[ceph-users] Re: Upgrade to 15.2.7 fails on mixed x86_64/arm64 cluster

I think you should open an issue on the ceph tracker as it seems the cephadm upgrade workflow doesn't support multi arch container images. docker.io/ceph/ceph:v15.2.7 is a manifest list [1], which depending on the host architecture (x86_64 or ARMv8), will provide you the right container image. docker.io/ceph/ceph manifest references docker.io/ceph/ceph-amd64 and docker.io/ceph/ceph-arm64 container images. So it's expected to have the container image ID 2bc420ddb175 on your x86_64 host and 9a0677fecc08 on ARMv8 host but cephadm doesn't take care of this configuration as the container image ID is compared between two hosts with a different arch [2].
