ReadyNAS fan speed spikes
I just recently got an RN428 unit for home use, and popped in some HDDs I had lying around for a test run with a small volume. So far, I only have 3 out of 8 bays filled, with total system temp remai...
Ok, so I finally got my hands on some new drives, namely HGST Dekstar NAS 4TB drives. Plugged them in, and had the unit recreate the volume. So far (about 4 hour in) no random fan spikes anymore, and all drives report a realistic temperature arounf the 45C mark.
The conclusion seems to be that crappy old drives with faulty temp reporting will throw off the temp snesors and cause the fans to spike every once in a while. The problem doesn't appear to be something in the unit itself. Fan speeds also seem to increase with somewhat better incremental steps if the drives do get hotter.
UPDATE: The volume finished building and I did an upgrade to 6.10 (including reboot). Still no apps running or data read/written. Fan spikes continue, although a little longer apart now (every 20-30 minutes, sometimes more often). Switching to quiet fan profile doesn't help.
This is still with only 3 out of 8 bays populated and no data activity on the disks.
