Proxmox + RAW EC RBD

[Ashley]

Hello,

So have been testing out raw EC (no change) with CEPHFS and RBD in latest CEPH 12.x release.

Works fine outside of Proxmox, however trying to use a RBD within Proxmox that is created on an EC pool fails.

1/ The RBD image does not show in Proxmox Storage content view however "rbd ls -p cephrbd_metadata" on the node itself shows the image listed.
2/ When trying to boot a VM with the RBD image manually added in the config (due to the RBD image command being different than default Proxmox) it fails with the following : TASK ERROR: unable to parse rbd volume name 'test'

I am thinking it may just be the Proxmox code for checking images in the pool need's to be edited unless their is something deeper causing an issue?

Yeah, I did however unless I missed something seemed they was talking about the general setup of it and not someone attempting to and their findings.

It's probably because the metadata for EC images still needs to be in a replicated pool and Proxmox will need special hooks for this when creating images within the EC RBD pool (just a guess though).
