Increasing Size of BitrixVA LVM-Partition

Scenario: the size of system disk was increased from 20GB to 100GB, as was done previously in VMWare Player.

Then, the actions to change LVM-partition size will be the following:

1. Check, what devices/partitions are available at the moment via the command:

   fdisk -l

   

2. Verify, that the space did not increase automatically via the command:

   df -h

   

   Volume group name and the name volume are also visible (we will have different ones):

   • cl - volume group name;
   • root - volume name.
   
   
3. Create a new sda3 partition - partition type: Linux LVM (code type 8e) on the unpartitioned space. To do that, start working with the sda device via the command:

   fdisk /dev/sda

4. Next, create a new partition via the n command:
   • primary (primary partition) - p and Partition number (1-3, default 3): 3 command (because we had 2 logical partitions sda1 and sda2 - p.1);
   • in this case, first and last sectors are selected by default - this way, partition will be created by using all available free space on disk;
   • indicate partition type - t and Partition number (1-3, default 3): 3 command;
   • enter partition code type, corresponding Linux LVM - 8e;
   • see the partition table - enter p command and make sure, that all is correct;
   • Partition sda3 is created. To save the updated partition table and to exit from fdisk - w command.

     

5. For the system to load the new partition table, reload the Virtual Appliance:

   reboot

6. After the reset, it is necessary to create a sda3 physical volume:

   pvcreate /dev/sda3

7. Next, expand the volume group to a new space, using the cl volume group name (which we have memorized previously in p.2):

   vgextend /dev/cl /dev/sda3

8. Now, expand the logical volume, by using the root volume name (hich we have memorized previously in p.2):

   lvextend -l+100%FREE /dev/cl/root

9. Scan disks for the for the availability of volume groups and activate all volume groups that are found:

   vgscan
   vgchange -ay
   

   

10. Find the type of file system:

    file -s /dev/sda1

    

    See, that file system is XFS.

11. And finally, expand XFS file system (may require time):

    xfs_growfs /dev/cl/root

    

    Note: If the file system is not XFS, but, for example, id ext4 or reiserfs, then the commands will be the following (with account of cl - to group name and root - volume name from p.2):

    • resize2fs /dev/cl/root - for ext4;
    • resize_reiserfs /dev/cl/root - for reiserfs;

12. Check the final result:

    df -h
