Ceph » ceph-volume

I tried to deploy ceph octopus (on SLE 15 SP2) on a hardware cluster with the following drive_groups spec:

```
service_type: osd
service_id: drive_group_1
placement:
host_pattern: 'blueshark-[4-7]'
data_devices:
model: 'INTEL SSDSC2BA40'
db_devices:
model: SSDPEDMD800G4
wal_devices:
model: SSDPEDMD800G4
block_wal_size: 21474836480
block_db_size: 21474836480
osds_per_device: 1
```

When calling then:

```
ceph orch apply osd -i drive_groups.yml
```

there is nothing happening. But looking at the mgr container log, it shows:

```
