I ran into the same situation when I created my first Octopus cluster. After purging everything, I started over and included a “model” instead of “rotational: 0” for data_devices in the spec, and this time it worked fine (it appears both in the output of `orch apply` and `orch ls —export`, as well as in the “devices” of `ceph osd metadata ID` output). Try that instead of “size", maybe? (It helped that all SSDs are the same type in this cluster.) Note: as part of purging my previous attempt, I made sure all traces of LVM were gone from those drives, i.e., lvremove/vgdelete/pgremove. Davor

With db_devices.size, db_devices shows up from "orch ls --export", but no DB device/lvm created for the OSD. Any clues?

Hi Tony.
I assume they used a size constraint instead of rotational. So if all your SSD's are 1TB or less , and all HDD's are more than that you could use:
spec: objectstore: bluestore data_devices: rotational: true filter_logic: AND db_devices: size: ':1TB'
It was usable in my test environment, and seems to work.

Jens

Hi David,
Could you show me an example of OSD service spec YAML to workaround it by specifying size?

Adding ceph-users:
We ran into this same issue, and we used a size specification to workaround for now.

Hi.
I have the same situation. Running 15.2.8 I created a specification that looked just like it. With rotational in the data and non-rotational in the db.
First use applied fine. Afterwards it only uses the hdd, and not the ssd. Also, is there a way to remove an unused osd service. I manages to create osd.all-available-devices, when I tried to stop the autocreation of OSD's. Using ceph orch apply osd --all-available-devices --unmanaged=true
I created the original OSD using the web interface.

How do you manage the db_sizes of your SSDs? Is that managed automatically by ceph-volume? You could try to add another config and see what it does, maybe try to add block_db_size?
Zitat von Tony Liu <tonyliu0592@hotmail.com<mailto:tonyliu0592@hotmail.com>>:
All mon, mgr, crash and osd are upgraded to 15.2.8. It actually fixed another issue (no device listed after adding host). But this issue remains. ``` # cat osd-spec.yaml service_type: osd service_id: osd-spec placement: host_pattern: ceph-osd-[1-3] data_devices: rotational: 1 db_devices: rotational: 0
# ceph orch apply osd -i osd-spec.yaml Scheduled osd.osd-spec update...
# ceph orch ls --service_name osd.osd-spec --export service_type: osd service_id: osd-spec service_name: osd.osd-spec placement: host_pattern: ceph-osd-[1-3] spec: data_devices: rotational: 1 filter_logic: AND objectstore: bluestore ``` db_devices still doesn't show up. Keep scratching my head...
Thanks! Tony

Hi,
I would recommend to update (again), here's my output from a 15.2.8 test cluster:
host1:~ # ceph orch ls --service_name osd.default --export service_type: osd service_id: default service_name: osd.default placement: hosts: - host4 - host3 - host1 - host2 spec: block_db_size: 4G data_devices: rotational: 1 size: '20G:' db_devices: size: '10G:' filter_logic: AND objectstore: bluestore

Hi,
When build cluster Octopus 15.2.5 initially, here is the OSD service spec file applied. ``` service_type: osd service_id: osd-spec placement: host_pattern: ceph-osd-[1-3] data_devices: rotational: 1 db_devices: rotational: 0 ``` After applying it, all HDDs were added and DB of each hdd is created on SSD.
Here is the export of OSD service spec. ``` # ceph orch ls --service_name osd.osd-spec --export service_type: osd service_id: osd-spec service_name: osd.osd-spec placement: host_pattern: ceph-osd-[1-3] spec: data_devices: rotational: 1 filter_logic: AND objectstore: bluestore ``` Why db_devices doesn't show up there?
When I replace a disk recently, when the new disk was installed and zapped, OSD was automatically re-created, but DB was created on HDD, not SSD. I assume this is because of that missing db_devices?
I tried to update service spec, the same result, db_devices doesn't show up when export it.
Is this some known issue or something I am missing?
