Hi,
I wonder if is possible to configure the gmirror rebuild speed.
Neither I've found any related info in the net nor the man pages.
This doesn't do exactly what you want, but might address your problem,
anyway: try "renice +20 [gmirror PID]", where "[gmirror PID]" is the PID
of the system process handling your mirror (ps auxw | grep g_mirror). I
know that back when ZFS code ran in separate processes back in RELENG_7,
renicing the zpa_zio* and spa_scrub_thread processes made the system a
lot more responsive during a scrub.
