Ceph 集群提示池未启用应用程序告警

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
    usage:   876 MiB used, 599 GiB / 600 GiB avail
    pgs:     33 active+clean

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 <pool-name> <app-name>', where <app-name> 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
