在我的本地群集（4个Raspberry PI）中，我尝试配置一个rgw网关。不幸的是，服务会在2分钟后自动消失。

[ceph_deploy.rgw][INFO  ] The Ceph Object Gateway (RGW) is now running on host OSD1 and default port 7480


cephuser@admin:~/mycluster $ ceph -s
  cluster:
    id:     745d44c2-86dd-4b2f-9c9c-ab50160ea353
    health: HEALTH_WARN
            too few PGs per OSD (24 < min 30)

  services:
    mon: 1 daemons,quorum admin
    mgr: admin(active)
    osd: 4 osds: 4 up,4 in
    rgw: 1 daemon active

  data:
    pools:   4 pools,32 pgs
    objects: 80 objects,1.09KiB
    usage:   4.01GiB used,93.6GiB / 97.6GiB avail
    pgs:     32 active+clean

  io:
    client:   5.83KiB/s rd,0B/s wr,7op/s rd,1op/s wr

一分钟后，该服务（rgw：1个守护程序处于活动状态）不再可见：

cephuser@admin:~/mycluster $ ceph -s
  cluster:
    id:     745d44c2-86dd-4b2f-9c9c-ab50160ea353
    health: HEALTH_WARN
            too few PGs per OSD (24 < min 30)

非常感谢您的帮助
