Dividing and Mounting Disk Partitions

Dividing and Mounting Disk Partitions

This section applies to the scenario in which a disk array is mounted before the eLog collector is installed and does not apply to the scenario in which disk arrays are mounted for capacity expansion. For the latter scenario, search for "collector capacity expansion".


If a server connects to a disk array, you must install and configure the disk array in advance.


You are advised to create the /opt/huawei/LogCenterData directory, mount the disk array space to this directory, and install the eLog collector. If the sequence is incorrect, the mounting will fail.


  1. Log in to the server as the root user.
  2. Create the /opt/huawei/LogCenterData directory as the mounting target.

    test:~ #  cd /opt
    test:/opt # mkdir -p /opt/huawei/LogCenterData

  3. Use a GUI access tool to log in to the server as user root, click Computer, and then click YaST.
  4. Click System on the left part and then click Partitioner on the right.

  5. Click Yes.

  6. Choose Hard Disks from the navigation tree. Information about all disks on the system is displayed in the right area.

    As shown in the following figure, the Mount Point field is empty for disks sdb and sdc, indicating that the disks have not been partitioned or mounted. The following part uses the sdb disk partition as an example.

  7. Choose Volume Management from the navigation tree, and click Add and choose Volume Group to add volume group.

  8. Enter a volume group name (vgcollector in this example), select /dev/sdb, and click Add. Then click Finish.

    Here, you can add multiple physical disks as required.

  9. Choose vgcollector from the navigation tree and click Add.

  10. Enter the logical volume name (vcollector in this example) and click Next.

  11. Set the disk size (maximum size in this example) and click Next.

  12. Select Data and ISV Applications and click Next.

  13. Set Formatting Options to Format partition, select XFS from the File system drop-down list, set Mounting Options to Mount partition, enter /opt/huawei/LogCenterData for example in the Mount Point text box, and click Finish.

  14. On the Expert Partitioner page, click Next and then click Finish.


Run the df -TH command to check whether the mounting information is correct.
