Open Stack

Found a way to import volume [1]. Will validate it.
Keep looking into object store multi-site vs. RBD mirror for replicating volumes
between sites. Any comments is welcome.

Thanks!

Subject: [ceph-users] [cinder-backup][ceph] replicate volume between sites

Hi,

I have two sites with OpenStack Victoria deployed by Kolla and Ceph Octopus
deployed by cephadm. As what I know, either Swift (implemented by RADOSGW)
or RBD is supported to be the backend of cinder-backup. My intention is to use
one of those option to replicate Cinder volume from one site to another, based
on RADOSGW multi-site support or RBD mirroring. I wonder if anyone has done
this and could share some opinions, like pros, cons, which way is better for
which case?

One specific thing I am not clear is that, how to import RBD volume into Cinder
when it gets to another site. There used to be a way, but it's replicated.

Any comments is appreciated.

Thanks!
Tony
