The dm-* devices are not excluded and will have by-partuuid symlinks etc. This will include devices managed by multipath as well as others. Since this only is used on partitions: # ignore partitions that span the entire disk TEST=="whole_disk", GOTO="persistent_storage_end_two" It may create symlinks for dm-* devices that are unrelated to Ceph and we assume this is going to be ok.
