I experience disk temperature read errors in My Cloud EX2 Ultra.
I have 2x2TB WD RED disks in Spanning RAID mode. All of a sudden the device shows System Under Temperature notification but of course the room temperature doesn’t suddenly fall down to 0°C. It says "The system temperature is below the specific minimum temperature. Move the system to a warmer location" The diagnostics read Disk1 temp:0°C, and Disk2 temp:42°C. The fan works at a normal speed like 3500-4000 RPM. When i check the logs i find "HWlib unable read HD1 temperature" record. When i do a system test at first it gives me only system temperature fault but after a few minutes drive1 fault is added to it.
After rebooting or hibernating-turning on or system restore everything turns to normal with no disk or temp error but these solve the problem only for until next time. Each time this happens after 10 minutes or so i lose all my connection to the dashboard and the system becomes unreachable.
I strongly feel this is something about the temperature sensors. I do not want to lose my archieve in the disks so i couldn’t try changing the raid mode or format the disks. Has anybody ever experienced anything like this and found a solution? I would reaaly appreciate your comments.
