Root partition extension in Linux-based Manager

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

Note

The growpart RPM is required to extend the root partition in AWS. Thus, the below steps will not be applicable to Linux-based Manager in AWS. To extend the partition, see   Root Partition extention in AWS Public Cloud.  

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.    

   he 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.
