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.
So I'm pretty sure the Mediasonic box being connected to the RN204 is what is causing the "Setting EDA fan 15 failed" message to pop-up.
I powered everything off and only powered the RN204 back up. Checked kern.log and the message didn't appear at all for the entire time I had the unit up without the Mediasonic connected (this was probably a period of 10-15 minutes or so). These "Setting EDA fan" messages would pop-up every couple of minutes btw.
I powered the Mediasonic back on and rebooted everything and now the message is back up.
So it seems there's some process within readynasd on the RN that is attemping to send a fan control setting message to what it *thinks* is the EDA and it's obviously failing since it's not actually an EDA that's connected.
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.
Yea, maybe they changed something... in either case, the error is still propogating. I wish there was a way to silence it but I don't think there will be a very easy solution to this, especially now that these units are EOL
