Hi,

Good news, my colleague Stefan fixed the namespace inconsistencies that I was mentioning: https://github.com/ceph/ceph/pull/48367#event-7561106877

Thanks a lot Ilya for reviewing the PR btw!

Regards,

Lucian

Hi,

rbd namespaces are supported. It's just that "rbd device (un)map" seems to ignore the "--namespace" argument (unmap has the same issue on Linux, we'll have to look into it).

The good news is that the namespace can be specified as part of the image identifier, e.g:

   rbd device map ${rbdPool}/${rbdNamespace}/${rbdImage}

   rbd device unmap ${rbdPool}/${rbdNamespace}/${rbdImage}

messenger v2 is supported as well, for example you can enforce it like so:

    mon host =  v2:${monAddress}

Just one minor implementation detail, the wnbd driver is completely unaware of Ceph, it's just forwarding IO requests to userspace daemons (rbd-wnbd in this case).

Regards,

Lucian

Hi,

We've just published new Pacific and Quincy MSIs, including the ipv6 fix as well as a few others that haven't landed upstream yet. Please let us know how it works.

It works \o/. Just successfully created, mapped, and written to an rbd image in Windows. The driver seems to be using messenger v1 (communicating on port 6789). Is there support for messenger v2?

The "rbd device list" commands shows a "namespace" column. Are rbd namespaces supported (would be awesome)?
