Thanks for the reply. That’s effectively what I did as well, since the 4tb ntfs partition already existed on the drive when I mounted it in M2P. I didn’t create the partition with M2P.
Seems to be working fine, although I’m having an issue where one of the pi3 cores goes to 100% and streaming stops if I attempt to browse my library by Song, Artist or Album instead of Music Folders (using Android app Squeezer). The other 3 cores appear to be sitting idle, so it seems that either M2P or LMS isn’t taking advantage of the pi3’s quad-core processor. Suggestions to resolve this issue would be welcomed, since having streaming stop for any reason is not tolerable.
