- ..............
- CTSS is in Active state. Proceeding with check of clock time offsets on all nodes...
- Reference Time Offset Limit: 1000.0 msecs
- Check: Reference Time Offset
- Node Name Time Offset Status
- ------------ ------------------------ ------------------------
- node2 -89900.0 failed
- Result: PRVF-9661 : Time offset is NOT within the specified limits on the following nodes:
- "[node2]"
- PRVF-9652 : Cluster Time Synchronization Services check failed
- Verification of Clock Synchronization across the cluster nodes was unsuccessful on all the specified nodes.
- [grid@node2 ~]$
注：节点2的服务器时间出现问题
至此，对Grid的巡检基本上就算完成了
