Thank you Anthony! I agree that rbd-mirror is more reliable and manageable and it's not that complicated to user. I will try both and see which works better for me.

I’ve also used rbd-mirror for capacity management, it works well for moving attached as well as unattached images. When using rbd-mirror to move 1-2 images at a time, adjustments to default parameters speeds progress substantially. It’s easy to see when src and dst are synced, then flip primary / secondary, disable mirroring, and rm the src. I’ve used this technique (via an in-house wrapper service) to move hundreds of images. It can handle snaps even, with the right execution. > On Apr 21, 2022, at 8:40 PM, Tony Liu <tonyliu0592@xxxxxxxxxxx> wrote: > > Hi, > > I want to copy an image, which is not being used, to another cluster. > rbd-mirror would do it, but rbd-mirror is designed to handle image > which is being used/updated, to ensure the mirrored image is always > consistent with the source.
