ALM-12051 Disk Inode Usage Exceeds the Threshold

Updated at:Sep 08, 2020 GMT+08:00

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.

Procedure

Massive small files are stored in the disk.

  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 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.
  3. Use PuTTY to log in to the host for which the alarm is generated as user root.
  4. Run the df -i partition name command to check the current disk Inode usage.
  5. 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 6.
    • If no, adjust the capacity. Go to 7.

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

    • If yes, no further action is required.
    • If no, go to 7.
