Ceph Erasure Coding support

I've read posts about Proxmox not supporting Ceph EC. Last one was dated on May last year. I'd like to ask if, almost one year later, this is still the stance of Proxmox or we can expect EC support in some near future (2021).

I'm considering setting up a separate Ceph cluster (storage only, using Ceph Dashboard) and configure it as a SAN serving my Proxmox cluster (processing only) but this makes my installation more complicated. I really wish I could use Proxmox for all my storate needs.

Best regards,

Pablo

I would also like to use ceph EC. Is there any update on this?
AFAIK there is no plan for this

Can set up ceph manually and just tell Proxmox to use it?
probably, but that would be unsupported from our side, since we do not test that
my guess is that there are some things missing still (AFAICR, ec pools need that the librbd parameter for the data pool is set for qemu...)

Thanks for the response. We are planning major expansions and of course EC would be a better use of storage resources, since there's only about 40% overhead for full redundancy, while replication has at least a 200% overhead.

It would really be good if this could be given some priority.
