Publication Date:  2019-07-30 Views:  451 Downloads:  0

Issue Description


Server Type:NVR6128


Version: eSpace IVS V100R001C30LGLE01SPC200


Problem Description: Customer was unable to see the playback ** of specific IP-cameras despite of all services running and **ing status is showing that cameras are **ing indeed.


 


Alarm Information

Cannot see the playback **.

Handling Process

According to the MRU logs below,

2015-06-25 15:57:26.836 | Error         | 0xdd323ba0 | check_disk | Disk.cpp:223 | Check disk fail, disk is bad or open file failed. diskPath=/mrumnt/RecordFile1, flag=7

This error means that the disk cannot be read/written, so we cannot r**d.

Here is the way we handle:

·         Umount the r**ding path /dev/md1

·         Repair the system

·         Mount the r**ding path

Since the operation is risky which has the possibility to lose all the r**ding, please ask for help from Huawei Engineer immediately when problem occurs.

Root Cause

The disk cannot be read/written, so we cannot r**d.


The file system for r**ding path is XFS, since we use 7*24 to r**d, the disk will be read/written all the time, so the disk/file system has that possibility after running a long time.

Solution

If we meet the error in the logs below, 
2015-06-25 15:57:26.836 | Error         | 0xdd323ba0 | check_disk | Disk.cpp:223 | Check disk fail, disk is bad or open file failed. diskPath=/mrumnt/RecordFile1, flag=7

Here is the way for your to refer to,

·         Umount the r**ding path /dev/md1

·         Repair the system

·         Mount the r**ding path

Since the operation is risky which has the possibility to lose all the r**ding, please ask for help from Huawei Engineer immediately when problem occurs.

Suggestions

1. For the user of NVR6128 system, we suggest to check the r**dings from time to time.

2. For the troubleshooting of r**ding problem, we should check the file system of r**ding path.
