ALM-505001003 Disk Usage Is High

ALM-505001003 Disk Usage Is High

Description

This alarm is generated if the maintenance tool detects that the usage of a disk or partition is greater than or equal to the alarm generation threshold (80%) in a detection period (1 minute). This alarm is automatically cleared if the disk or partition usage is less than or equal to the alarm clearance threshold (75%).

Parameters

Name

Meaning

Server name

Name of the server for which the alarm is generated.

Server IP address

Internet Protocol (IP) address of the server for which the alarm is generated.

fileSystem

Name of the server disk for which the alarm is generated.

Threshold

Threshold for generating an alarm.

Clearance threshold

Threshold for clearing an alarm.

Usage

Disk space usage.

Impact on the System

The write operation of the eSight service may fail, and a database exception occurs.

Possible Causes

  • The alarm generation threshold for the disk usage of the eSight server is set improperly.
  • The disk contains too many unnecessary files.
    • The recycle bin is not cleared.
    • The eSight server has received a large amount of data, including NE alarms, events, and logs. The data is exported from the database to disk files in a short time.
    • There are too many temporary data files and backup files.

Procedure

  1. Check whether the alarm generation threshold for the disk usage of the eSight server is set improperly.

    1. Contact the administrator to check whether the alarm generation threshold for the disk usage of the server is set improperly.
      • If yes, contact the administrator for troubleshooting. After the administrator processes it, go to Step 1.2. If you cannot wait for the administrator to process it, go to Step 5.
      • If no, go to Step 2.
    2. Wait five minutes. In the current alarm list, check whether the alarm is cleared.
      • If yes, no further action is required.
      • If no, go to Step 2.

  2. Log in to the eSight server on Xwindows, and check whether the recycle bin is empty.

    • If yes, go to Step 4.
    • If no, empty the recycle bin. Then, go to Step 3.

  3. Check whether there are too many unnecessary files in the disk.

    1. Run the following command to view the file system usage.

      # df -h

      Filesystem            Size  Used Avail Use% Mounted on 
      /dev/sda2              13G  3.3G  8.8G  28% / 
      devtmpfs               12G  200K 12G 1% /dev 
      tmpfs                  24G  7.1G 17G  30% /dev/shm 
      /dev/sda5             1.1G 74M  955M 8% /boot 
      /dev/sda6             8.1G  133M  7.9G 2% /home 
      /dev/sda10            214G 50G  164G  24% /opt 
      /dev/sda7             5.1G  179M  4.9G 4% /tmp 
      /dev/sda8              11G  2.7G  7.4G  27% /usr 
      /dev/sda9             5.1G  824M  4.2G  17% /var 
      shm                    24G  7.1G 17G  30% /dev/shm     

      The Use% column indicates the usage of all file systems. View this column and check for the file systems that their usages exceed the preset threshold.

    2. Access the over-used file system, check the size of all files and directories in it, and sort them.

      # cd filepatch

      # du -sk * | sort -n

    3. Find the directory that occupies too much disk space based on the check result.
    4. Access the directory that occupies too much disk space, check the size of all files and directories in it, and sort them.

      # cd filepatch

      # du -sk * | sort -n

    5. Find the directory or file that causes the high file system usage based on the check result.
    6. Repeat Step 3.4 and Step 3.5 to search for the files that cause the high file system usage and check whether these files can be deleted. You are advised to preferentially delete the installation packages, patch packages, installation packages of the adaptation layer that are backed up before, backup files during installation, and core files. Table 9-259 lists the files of the eSight and database that can be deleted. After you delete the files, go to Step 4.
    NOTE:

    If you are not sure whether the file can be deleted, contact the system administrator or Huawei technical support personnel.

    Unnecessary File

    Cleanup

    eSight installation directory/AppBase/var/iemp/log

    eSight log files

    Back up the files to another computer, and run the rm command to delete all core files.

    eSight installation directory/mttools/var/iemp/log

    Maintenance tool log files

    Back up the files to another computer, and run the rm command to delete all core files.

  4. Wait five minutes. In the current alarm list, check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to Step 5.

  5. Collect the information about alarm handling, and contact the technical support personnel.

Clearing

When the fault is eliminated, the system will auto-clear the alarm. Manual clearing is not required.

The following situations cause failures in automatically clearing alarms. Instead, they need to be cleared manually.

  • The name and IP address of the host for which this alarm is generated are changed.
  • The mounting point for the disk for which this alarm is generated is changed.
  • The server that generates the alarm is not monitored.
  • Active/standby switchover occurs in a high-availability system.
