Root partition extension in Linux-based Manager

Prev Next

Perform the following steps to extend the root partition in the Linux-based Manager:

Prerequisite:

Take an ALL TABLES database backup of the Linux-based Manager and store it in a remote machine.

Steps:

  1. Log in to the Manager shell.

  2. Shutdown the Manager virtual machine by executing shutdown command.

  3. Log in to the ESXi server where the Linux-based Manager virtual machine is hosted.

  4. Select the Linux-based Manager virtual machine and edit the machine setting to extend the disk space.

    Note

    Make a note of the memory size extended in gigabytes.

  5. Power on the Linux-based Manager virtual machine.

  6. Log in to the Manager shell.

  7. Execute fdisk -l .

    Note

    Make a note of the output displayed on executing the above command.

  8. Execute fdisk /dev/sda.

    The fdisk utility opens.

  9. Type p and press Enter.

    Make a note of the end block of sda.

    For example: In the below output, the end block is 419239935 .

    Device Boot     Start      End          Blocks     Id  System
    /dev/sda1        2048      780287       389120      83  Linux
    /dev/sda2        782336    419239935    209228800   83  Linux
    
  10. Create a new partition by executing n.

  11. The console provides options for partition type. Type P to select Primary and press Enter.

  12. Select the partition number and press Enter.

    Note

    Trellix recommends you to select the default partition number displayed.

  13. Select the first sector for the extended partition and press Enter.

    Note

    Trellix recommends you to select the first block after the end of the available sda blocks as the first sector for the extended partition. That is, if the end location of the available sda is 419239935, then you must specify the first sector as 419239936 (i.e. 419239935+1).

  14. Select the last sector of the extended partition and press Enter.

    Note

    Trellix recommends you to select the default location displayed.

  15. Save the changes to the fdisk utility by executing w.

  16. Reboot the Linux-based Manager by executing reboot command.

  17. Log in to the Manager shell.

  18. Execute fdisk -l.

    Note

    Make a note of the output displayed on executing the above command.

  19. Compare the output of fdisk command in step 7 and step 18. Make a note of the new sda created.

  20. Execute the below command block to extend the root partition:

    vgextend fs /dev/<new_sda>

    Parameter

    Description

    new_sda

    Specify the name of the newly created sda.

  21. Execute the below command block:

    lvextend -L+<memory_extended>G /dev/mapper/fs-root

    Parameter

    Description

    memory_extended

    Mention the memory size extended in gigabytes as specified in step 4. For example, if you have increased the disk space of the Linux-based Manager virtual machine by 50 GB, the memory_extented value should be entered as 50.

  22. Execute df -h and make a note of /dev/mapper/fs-root filesystem size.

  23. Execute the below command block to resize the /dev/mapper/fs-root filesystem size.

    resize2fs /dev/mapper/fs-root
  24. Execute df -h and verify that the /dev/mapper/fs-root filesystem size is extended.
