afaik, there's no way to do this 'in place'.
you'd need to boot into rescue mode, create the new XFS partition, copy the data across, then make the new partition live.

Hi Folks,
Can you guide me about how to convert the CentOS file system from EXT3/EXT4 to XFS without loosing data? I have tried search in google about this but I couldn't get the relevant idea.
