
