Hmmm, 275G filesystem inside a 250G lv??? You should have done the reverse...

That's ok.

Now you have to be brave.
You should remove sda2 and recreate it with a smaller size (for example 310G).
The content should not be lost, as the metadata is at the start of the partition.
(refer another mail of mine from 23/8/2008 "lvm resizing and shifting" on this issue)

If you are still alive, you then:
- enlarge the pv to 310 (try to avoid manual specification, always better autodetect).
- enlarge the lv if you want
- enlarge the filesystem if you want
