问题描述

VCN3000版本号:V100R002C00SPC103 

现象:三台VCN下的某一台VCN3000下挂的摄像机录像有断点,如图:

处理过程

1、  根据MU日志分析,发现录像下盘很慢,部分下盘时间达到半分钟以上,这会影响到正常录像,对应MU日志如下;

Line 848: 2016-07-27 13:57:51.465+08:00|   Info|TID:0x7FDE49FD4700|success to SaveAllDataToDisk,|lens = 06723200000000000101n, data time=130, index time=0, db time=0

 能看到数据的存取时间是半分钟以上!

2、  查询SmartData日志,发现记录0号槽位的磁盘为忙盘的记录,故建议现场先讲0号槽位磁盘拔出,由热备盘自动替换,观察效果

能看到有忙盘的记录!

结合以上来看,是由于0曹的硬盘故障导致读取速度慢,甚至忙盘从而使得该VCN3000下的摄像机录像断断续续。

3、0号槽位磁盘拔出,过一段时间后热备盘替换,录像正常,故障解除。

根因
0号槽位磁盘有硬件故障
解决方案
拔出0号槽位磁盘,热备盘替换后及时申请备件更换,故障解决。
