Any to test latest ceph version?

[adamb]

Hey guys I have been doing considerably testing with Ceph Octopus on Proxmox and rbd-mirror snapshots to a remote cluster.

Overall its going pretty well, but I am running into some odd issues with clones on the secondary cluster.

Is there anyway for me to test with the latest ceph pacific builds or latest master on Proxmox? Or would it be best to use something like a vanilla Ubuntu/Debian?

Well, you will need to build it, there doesn't seem to be deb packages for it.

From reading the thread on the ceph list, can you mount the image on the secondary site without the snapshot? And does the content get synced out before the image is unmaped?

Yep I can promote the image on the secondary and the image looks good. Its just the clone of the snapshots on the secondary that I run into the issues.

After or before it has been promoted?

Both. The RBD can be primary or secondary and the RBD snapshots on the secondary are still bad. Snapshots on the primary always look good.

Sadly I don't have hardware to test the setup. AFAICS, it seems possible to do it with journal based rbd-mirror but no mention on snapshot based. Can you try to protect the clone on the primary, so that the protected state is synced as well?

This isn't a procedure issue, its a bug in 15.2.8 from the looks of it. Currently working on compiling the pacific branch from source.
