Extending disk size of vmware disk

1. Power off the virtual machine.
2. Edit the virtual machine settings and extend the virtual disk size. For more information, see Increasing the size of a virtual disk (1004047).
3. Power on the virtual machine.
4. Identify the device name, which is by default /dev/sda, and confirm the new size by running the command:
   
   # fdisk -l
5. Create a new primary partition:
   1. Run the command:
      
      # fdisk /dev/sda (depending the results of the step 4)
   2. Press p to print the partition table to identify the number of partitions. By default, there are 2: sda1 and sda2.
   3. Press n to create a new primary partition.
   4. Press p for primary.
   5. Press 3 for the partition number, depending on the output of the partition table print.
   6. Press Enter two times.
   7. Press t to change the system's partition ID.
   8. Press 3 to select the newly creation partition.
   9. Type 8e to change the Hex Code of the partition for Linux LVM.
   10. Press w to write the changes to the partition table.
6. Restart the virtual machine.
7. Run this command to verify that the changes were saved to the partition table and that the new partition has an 8e type:
   
   # fdisk -l
8. Run this command to convert the new partition to a physical volume:
   
   Note: The number for the sda can change depending on system setup. Use the sda number that was created in step 5.
   
   # pvcreate /dev/sda3
9. Run this command to extend the physical volume:
   
   # vgextend VolGroup00 /dev/sda3
   
   Note: To determine which volume group to extend, use the command vgdisplay.
10. Run this command to verify how many physical extents are available to the Volume Group:
    
    # vgdisplay VolGroup00 | grep "Free"
11. Run the following command to extend the Logical Volume:
    
    # lvextend -L+#G /dev/VolGroup00/LogVol00
    
    Where # is the number of Free space in GB available as per the previous command. Use the full number output from Step 10 including any decimals.
    
    Note: To determine which logical volume to extend, use the command lvdisplay.
12. Run the following command to expand the ext3 filesystem online, inside of the Logical Volume:
    
    # ext2online /dev/VolGroup00/LogVol00
    
    Notes:
    • Use resize2fs instead of ext2online if it is not a Red Hat virtual machine.
    • By default, Red Hat and CentOS 7 use the XFS file system you can grow the file system by running the xfs_growfs command.
13. Run the following command to verify that the / filesystem has the new space available:
    
    # df -h /

The OP stated that he was using the XFS filesystem. The tool resize2fs works with ext2, ext3 and ext4 only.

There's a similar tool available for the XFS filesytem called xfs_growfs. You'll most likely have to install it first

sudo yum install xfsprogs.x86_64 --assumeyes

then mount your filesystem

sudo mount -t xfs /dev/sdf /vol

now you can extend the filesystem

sudo xfs_growfs /vol

df -h should now show more available space

I hope this helped :)

Tip: ext4 filesystem is the recommended filesystem for EBS volumes ( for the future )
