ceph故障处理

1.报错：health_warn：clock skew detected on mon c ，mon b

参考：https://blog.csdn.net/tjsquall/article/details/110367481

问题分析：看问题报错情况感觉应该是发生了服务器时钟偏差的问题

修改：mon clock drift allowed = 0.5

kubectl -n rook-ceph get ConfigMap rook-config-override -o yaml

apiVersion: v1
data:
  config: |
    [global]
    mon clock drift allowed = 0.5
kind: ConfigMap

重启mon监控

[root@kv-master-00 ~]# kubectl -n rook-ceph delete pod $(kubectl -n rook-ceph get pods -o custom-columns=NAME:.metadata.name --no-headers| grep mon)
