Issue/Introduction

Symptoms:

• Converting a Linux virtual machine with LVM volume fails with an error similar to:
  
  

Volume group "Volume2" has insufficient free space (3104 extents): 12800 required.

• Running the command on the source machine:

# vgs -o +vg_free_count,vg_extent_count | grep 'VSize\|Volume2'

You see entries similar to:

Environment

VMware vCenter Converter Standalone 5.0.x
VMware vCenter Converter Standalone 5.1.x
VMware vCenter Converter Standalone 6.x
VMware vCenter Converter Standalone 5.5.x

Cause

This issue occurs when a whole volume group being converted exceeds 2TB. Partitions cannot exceed 2TB for MBR volumes.

Resolution

To resolve this issue:

Option 1: Shrink the logical volume or move some of the data to a new volume group so that the used space does not exceed 2TB.

Option 2:

1. Convert the machine without including the problem volume
2. Manually create a large LVM on the converted machine which spans a 2TB disk plus another disk.
3. Stop any I/O on the source machine, and then SCP the data from the source machine to the destination.
