Thank you Mart! Pipe is indeed easier. I found this blog. Will give it a try. https://machinenix.com/ceph/how-to-export-a-ceph-rbd-image-from-one-cluster-to-another-without-using-a-bridge-server Tony ________________________________________ From: Mart van Santen <mart@xxxxxxxxxxxx> Sent: April 21, 2022 08:52 PM To: Tony Liu Cc: ceph-users@xxxxxxx; dev@xxxxxxx Subject: Re: [ceph-users] the easiest way to copy image to another cluster Hi Tony, Have a look at rbd export and rbd import, they dump the image to a file or stdout. You can pipe the rbd export directly into an rbd import assuming you have a host which has access to both ceph clusters. Hope this helps! Mart
