Move an erasure coded RBD image to another pool.

[Caspar Smit <casparsmit@xxxxxxxxxxx>]

Hi all,

I've migrated all of my replicated rbd images to erasure coded images using "rbd copy" with the "--data-pool" parameter.

So i now have a replicated pool with 4K pgs, that is only storing RBD headers and metadata. RBD data is stored on the erasure pool.

Now i would like to move the images (headers and metadata) to another replicated pool with less placement groups.

Is that possible without having to copy the entire contents of the data?

It should only be a matter of moving the header and metadata to another pool isn't it?

Kind regards,
Caspar
