Okay I am a complete idiot - I myself called smartctl all the time when checking for the power state of the drives.... Even though I did it with -n standby. blktrace is now more informative. Empty for ~half a minute, then tons of this (notice, still some smartctl in there):
Any way to check the powerstate now (apart from checking physically on the drive LEDs)?
For the record, I found out by doing this:
This includes enough lines to see what initially spawned smartctl.
