2. Log in to the iClient S100. On the iClient S100 home page, choose Complex Applications > Video Alarm > O&M Alarms. On the page that is displayed, the Data disk file system error alarm exists, as shown in Figure 6-108.

Figure 6-108 Data disk file system error alarm

3. Log in to the operating system ( How Do I Log In to the Operating System Through a Network Port?) as the root user and run the following command to view logs:

cat /micro_cloud_install/log/ivstool/dev_event_report

If the command output contains "slot x kick reason:Disk fs error," a disk is removed due to a file system fault. The value x indicates the slot number of the failed disk.

Figure 6-109 Viewing the error log

Possible Causes

• Bad block existence on the metadata area of the disk
• Data corruption caused by manual execution of the dd command
• Unexpected power-off

Solution

1. Troubleshoot the system for hardware issues or link faults.
   1. Check whether multiple disks failed.

      If not, go to 1.b. If so, you are advised to stop the manual formatting process and contact technical support.

   2. Run the following command to check the health status of the reseated disk and check whether any errors exist in the results, such as error logs, self-check failure, or bad sectors.

      smartctl -a /dev/sdx

      If not, go to the next step. If so, you are advised to stop the manual formatting process and contact technical support.

2. Log in to the OMU portal, choose Storage > Disks, and check whether the RAID group status meets any of the following conditions:
   • The RAID group is normal.
   • The RAID group is degraded, with only the failed disk affected and no other failed disks detected.
   • Data is being restored, and the failed disk has been replaced and becomes a hot spare disk.

   If so, data can be restored after the failed disk is formatted. In this case, go to the next step. If not, data may be lost after the failed disk is formatted. In this case, contact technical support.

3. Perform the following operations to manually format the failed disk.
4. Create an empty manual formatting flag file.
   1. Log in to the operating system as the root user. ( How Do I Log In to the Operating System Through a Network Port?)
   2. Log in to the backend and create an empty manual formatting flag file.

      touch /opt/SmartData/config/x (The value x indicates the slot number of the failed disk.)

5. Select the software or hardware mode to remove and insert the disk, or restart the system. (You are advised to select the software mode. The following describes how to remove and insert a disk in software mode.)
   1. Obtain the device name corresponding to the slot of the failed disk.

      harddiskidcfg

      Figure 6-110 Device name
      
   2. Obtain the device ID corresponding to the failed disk.

      ls -l /sys/block,

      In the command output, the third field from the right is the device ID, which is presented as x:x:0:0 (for example, 0:2:0:0 in the following figure).

      Figure 6-111 Device ID
      
   3. Run the following command to remove the failed disk:

      echo -n "scsi remove-single-device 0:2:0:0" > /proc/scsi/scsi

   4. Run the following command to insert the disk:

      echo -n "scsi add-single-device 0:2:0:0" > /proc/scsi/scsi

      Figure 6-112 Inserting the disk
      
   5. Check whether the fault is rectified. If so, go to 6. If not, contact technical support.
      1. If the physical status is GOOD, the fault is rectified and the disk becomes normal, as shown in Figure 6-113.

         /opt/SmartData/bin/smio_info disk -f 0 -d x (The value x indicates the slot number of the failed disk.)

         Figure 6-113 Checking the disk status
         
      2. On the OMU portal, check whether the Physical Status of the disk is Normal, as shown in Figure 6-114. If so, the fault is rectified.
         Figure 6-114 Checking the disk status on the OMU portal
         

6. After the fault is rectified, delete the manually created flag to prevent the disk from being automatically formatted when the file system is faulty again.

   rm /opt/SmartData/config/x (The value x indicates the slot number of the failed disk.)
