When ever I transfer files off of Disk 1, lets say to a external HD using MC, it pegs my CPU out and renders Unraid unusable until all the files have been transferred.
I do notice that on Disk 1 is: System, ISOS, Domains. I do not run any VM's. But, does the System folder have anything to do with this?
Disk 1 is also the only disk that will not Spin Down like the others.
