     1. Back up your data!
     2. Add /dev/sdc1 to the same VG as /dev/sda5 (vgextend)
     3. pvmove -v /dev/sda5 /dev/sdc1
     4. Wait a really long time
     5. Verify nothing is on sda5 (pvdisplay /dev/sda5)
     6. Deallocate sda5 (pvchange -x n /dev/sda5)
     7. Remove sda5 from the VG (pvremove)
