现象：

  Ceph集群健康状态提示“pool(s) do not have an application enabled”

[root@ceph1 ~]# ceph -s
  cluster:
    id:     65eec0fe-7b48-11ef-8331-0050562d5487
    health: HEALTH_WARN
            1 pool(s) do not have an application enabled

  services:
    mon: 3 daemons, quorum ceph1,ceph3,ceph2 (age 5m)
    mgr: ceph1.rayllt(active, since 18m), standbys: ceph3.vtywtw
    osd: 3 osds: 3 up (since 18m), 3 in (since 3d)

  data:
    pools:   2 pools, 33 pgs
    objects: 13 objects, 3.5 MiB

原因：

  创建池时未配置应用程序导致

解决：

  1、通过命令（ceph health detail）查看提示对应的池名称

[root@ceph1 ~]# ceph health detail
HEALTH_WARN 1 pool(s) do not have an application enabled
[WRN] POOL_APP_NOT_ENABLED: 1 pool(s) do not have an application enabled
    application not enabled on pool 'rbd'
    use 'ceph osd pool application enable  ', where  is 'cephfs', 'rbd', 'rgw', or freeform for custom applications.

  2、通过命令（ceph osd pool application enable PoolName cephfs|rbd|rgw）启用解决

[root@ceph1 ~]# ceph osd pool application enable rbd rbd
enabled application 'rbd' on pool 'rbd'
[root@ceph1 ~]# ceph -s
  cluster:
    id:     65eec0fe-7b48-11ef-8331-0050562d5487
