Not all MP3's found in Library

Server Version#: Version 4.62.1

Problem: When scanning my full library of music from the Top level “Music” folder not all music is being found. There are approximately 51400 files 99% are mp3 files. Example… When scanning full media library Punk files are not there… However if I Create a library of Punk music only the files are scanned so this is not a naming convention thing… I hvae removed the Library and added a new one… The second time same thing but different Files were not found… I’m not sure if

Folder Structure.
Music > Classic Rock > artists
Music > Punk > Artists
Music > Metal > Artists
ect…

I believe I figured it out… Not enough space on disk basically… Filesystem was most likely full.
