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 Regards, Eugen Zitat von Tony Liu <tonyliu0592@hotmail.com>:
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?
Thanks! Tony _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
