Getting dd status during transfer

Issue an -USR1 to the process or use killall if you only have 1.

killadd -USR1 dd
kill -USR1 `pidof dd`
[ ... ]

Output will be something like (Here moving a vm machine from a slow 100mbit conn to a faster 1gbit):

root@vm01:~# dd if=/dev/storage/varnish1 of=/dev/virtualdisk/varnish1 bs=4M
