[ceph-users] CEPH orch made osd without WAL
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. Sincerely Jan Marek -- Ing.

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.

[ceph-users] Planning cluster
Hello, I have a cluster, which have this configuration: osd pool default size = 3 osd pool default min size = 1 I have 5 monitor nodes and 7 OSD nodes. I have changed a crush map to divide ceph cluster to two datacenters - in the first one will be a part of cluster with 2 copies of data and in the second one will be part of cluster with one copy - only emergency. I still have this cluster in one This cluster have a 1 PiB of raw data capacity, thus it is very expensive add a further 300TB capacity to have 2+2 data redundancy. Will it works? If I turn off the 1/3 location, will it be operational? I believe, it is a better choose, it will. And what if "die" 2/3 location? On this cluster is pool with cephfs - this is a main part of CEPH. Many thanks for your notices. Sincerely Jan Marek -- Ing.
