Re: [linux-lvm] pvmove to smaller PVs



I'm no expert, mostly just a lurker on this list, but couldn't you SoftRAID the 4 120GB's together then PV move the 300GB to the logical disk?

There's no logic to do that yet.  It can only move complete sets of
contiguous extents.

As you found: break up contiguous extents explicitly on
the command line by telling it to move smaller parts that it
can handle.

Use '--alloc anywhere' if you need to move data within a single PV.
