Hello everybody, as ceph newbie I've tried out setting up ceph pacific according to the official documentation: https://docs.ceph.com/en/latest/cephadm/install/ The intention was to setup a single node "cluster" with radosgw to feature local S3 storage. This failed because my ceph "cluster" would not detect OSDs. I started from a Debain 11.1 (bullseye) VM hosted on VMware workstation. Of course I've added some additional disk images to be used as OSDs. These are the steps I've performed: curl --silent --remote-name --location https://github.com/ceph/ceph/raw/pacific/src/cephadm/cephadm chmod +x cephadm ./cephadm add-repo --release pacific ./cephadm install apt install -y cephadm cephadm bootstrap --mon-ip <my_ip> cephadm add-repo --release pacific cephadm install ceph-common ceph orch apply osd --all-available-devices The last command would have no effect. Its sole output is: Scheduled osd.all-available-devices update... Also ceph -s shows that no OSDs were added: cluster: id: 655a7a32-3bbf-11ec-920e-000c29da2e6a health: HEALTH_WARN OSD count 0 < osd_pool_default_size 1 services: mon: 1 daemons, quorum terraformdemo (age 2d) mgr: terraformdemo.aylzbb(active, since 2d) osd: 0 osds: 0 up, 0 in (since 2d) data: pools: 0 pools, 0 pgs objects: 0 objects, 0 B usage: 0 B used, 0 B / 0 B avail pgs: To find out what may be going wrong I've also tried out this: cephadm install ceph-osd ceph-volume inventory This results in a list that makes more sense: Device Path Size rotates available Model name /dev/sdc 20.00 GB True True VMware Virtual S /dev/sde 20.00 GB True True VMware Virtual S /dev/sda 20.00 GB True False VMware Virtual S /dev/sdb 20.00 GB True False VMware Virtual S /dev/sdd 20.00 GB True False VMware Virtual S So how can I convince cephadm to use the available devices?
