	Hey there, running 4.5-RELEASE-p3 with an SMP kernel, and I cannot believe I did not see this message before.

twed0: <RAID5, Degraded> on twe0
twed0: 229033MB (469060608 sectors)
twe0: command interrupt
Mounting root from ufs:/dev/twed0s1a
twe0: AEN: <unknown AEN 0x221>
twe0: AEN: <unknown AEN 0x321>

	Oh boy, I cannot believe I did not realize this, but the array has been degraded the whole time!  Since I am not running STABLE, I do not have ata-control.  Is there a way I can find out which drive is bad short 
of power cycling and taking a look at it?  Do those error messages tell me which drive is down?  Surprisingly, the performance has been quite excellent for a "degraded" system.  I wonder if it is just a dodgy 
interconnect to the IDE backplane.  (Pretty sure we ran into that issue when we were testing here before deploying it.  Yes, it is as a colocation facility so I cannot just out right look at it easily.  )  Is there a way to nab 
the status of it short of power cycling it?
	Maybe I should cvsup to get ata-control...
