So, i'm testing some settings to put my HDDs into standby mode to keep their temps down while not in use (these disks will only be activate once a day for remote replication tasks).
In any event, i was able to get the disks to spin down but i lost the ability to monitor their temperatures. When i go to Reporting->Disks TrueNAS advises that the temperature of the disks are not available and in order to enable it i should put the disks either in "HDD Standby - Always on" or to check the option "Force HDD Standby".
I did the second and the temperature of the disks are still not available. Do anybody knows how to get the disks to spin down and also report their temperatures? I'm using a pair of WD Red Pro WD161KFGX.
Also, i was a bit hesitant about using the "Force HDD Standby" option as there is very little documentation of it. According to this youtube video Spinning Down Disks | Managing TrueNAS Core , and i quote, this is "normally to force it into standby mode if its running software checks like a scrub or doing a snapshot". The implication here is that those extremely important tasks could be interrupted by the "Force HDD Standby" feature.
Do anybody know if this is true? Because if that is the case i cannot imagine why would anybody want such feature.
