Description

This article explains the procedure to expand disk space in a Policy Enforcer (PE) that is deployed on a Virtual Machine (VM).

Symptoms

Sometimes due to high incoming data and inflow to the PE node, the default disk space may get completely filled.

You can perform the steps in KB34205 - [Junos] Policy Enforcer (PE) Disk Cleanup [juniper.net] to clean up the disk in the PE but if it does not help, you may need to expand the disk partition.

Solution

To expand the VM disk partition in a Policy Enforcer, perform the following steps:

  1. On the VMWare/vSphere Client:

    1. Take a VM Snapshot of the PE node deployment

    2. Power off the VM module/node

    3. Edit the settings of the VM node and click ADD NEW DEVICE. Select Hard Disk and specify the required value for expansion of the Hard Disk in MB/GB/TB

    4. Power on the VM node and log in to the PE Debug Shell

  1. In the PE Debug Shell:

    1. For PE version lower to 22.x Download the PE Disk Expansion zip file(22.x & Below) and transfer the file to your PE server CLI 

    2. For PE version 23.x Download the PE Disk Expansion zip file(23.x) and transfer the file to your PE server CLI

    3. Unzip the file to get the script file: #  unzip resizeFS_PE.zip

    4. Search for the disk partition that you added on the VM client by using the command #  fdisk -l

    5. Execute the script by running the command # sh resizeFS_PE.sh

      • You will be prompted for the disk partition that needs to be used to expand the Logical Volume.

        • Disk /dev/sdc: 107.4 GB, 107374182400 bytes
          255 heads, 63 sectors/track, 13054 cylinders
          Units = cylinders of 16065 * 512 = 8225280 bytes
          Sector size (logical/physical): 512 bytes / 512 bytes
          I/O size (minimum/optimal): 512 bytes / 512 bytes
          Disk identifier: 0x00000000

      • Enter the partition name from the above output, in this case /dev/sdc . (Note that this can be any value in your server such as /dev/sdb or /dev/sda3 .)

This will help you to expand the disk partition for your Policy Enforcer.
