Hi, we have been running such mixed cluster for almost 2 years. It works without any cephadm related issues. (Even during upgrade form ubuntu 20.04 to 22.04 mixing nodes with docker and podman caused no issues.) Just be careful when upgrading, ceph arm64 containers for 18.2.4 are completely broken. ceph-osd in that containers segvfault and only fix is to upgrade to 19.2.0/19.2.1. https://tracker.ceph.com/issues/67213 Adam W dniu 6.03.2025 o 08:32, Robert Sander pisze:

Hi,

just a quick question:

Is a mixed cluster with nodes running AMD64 and ARM64 CPUs possible?

Is the cephadm orchestrator able to manage such a cluster?

Regards
