ALM-12051 Disk Inode Usage Exceeds the Threshold

Description

The system checks the disk Inode usage every 30 seconds and compares the actual Inode usage with the threshold (the default threshold is 80%). This alarm is generated when the Inode usage exceeds the threshold for several times (5 times by default) consecutively.

To change the threshold, choose System > Threshold Configuration > Device > Host > Disk > Disk Inode Usage > Disk Inode Usage.

When the hit number is 1, this alarm is cleared when the disk Inode usage is less than or equal to the threshold. When the hit number is greater than 1, this alarm is cleared when the disk Inode usage is less than or equal to 90% of the threshold.

Parameters

Parameter

Description

ServiceName

Specifies the service for which the alarm is generated.

RoleName

Specifies the role for which the alarm is generated.

HostName

Specifies the host for which the alarm is generated.

PartitionName

Specifies the disk partition for which the alarm is generated.

Trigger Condition

Generates an alarm when the actual indicator value exceeds the specified threshold.

Impact on the System

Data cannot be properly written to the file system.

Possible Causes

  • Massive small files are stored in the disk.
  • The system is abnormal.

Procedure

Massive small files are stored in the disk.

  1. On MRS Manager, click the alarm in the real-time alarm list. In the Alarm Details area, obtain the IP address of the host and the disk partition for which the alarm is generated.
  2. Use PuTTY to log in to the host for which the alarm is generated as user root.
  3. Run the df -i partition name command to check the current disk Inode usage.
  4. If the Inode usage exceeds the threshold, manually check small files stored in the disk partition and confirm whether these small files can be deleted.

    • If yes, delete files and go to Step 5.
    • If no, adjust the capacity. For details, see the FusionInsight HD Capacity Adjustment Guide. Go to Step 6.

  5. Wait 5 minutes and check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to Step 6.

Check whether the system environment is abnormal.

  1. Contact the operating system maintenance personnel to check whether the operating system is abnormal.

    • If yes, go to Step 7 to rectify the fault.
    • If no, go to Step 9.

  2. Wait 5 minutes and check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to Step 9.

Collect fault information.

  1. On MRS Manager, choose System > Export Log.
  2. Contact technical support engineers for help, detail see technical support.
