我用 ceph 16.2.7 创建了一个集群，并添加了带有集群扩展的 OSD，然后我按照以下步骤从粉碎图中删除了一些 OSD。此外，选项 --all-available-devices 是不受管理的。

在此处输入图像描述 #ceph orch apply osd --all-available-devices --unmanaged=true

    #ceph osd out osd.x
    
    #ceph osd down osd.x
    
    #systemctl stop ceph-d813d6b4-6d3c-11ec-a97e-000c2992a0d6@osd.x.service
    
    #ceph osd crush rm osd.x
    
    #ceph osd rm osd.x
    
    #ceph auth rm osd.x
    
    #cd /var/lib/ceph/d813d6b4-6d3c-11ec-a97e-000c2992a0d6/
    
    #rm osd.x -rf
    # cd /etc/systemd/system/ceph-d813d6b4-6d3c-11ec-a97e-000c2992a0d6.target.wants/
    # rm ceph-d813d6b4-6d3c-11ec-a97e-000c2992a0d6@osd.x.service
    
    #lvremove /dev/ceph-*

但是当我删除与已删除 OSD 相关的 LVM 时。被移除的 OSD 会自动恢复。我不希望这种情况发生。我想在磁盘上手动创建 OSD。谁能给我解释一下？
