Disks fail to spin down 3 weeks after upgrade
Perhaps coincidental..
Upgraded a ReadyNas duo v1 to 2 x 1TB Seagate drives (from "approved" list). All seemed fine after couple restarts (file operations, and media streaming fine) for 3 weeks or so.
Couple days ago noticed that disks were still spinning from previous evening (spin down had been normal up til then). Noticed also that the FrontView Gui was extremely slow; Duo seemed to be very busy with something. Restarted with front power button (couldn't get to the Duo GUI restart page). Unit did restart, gave a message about improper shutdown, and did two re-sync's (about 9 hours), and reported all is well. Disks still don't spin down. SMART reports seem more or less normal.
Could this be related to the new disks, or some other, coincidental NAS issue? What should I look for in the logs (download all from the DUO)?
Thanks

- Further info from system.log. Some process called noflushd seems to be involved:

So what is "noflushd" complaining about (or is it)?
Rollie Langseth - noflushd is the program that's responsible for idle-disk spindown.
Are you sure that your disks were spinning down before? If so, you might want to try this: Turn spindown off in Frontview, reboot, then turn spindown back on and reboot again.
Also... What disks were in your NAS before you recently replaced them? And have you recently installed any new addons (or updated old addons, especially your media-streaming addon)? - Well, that seems to have fixed it, for now at least!
It is curious that when this problem occurred, the ReadyNAS had become very sluggish to user inputs via Frontview; 10's of seconds for any response, if any. That issue was cleared up by a reboot (via front panel button), but the lack of spin down persisted. There had been a regular (and short) backup to an external USB drive the night before, but that seemed normal.
FWIW, the old drives were Seagate ST3750528AS, while the new ones are Seagate, ST31000340NS (chosen from the Netgear compatibility list, based on alleged 5 yr warranty + vibration "protection"; probably a naïve faith on my part). No other changes made to the NAS.
Thanks for your suggestion!
Of course the warranty is Seagate's not Netgear's.
