RN204 Eminent fan failure?
Hi all,
I'm getting this notice in /var/log/messages on my ReadyNAS RN204:
"Setting EDA fan 15 failed - deferring"
I tried switching fan modes and saw this after switching to Quiet mode:
"Setting EDA fan 8 failed - deferring"
Switching to the other modes the "15" code comes back
Does anyone know what this means? Is the fan about to fail or something?
That sounds like an error in the OS. While a NAS that can use an EDA2000 or EDA4000 can set the fan speed in them, there is no similar capability on an EDA500. I retired my EDA500 and other eSATA expansions some time ago, and that error must have come into play sometime after I did so.

So I think I realized what this message is. It started popping up after I connected the Mediasonic Probox 4-bay disk enclosure. What I noticed in "Volumes" is that the Netgear seems to think this is a Netgear EDA500 enclosure (when it's not). My guess is that this alert is coming up because the ReadyNAS daemon is attempting to set the fan speed of the Mediasonic but can't since the Mediasonic's control mechanism is different, thus the error message.
I wonder if there's a conf for the ReadyNAS daemon that can be changed to disable the external device fan control
A ReadyNAS has no capability of setting the fan speed in an EDA500, so that's not the issue. It's also not unusual for the NAS to think your non-Netgear eSATA chassis is an EDA500. Be aware that it might have the drive order backwards (good to know if it reports a disk issue).
I'm not sure how the NAS would know the fan setting didn't "take" if it's the fan itself, unless it completely stopped. So, I fear it's associated with the fan speed controller.
That's odd because I noticed that message popping up only after connecting the Mediasonic box. I guess the real test would be to disconnect it and see what happens and if the message persists or goes away.
I'm still able to change the fan speed on the RN204 itself btw. Of course, I haven't really checked the unit itself to see if the fan is actually blowing faster vs slower. I guess I'll take a look at all this now, including disconnecting the Mediasonic array.
