squid 19.2.2 cephadm - adding more placement hosts using osd spec yml file
Hi, I am using cephadm and deployed all my OSDs using a spec file I just noticed that osd_ssds has only one placement host instead of all 7 How do I add the other placement hosts ? Re running spec file with "hosts = *" and --dry-run does not indicated it will do anything Many thanks Steven This is the spec file # SSD OSDs service_type: osd service_id: ssd_osds placement: host_pattern: "*" crush_device_class: ssd_class spec: data_devices: rotational: 0 size: '6T:7T' The relevant part of ceph orch ls osd.all-available-devices 4 8m ago 16h * osd.hdd_osds 74 8m ago 16h * osd.nvme_osds 25 8m ago 5w * osd.ssd_osds 84 8m ago 3w ceph-host-1 The exported part of osd.ssd_osds --- service_type: osd service_id: ssd_osds service_name: osd.ssd_osds placement: hosts: - ceph-host-1 spec: crush_device_class: ssd_class data_devices: rotational: 0 size: 6T:7T filter_logic: AND objectstore: bluestore The result of applying the osd-ssd-config.yml ( with --dry-run) WARNING!

If the OSDs already exist, there’s nothing the orchestrator would do, that’s why you don’t see anything in the dry run output. You can apply your change and when one of the hosts will get a new disk or you wipe one, the spec will pick that up. Zitat von Steven Vacaroaia <stef97@gmail.com>:
