Quotebefore you read the whole thing let me get to the point: can somebody tell me how to disable smart readings completely? i know the risks and its only to check my theory for peace of mind. i have commented out the DEVICESCAN line in /etc/smartd.conf but i cant seem to restart the smart reading service - partly because i dont know what the service is called and partly because neither systemctl nor service seem to be implemented in unraid.
so here goes the long version why i want to know that:
I have read many bug reports of this, but nothing ever came of it in any thread. its always the plugins, the vms, a docker container etc. Well, as with so many people not for me, it could not be pinned to any of those culprits.
I have booted in safe mode, i have manually disabled docker and vm service, no mover, no script, my appdata and system shares are on cache only and i have made sure not a single computer on my network is connected to a share and still, the data disks keep spinning up again and again.
the funny thing is i have tried so many hours to find out why and nothing came of it. i checked with open streams plugin - nothing. i checked with disk activity plugin - nothing. i have even made a new config just to be sure... even unraids own gui did not increase read or write counts for 2 consecutive spindown/spinup cycles.
i am completely lost with this and i still dont think anybody can help me, but i refuse to let this one go without at least opening up another bug report as so many have done before me with no help.
here are my diagnostics, although they wont help you im afraid. i know i know, smart only reads when the disk is active and so on... every bug report was full of it. well as i have detailed above, NOTHING accessed the disks when they spun up. so either its a bug or something with smart does not work. i am convinced its smart because it also had trouble displaying the drive temps correctly with my raid controller (in hba mode).
what makes me believe its not an issue with my raid card or other hardware is that parity stays spun down.
please just let me disable smart reading and see if the disks keep spun down.
