Constant disk writes + alerts

[platinumjsi]

Ok two things here, first I seem to be having constant disk writes to my drives, yet I am not copying anything to the NAS and havent done all day?

Second a couple of my drives seem to hit 40 degrees (critical threshold limit) a lot during the day, but I am not receiving any emails about it, havent done for a few days now, received a couple of emails when it did its first long smart check but that was it, test emails work fine?

Cant screenshot the temp logs as I had show console messages in footer and was looking at it from there, its now deleted them because the file is over 100k?
There was about 30 logs though saying the drives hit 40 degrees, not worried about the temp as the drives are rated for up to 65 degrees and never seem to go over 43 but I find it odd that there was about 30 notices there and no email?

The disk activity is completely normal, assuming your .system dataset is on your pool.

I can't explain why you aren't getting the temperature warning emails. Do you receive regular security run output emails?

We currently discuss the temp warning emails problem in another thread: https://forums.freenas.org/index.php?threads/smart-temperature-notification-emails.38586/

You should definitely correct your drive temp problem, they'll not live long if they are often at more than 40 °C.

security run output emails?

Drives are rated to 65 degrees so 40 should be fine, nothing I can do to improve the temps, using a Silverstone DS380 case only 3 of the drives ever hit 40 degrees, I assume its the bottom one and the two top ones.

We know from real world data than past 40 °C the failure rates sky rocket whatever the drive operating range temp is, see the google paper on this subject.

It's not a settings problem, it's a bug, please read the other thread.

Right ok will have a read, odd that it was working and now isnt.
Going to look at a few things case wise to try and drop the temps, move 3 drives to the top bays, 3 to the bottom ect.
