ReadyNAS RN104 shutdown because disks exceed safe temperature after defrag - follow up thread
Hello StephenB , hello all, I'm "reopening" my old thread from April 2020 because I have new details which may help to track down the issue. StephenB sorry for tagging you directly but you were invo...
I have similar issues with defrag and temps over 60 degrees. It started after I upgraded from 6.10.6 to 6.10.8. Prior that everything worked with no issues.
My setup is 4x WD RED 10tb.

Are you also seeing the temp problem when you aren't running defrag?
It sounds like the process that reads the temperature and and adjusts the fan speed is getting locked out (no CPU time available) until the defrag process completes. Those processes hogging CPU time and making other things (like the admin interface) not work well has been an issue for a while, and it seems it's gotten worse with the latest updates.
Frankly, I'd quit running defrag. It's usefulness in a RAID system is limited. But that won't help you with a balance (which, hopefully, won't run long enough to matter) or a scrub (which will run long).

No. Even 4 days scrub does not increase temps that much.
