Hello Dominik, Can you please provide more information regarding the version of software been tried. We can think of one alternative of node level overrides. Something similar to below: data: values: conf: overrides: ceph_clcp-tenant-ceph-osd-sdd: hosts: - name: node1 conf: storage: osd: - data: type: block-logical location: /dev/sdc journal: type: block-logical location: /dev/sdb - name: node2 conf: storage: osd: - data: type: block-logical location: /dev/sdd journal: type: block-logical location: /dev/sde This will help you to specify the host specific aliases. Please let us know if this helps.

In order to assign the devices correctly, ceph needs to know the host specific addresses. In the hardware profile we defined an alias with the bus address. We only found the use of the alias in the host profile. Can this also be used for ceph or which solution should be preferred here? Thanks and Regards Dominik Bender
