I don't know if this is a bug but I wasn't sure where else to post it.
I have two spindown problems in RC2:
I've set default spindown to 15 minutes to help with testing.
(1) The USB disk in Unassigned devices
Unraid tries to spin it down (good!) but doesn't actually do it. That may be a problem with the drive's USB interface so I've cron'd a user script to spin it down with hdparm -y /dev/sdb (which works.) It looks like unRAID never detects that it's spun down (or a successful return from its own spindown call) because absent drive activity I see this every 15 minutes in the log whatever the drive's status:
Dec 20 06:45:05 NAS emhttpd: spinning down /dev/sdb Dec 20 07:00:06 NAS emhttpd: spinning down /dev/sdb
(2) The Fast pool
These are 2.5" 7200rpm WD Blacks which also don't spin down. I see nothing in the log indicating unRAID attempts to spin them down except when I trigger it manually with the Web GUI
Dec 19 21:09:57 NAS emhttpd: spinning down /dev/sdj Dec 19 21:09:57 NAS emhttpd: spinning down /dev/sdf Dec 19 21:09:57 NAS emhttpd: spinning down /dev/sdi
I've attached diagnostics but this is more a request for information. Should I see spindown calls for Pool drives in syslog?
(I should mention I haven't seen the array disks spin down either but they're set to 2 hours and haven't really had a chance. I'll lower it and keep an eye out.)
