hallo everybody, i have the following hardware which consist of 3 Nodes with the following specs: * 8 HDDs 8TB * 1 SSD 900G * 2 NVME 260G i planned to use the HDDs for the OSDs and the other devices for bluestorage(db) according to the documentation 2% of storage is needed for bluestorage as i am not going to use RGW so i need for each OSD around 160GB of db storage. The ideal setup would be 4 OSDs on the SSD and 2 OSDs on each NVME. But for some reasons using the default config: ``` service_type: osd service_id: osd_spec_a placement: host_pattern: "*" spec: data_devices: rotational: 1 db_devices: rotational: 0 ``` cephadm is assigning 6 OSDs on the NVMEs and 2 on the SSDs. i tries the following config: ``` service_type: osd service_id: osd_spec_a placement: host_pattern: "*" spec: data_devices: paths: - /dev/sdc - /dev/sdd - /dev/sde - /dev/sdf db_devices: model : Micron_ --- service_type: osd service_id: osd_spec_b placement: host_pattern: "*" spec: data_devices: paths: - /dev/sdg - /dev/sdh - /dev/sdi - /dev/sdj db_devices: model : KXG60ZNV256G ``` but `ceph orch apply -i osd.yaml --dry-run` is taking forever and not generating any data. Does anybody have an idea how to setup the filter the right way ? thanks a lot, Ali _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
