[CentOS] pvmove speed

>Running iostat like this will give you utilisation statistics since boot, which will not be inidicative of what's happening now. If you give it a reporting interval, say 10 seconds (iostat -m -x >10), I am guessing you will see very different data (likely high r/s, w/s, await, and derived values).

Thanks for all the pointers guys!
