Thanks Christian, that makes perfect sense. I don't know why it didn't
click for me earlier but I get it now.

Your file system although only 59% used still occupies the PEs. The space is
allocated by the file system and thus also by the logical volume group.
To fix this you need to:
1) Unmount and reduce your file system size first.
2) Then reduce the logical volume using lvreduce
3) Then use pvmove to remove the failing physical device
The tool you use to resize your file system is obviously dependant on the
file system, and I can't see what you are using so you'll have to work that
I think this is all right, but it's off the top of my head so if I'm wrong
please correct me guys.
