The dashboard is only displaying the drive temperatures for the first pool.
All drives within the first pool are fine (they report a temperature in the GUI), but none of the drives in the second or third pool is reporting a temperature in the GUI.
Drives are attached via an HBA and directly onboard.
First array (fast) = HBA
Second array(purple) = onboard
Third array (red) = HBA (same as the first array)
smartctrld can see the temperature:
smartctl -A /dev/da4 |grep Temp 194 Temperature_Celsius 0x0022 120 101 000 Old_age Always - 30
I can remember this worked in the version before.
Currently i am on the version FreeNAS-11.2-U6
