And an easy way to adapt may be thus:
Just backup the last 100M of the filesystem. Then you can consider
the filesystem to be shrunk by 100M. Not really, but it covers
the space that will be lost in the LVM conversion (two extents).
When the conversion is done, you grow the LV back to original size,
(now that's using two extents on another PV you have to provide)
and restore the 100M you backed up to the LV.
The conversion is an offline operation anyways so it doesn't matter
whether you really shrank the filesystem or not, as long as you can
provide enough space for an LV of the original partition size.
