我用1mon 1mds 1mgr和15osd创建了一个新的ceph集群。设置完成后，一切都正确，但是pg状态保持小尺寸+对等。所有磁盘都是新安装的独立XFS，大小范围从3TB到4TB，没有分区表。所有osd日志都显示无用。

这是我的ceph -s日志：

  cluster:
    id:     19e50b60-31b0-467a-8ea9-6c37742a1f77
    health: HEALTH_WARN
            Reduced data availability: 8 pgs inactive
            Degraded data redundancy: 8 pgs undersized
            1 monitors have not enabled msgr2

  services:
    mon: 1 daemons,quorum wuminghan-K600-1G (age 25m)
    mgr: wuminghan-K600-1G(active,since 24m)
    osd: 15 osds: 15 up (since 23m),15 in (since 8h)

  data:
    pools:   1 pools,8 pgs
    objects: 0 objects,0 B
    usage:   15 GiB used,135 GiB / 150 GiB avail
    pgs:     100.000% pgs not active
             8 undersized+peered

这是我的ceph.conf：

每一步之后都是手动设置ceph官方文档。以前也尝试过使用ceph-deploy进行安装，但没有成功。

可以成功创建池。但是运行rbd ls或rbd pool init rbd会永远挂起，没有任何输出。
