Specifies the role for which the alarm is generated.

HostName

Specifies the host for which the alarm is generated.

DirName

Impact on the System

Service data fails to be written into the partition, and the service system runs abnormally.

Possible Causes

  • The hard disk is removed.
  • The hard disk is offline, or a bad sector exists on the hard disk.

Procedure

  1. On the MRS cluster details page, click Alarms.

    For MRS 1.8.10 or earlier, log in to MRS Manager and click Alarms.

  2. Click Alarms, and click the alarm in the real-time alarm list.
  3. In the Alarm Details area, obtain HostName, PartitionName and DirName from Location.
  4. Check whether the disk of PartitionName on HostName is inserted to the correct server slot.

    • If yes, go to 5.
    • If no, go to 6.

  5. Contact hardware engineers to remove the faulty disk.
  6. Use PuTTY to log in to the HostName node where an alarm is reported and check whether there is a line containing DirName in the /etc/fstab file.

    • If yes, go to 7.
    • If no, go to 8.

  7. Run the vi /etc/fstab command to edit the file and delete the line containing DirName.
  8. Contact hardware engineers to insert a new disk. For details, see the hardware product document of the relevant model. If the faulty disk is in a RAID group, configure the RAID group. For details, see the configuration methods of the relevant RAID controller card.
  9. Wait 20 to 30 minutes (The disk size determines the waiting time), and run the mount command to check whether the disk has been mounted to the DirName directory.

    • If yes, manually clear the alarm. No further operation is required.
    • If no, go to 10.

  10. Collect fault information.

    1. On MRS Manager, choose System > Export Log.
    2. Contact the O&M personnel and send the collected log information.
