It looks like the PE table does not match what is in the LV table for
that LV (i.e. the PE table has 626 PEs that claim to be part of the LV,
but the LV says it has only 625 LEs allocated).

Two possibilities: you recently added an LE to the LV and you had a crash
(or an LVM bug), or somehow you had an error writing to disk.  You can try
restoring a copy of the metadata with vgcfgrestore to see if it helps.

Failing that, check pvdata -avP <disk> to see what is wrong.
