[lvm-devel] [PATCH 2/5] Call _check_pv_sizes() from vg_read_internal(), print warning.

[Dave Wysochanski]

If we read a vg with any PVs that have changed sizes since pvcreate,
flag it as a warning for now.

We probably want to provide a command to safely repair this condition,
perhaps vgck and/or pvck.
