Hi,

pvmove is generally transparent to the layers above, so you can continue 
using the system as usual while a pvmove is in progress. While I have 
never seen pvmove actually fail (My desktop encountered a power failure 
mid-operation once, and it just continued as if nothing had happened 
after rebooting), with a failing hard disk, I would avoid any additional 
IO while the operation is in progress.
