Checking the Server Disk Space

Checking the Server Disk Space

This section describes how to check and clear disk space in a timely manner to ensure that the storage space of the eSight server is sufficient.

Impact on the System

When the disk usage exceeds 80%, eSight performance decreases or the server cannot be started.

Reference Standard

The disk usage is lower than 80%.

Procedure

  • Perform the following steps on Windows:
  1. Log in to the Windows operating system as the Administrator user.
    NOTE:

    If security hardening has been completed for the Windows operating system, log in to the server as the SWMaster user.

  2. In the Computer Management window, choose Storage > Disk Management and check the server disk space. You are advised to mainly check the usage of disks where the operating system and eSight are located.
  • Perform the following steps on Linux:

Perform the following operations to check the disk size:

  1. Log in to the Linux operating system as the root user.
    NOTE:
    • If the Linux operating system is hardened, you need to remotely log in to the server as the ossuser and switch to the root user.
    • In the two-node cluster scenario, this operation must be performed on both the active and standby servers.
  2. Run the following command to query the disk usage of the server:

    #df -h

    The following information is displayed: (Values in the Use% column specify disk usage.)

    Filesystem            Size  Used Avail Use% Mounted on 
    /dev/sda2              50G  6.0G   42G  13% / 
    devtmpfs              3.9G  132K  3.9G   1% /dev 
    tmpfs                 3.9G  112K  3.9G   1% /dev/shm 
    /dev/sda3              79G  616M   75G   1% /home 
    /dev/sda4             113G   19G   89G  18% /opt     

Troubleshooting

If the disk usage exceeds 80%, follow instructions in 4.3 to clean up the disk.
