[ceph-users] cephadm: How to replace failed HDD where DB is on SSD

Hi The server run 15.2.9 and has 15 HDD and 3 SSD. The OSDs was created with this YAML file hdd.yml -------- service_type: osd service_id: hdd placement: host_pattern: 'pech-hd-*' data_devices: rotational: 1 db_devices: rotational: 0 The result was that the 3 SSD is added to 1 VG with 15 LV on it. # vgs | egrep "VG|dbs" VG #PV #LV #SN Attr VSize VFree ceph-block-dbs-563432b7-f52d-4cfe-b952-11542594843b 3 15 0 wz--n- <5.24t 48.00m One of the osd failed and I run rm with replace # ceph orch osd rm 178 --replace and the result is # ceph osd tree | grep "ID|destroyed" ID CLASS WEIGHT TYPE NAME STATUS REWEIGHT PRI-AFF 178 hdd 12.82390 osd.178 destroyed 0 1.00000 But I'm not able to replace the disk with the same YAML file as shown above. # ceph orch apply osd -i hdd.yml --dry-run ################ OSDSPEC PREVIEWS ################ +---------+------+------+------+----+-----+ |SERVICE |NAME |HOST |DATA |DB |WAL | +---------+------+------+------+----+-----+ +---------+------+------+------+----+-----+ I guess this is the wrong way to do it, but I can't find the answer in the documentation.
