Hi, do we have any way to monitor which LBAs of which block device are read/written at a given time?
I stumbled upon this, http://southbrain.com/south/2008/02/fun-with-dtrace-and-zfs-mirror.html which is pretty intriguing. Unfortunately on FreeBSD we do not have the DTrace io provider, so his dtrace script would not work. Do we have another option to monitor block device access in a similar fashion?
