1.  Check if the metadata is genuinely too large for the metadata area.
(eg vgcfgbackup into a file)

2.  If so, see if there's anything you can change to make it smaller
eg by changing LVs that are not involved in the pvmove.

We haven't written tools to resize the metadata area yet: you have
to ask for more space when you ran the original pvcreates.

If you really can't shrink it, there are workarounds involving
storing the metadata elsewhere: either on a new PV created with a 
larger metadata area that you add to the VG, or else in the filesystem.

Alternatively, depending what changes you've been making, you might be 
able to restore to a metadata backup - may lose changes if you've been 
updating the data in the areas moved though during the pvmove.
