cephadmブートストラップを使用してcephクラスタをインストールしました。
インベントリを介してディスクを表示できますが、デバイスリストには表示されません。なぜですか？クラスタにディスクを追加するには？

すべてのホストを次に追加したことを確認してください/etc/hosts。
# Ceph
<pulic_network_ip> ceph-1
<pulic_network_ip> ceph-2
<pulic_network_ip> ceph-3
その後、クラスタにceph-nodeを追加する必要があります。
ceph cephadm get-pub-key > ~/ceph.pub
ssh-copy-id -f -i ~/ceph.pub root@<host_ip>
ceph orch host add <host_name> <host_ip>
ceph orch host label add <host_name> <role>
次に、OSDデーモンをディスクに追加します。
ceph orch daemon add osd ceph-1:/dev/sdm
ceph orch daemon add osd ceph-1:/dev/sdn
この方法も利用可能ですが、使用しないことをお勧めします。
ceph orch apply osd --all-available-devices
