October 5, 2025Oct 5 First off: yes I am guilty, the post I read even had a warning in itBut I still tried `powertop --autotune` to see the results, and at first I didn't notice anything not working.But then I saw that my 3rd array disk (smallest current one and also oldest, makes sense that it maybe can't handle some options) was marked as disabled (disabled, contents emulated).I didn't find any way to activate it, and reading about powertops said that it's changes shouldn't be persistent, I did reboot my system.and... it completely didn't find the disk anymore. I did not find anything about disabling the med_power_with_dipm option again...So I tried a shutdown, waited a few min and started again.I'm back to "device disabled content emulated".I have 2 cache SSDs and my array is 2x 8TB, 1x 6TB + 8TB Parity. Since my current MB only has 4 SATA Ports 2 HDDs are connected via an PCIe (x4) to SATA Card. I am not 100% sure that the 6TB (problematic) one is connected via this, but at least one other drive connected there is working, so I am not sure this is the issue...lsscsi still shows the disk. I'm not sure about the SMART readings that Unraid shows - are they also "emulated" or current?This thread suggests that the disk needs to be rebuild - but I cannot find an option for it, with the array running or not...So I'm at a loss on how to proceed...
