If pvmove fails, you can use 'pvmove --abort' to abandon it
or 'pvmove' on its own [or with same source pv as before] to
retry. xxchange -ay may also attempt to restart pvmoves in
progress (leaving a pvmove daemon running).

Need more precise description of what you mean by 'hanging'.
And the usual diagnostics: debug log file from the command that should
have set the pvmove running, any kernel error messages, lvm.conf, a copy
of the current VG's metadata [e.g. with vgcfgbackup -f] etc.
If pvmove process itself freezes, then a long/wide 'ps' output for that
process, kcopyd & kmirrord (incl cols: NI, VSZ, RSS, STAT
and symbolic WCHAN).
