錯誤提示

使用 ceph -s 提示叢集狀態 HEALTH_WARN

[root@ceph01 ~]# ceph -s
  cluster:
    id:     b356ff71-d7e6-4bdf-abae-9bbd141567c3
    health: HEALTH_WARN

• clock skew detected on mon.ceph02, mon.ceph03 叢集時間不同步，測試環境忽略，如果是生產環境建議同步叢集時間

解決方法

檢視具體資訊

[root@ceph01 ~]# ceph health detail
HEALTH_WARN application not enabled on 1 pool(s); clock skew detected on mon.ceph02, mon.ceph03
POOL_APP_NOT_ENABLED application not enabled on 1 pool(s)
    application not enabled on pool 'k8s'
    use 'ceph osd pool application enable <pool-name> <app-name>', where <app-name> is 'cephfs', 'rbd', 'rgw', or freeform for custom applications.
MON_CLOCK_SKEW clock skew detected on mon.ceph02, mon.ceph03
    mon.ceph02 addr 10.10.10.52:6789/0 clock skew 0.663051s > max 0.05s (latency 0.00209386s)
    mon.ceph03 addr 10.10.10.53:6789/0 clock skew 0.221461s > max 0.05s (latency 0.000864047s)

 

意思是 k8s 儲存池未設定應用，設定一個即可

[root@ceph01 ~]# ceph osd pool application enable k8s rbd
enabled application 'rbd' on pool 'k8s'

再次檢視應該就不會報錯了

[root@ceph01 ~]# ceph -s
  cluster:
    id:     b356ff71-d7e6-4bdf-abae-9bbd141567c3
