我在三个节点上安装了 Ceph 集群，测试后需要完全重新安装。似乎在其中一个节点上，一些配置数据仍然保留，Ceph 仍在获取这些数据。
在启动时，Ceph 似乎正在寻找不再存在的旧 OSD。以下是我们的 的内容/var/log/ceph/ceph-volume.log。

为了进行比较，我们已安装的卷（由 找到ceph-volume lvm list）是 -
osd fsid 3038f5ae-c579-410b-bb6d-b3590c2834ff
osd fsid b693f0d5-68de-462e-a1a8-fbdc137f4da4
osd fsid 4639ef09-a958-40f9-86ff-608ac651ca58
osd fsid c4531f50-b192-494d-8e47-533fe780bfa3
您知道这些数据可能来自哪里吗？我该如何删除这些“孤立”卷？
答案1
我设法解决了这个问题。当 Ceph 设置其 OSD 时，它还会创建一个 systemd 服务文件来管理它们。
我必须跳进去/etc/systemd/system/multi-user.target.wants
并删除旧安装留下的每个麻烦的服务 -
