How to modify the destination pool name in the rbd-mirror configuration?
Hello, everyone. Under normal circumstances, we synchronize from PoolA of ClusterA to PoolA of ClusterB (same pool name), which is also easy to configure. Now the requirements are as follows: ClusterA/Pool synchronizes to BackCluster/PoolA ClusterB/Pool synchronizes to BackCluster/PoolB After reading rbd-mirror and other documents, I did not find the configuration of different pool names.
Hi, I don't think there's a way to achieve that. You could create two separate backup clusters and configure mirroring on both of them. You should already have enough space (enough OSDs) to mirror both pools, so that would work. You can colocate MONs with OSDs so you don't need additional hardware for that.

Hi Eugen Do you mean that it is possible to create multiple clusters on one infrastructure and then perform backups in each cluster? Eugen Block <eblock@nde.ag> 于2024年11月27日周三 14:48写道：

Sure, I haven't done that with rbd-mirror but I don't see a reason why it shouldn't work. You can create different clusters within the same subnet, you just have to pay attention to the correct configs etc. Each cluster has its own UUID and separate MONs, it should just work. If not, let us know. ;-) Zitat von David Yang <gmydw1118@gmail.com>:

Thanks, Eugen I'll look into how to do this. Eugen Block <eblock@nde.ag> 于2024年11月27日周三 15:21写道：
