After doing some research I *think* I need to specify a replicated (as opposed to erasure-coded) pool for my_pool's metadata (eg 'my_pool_metadata'), and thus use the command:

```

rbd create -s 1T --data-pool my_pool my_pool_metadata/my_data

```

First Question: Is this correct?

Yes, as explained here https://docs.ceph.com/en/latest/rados/operations/erasure-code/#erasure-codin... I don't know what the qemu equivalent is though. Cheers -- Loïc Dachary, Artisan Logiciel Libre
