Yes, the mysql is on the Ubuntu BE, and the FE is trying to access it. The
weird part is, it works on and off - i think it works every time I try to
do a "chmod 775" on the backend but i think with a rescan it gets messed
up.

Here's what the backend logs:

https://pastebin.com/yrAsWNeZ

I see "can't write to" issue and some "AutoExpire: CalcParams(): Max
required Free Space: 1.0 GB w/freq: 15 min" thing which when I search seems
to be some TV Tuner issue

I somehow have this feeling its a file permission thing. Every time I do a
"chown" or "chmod" - it converts my nfs shared folders to the following:
