Summary: How do I pvmove data with LVM2 if contiguous runs of
PEs in the source LVs will have to be split up to make them fit?
Quick answer:
LVM2 doesn't support this directly yet: it's being worked on.
Until it's done you need to edit the metadata [using vgcfg*]
to split the segments into smaller ones before running pvmove.
[Might also need to recompile disabling section merging code
which would undo your splitting.]
