Hi, if you don't specify a different device for WAL it will be automatically colocated on the same device as the DB. So you're good with this configuration. Regards, Eugen Zitat von Jan Marek <jmarek@jcu.cz>:
Hello,
I've tried to add to CEPH cluster OSD node with a 12 rotational disks and 1 NVMe. My YAML was this:
service_type: osd service_id: osd_spec_default service_name: osd.osd_spec_default placement: host_pattern: osd8 spec: block_db_size: 64G data_devices: rotational: 1 db_devices: paths: - /dev/nvme0n1 filter_logic: AND objectstore: bluestore
Now I have 12 OSD with DB on NVMe device, but without WAL. How I can add WAL to this OSD?
NVMe device still have 128GB free place.
Thanks a lot.
