RN Ultra 6 - System Temp
Hi all, I have a ReadyNas Ultra 6 with 6 x 4TB WD Red HDD's and all working fine for a couple of years now and running on OS 6.10.5 Hotfix 1. Over the last few weeks I have noticed that the NAS ...
The reported system temperature does rely on a sensor that can go bad. If dust at the sensor was the problem, it would typically be too low. But a poorly working fan can come into play.
The reported (and acted upon) temps also rely in the sensor configuration used by lm_sensors. So, let's make sure that's right. From ssh, execute
ls ./etc/sensors.d/ -all
You should see that is points to the ULTRA6 configuration:
system.conf -> /etc/frontview/sensors/ULTRA6.conf
Then do
cat /etc/frontview/sensors/ULTRA6.conf
And one of the sections should be:
label temp2 "System"
But here is something odd:
chip "coretemp-isa-0000"
label temp2 "CPU"
compute temp2 @%35, @%35
I don't see % being a valid operator in lm_sensors. So, I think that's just assigning 35°C to be the reported CPU temperature, because either the chip doesn't really provide it or it's considered unreliable. That you say the CPU is "solid" at 35 seems to confirm that. So, perhaps restricted air flow or poor conduction between the CPU and it's heat sink are problematic.
I no longer have an Ultra6 and only ever used it as a backup, so I never really paid attention to the temperatures since they were never reported as too high. Maybe somebody else can let you know if the Ultra6 system temperature typically runs high.
Hi Sandshark ,
Many thanks for jumping on board.
The reported (and acted upon) temps also rely in the sensor configuration used by lm_sensors. So, let's make sure that's right. From ssh, execute
ls ./etc/sensors.d/ -all
I logged into the NAS in question and entered the command above and got the "No such file or directory" response.

Try
ls /etc/sensors.d/ -all
(leaving off the initial .)
Tryls /etc/sensors.d/ -all
(leaving off the initial .)
This worked.
Yes it stated exactly as you mentioned.
chip "coretemp-isa-0000"
label temp2 "CPU"
compute temp2 @%35, @%35
ignore temp3
Also further down was
label temp2 "System"
set temp2_min 1
set temp2_max 80
ignore temp3
While this confirms the earlier post - just to note that previous to creating the original post and reason for this was that while watching a video on the NAS using Plex during the movie it would suddenly stop and give a message on Plex saying that there was an issue with the file and could not be found. But if I immediately go to resume the video it would play. It seems like a temproary disconnect of some sort.
Today after your post on checking the fans I went and checked the NAS and removed the drives and there was a lot of dust - fine dust and cleaned all. Booted the NAS back up and it runs still a bit sluggish and System Temp varying between 71 and 73ºC but no disconnect tonight at all.
Earlier StephenB you mentioned to carry out a disk test. I presume you mean using the following options:
Scrub, Defrag, Balance, Disk Test. Which order should these be perfomed and would my data be secure (I know you will say ensure a backup is carried out but should the data be safe even though the disks will have an increased load while tsting,
Many thanks in advance again

I was thinking the disk test first.
Scrub and Balance might also be useful - balance might improve your performance.
Personally I use the maintainance schedule to run one of these tests every month.

Yes, consider that said...
But the tests themselves are safe, the risk is only that disks might fail while they are running.
