I made most of the work involved in copying the sparse files on the live
system.

I was following the instruction on your manual on how to backup and
restore. I have done a few successful MDT moves before but nothing that
was done on the live system as it was done in this case.
I have decided to start over on the MDT move and make the move on a
filesystem that is not live. I will perform another lfsck on the new MDT
once the movew is completed.
Thanks.
