But you sho
But you should be able to clone the mirrored snapshot on the remote
cluster even though it’s not protected, IIRC.
Zitat von Adam Boyhan :
Two separate 4 node clusters with 10 OSD's in each node. Micron 9300
NVMe's are the OSD drives. Heavily based on the Micron/Supermicro
white papers.

When I attempt to protect the snapshot on a remote image, it errors with read
only.
root@Bunkcephmon2:~# rbd snap protect CephTestPool1/vm-100-d
Have you tried just using them?
(RO, if you do RW things might go crazy, would be nice to try though).
You might be able to create a clone too, and I guess worst case just cp/deep
cp.
I'm interested in your findings btw. I'd be greatful if you share them :)
Thanks!
