OK, replaced my dead power supply on my ReadyNAS Business/Pro model RNDP6000. I'm now getting this alert once a minute: 3VDUAL power is out of normal range [expected: 3.30 current: 3.04]. AV...
Since the 24-pin ATX connectors is not repeatedly connected and re-connected, the fact that it is "old" is unlikely to be the problem. 3,3V is on 4 wires -- the orabge ones. You could check that they are making good contact, but I suspect you have a power supply that's genuinely supplying out-of-spec voltage. Did your technician check that voltage under the load of the NAS?
If you've checked and the voltage really is OK, you could edit /etc/sensors.d/system.conf via SSH and change the test limits for the 3.3V. The lines that control that are:
label in2 "AVCC"
set in2_min 3.3 * 0.90
set in2_max 3.3 * 1.10
label in3 VCC3
set in3_min 3.3 * 0.90
set in3_max 3.3 * 1.10
I hate to say anything derogatory about somebody I've never met, but anyone who thinks that's not a problem and says it "could be" because of old connectors and then does no further investigation does not deserve the title "technician".
Jusr FYI, the drives put no load on the 3.3V, so powering up without them would be as good a test on the 3.3V as with them. Of course, the NAS won't boot to the condition where you see if the NAS itself reports the low voltage. But you could use a scratch disk for that. It takes very little time for it to initialize a single-drive volums.
