You must mean RENUMBERING inodes. If you move around
the meta-data blocks containing i-nodes, you don't
need to renumber referenced i-nodes, just be able to
find those i-nodes in their new locations.

Sure, presuming you created them to their full
extent at time T0. In practice you keep adding
files to directories, and directory files will
become very discontiguous as time progresses.

It depends, mounted or unmounted filesystem ?
(I would love to be able to do it to a mounted
system, although perhaps slowly, but still be
able to do it with integrity on running system.
If VMS can do it, why can't Linux do it ?)
