## 现象

使用`ceph health`查看集群状态，提示`HEALTH_WARN`，使用`ceph -s`查看详细信息如下：

```bash
[root@ceph12 ~]# ceph -s
  cluster:
    id:     50d4affa-9be6-4e55-9185-59602d63d844
    health: HEALTH_WARN
            1 pool(s) do not have an application enabled
 
  services:
    mon: 3 daemons, quorum ceph12,ceph13,ceph14 (age 3m)
    mgr: ceph12(active, since 2m), standbys: ceph13, ceph14
    osd: 3 osds: 3 up (since 3m), 3 in (since 104m)
    rgw: 3 daemons active (ceph12, ceph13, ceph14)
 
  task status:
 
  data:
    pools:   6 pools, 137 pgs
    objects: 188 objects, 5.9 KiB
    usage:   3.1 GiB used, 1.5 TiB / 1.5 TiB avail
    pgs:     137 active+clean
```

## 解决

运行`ceph health detail`查看详情，提示如下

```bash
[root@ceph12 ~]# 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 'test'
    use 'ceph osd pool application enable <pool-name> <app-name>', where <app-name> is 'cephfs', 'rbd', 'rgw', or freeform for custom applications.
```

根据提示信息，启用相应application后，再次查看集群状态正常

```bash
[root@ceph12 ~]# ceph osd pool application enable test rgw
enabled application 'rgw' on pool 'test'
[root@ceph12 ~]# ceph health detail
HEALTH_OK
```
