[linux-lvm] PFree is 0 on a drive with nothing on it

[Adam Mooz]

That is correct.  All drives are part of 'fileshare/lv_fileshare',  
which only has 400GB of data on it at the moment; which I can see  
reflected in the PFREE columns of the PVS output.  Is there an easy  
way to force the LVM to rescan it's allocation unit or would I have to  
remove the drives and re-insert them into the LVM?
