So I ended up using the mount command in a script to mount the external NAS drives. Then removed Plex and removed mount commands.
With some time now to try to get Plex DNLA going again now, I decided to pick up from where I left off.
I wanted to test using the mount command before finally getting the automount to work. But, now I can't mount any of the drives. The NAS hasn't been updated. The NAS is running Freebsd 188.8.131.52 - Sandstorm (revision 775). I have SMB 2.0 enabled on the NAS.
From the command line I've been trying to mount CIFS. I get
mount error(22): Invalid argument
The command I've been trying (multiple variants, ver=2.1, sec=ntlm, etc etc)
I can't tell from the man page what I'm doing wrong.
I've spent a few hours reading many posts and stackexchange but nothing is working.
Is there something that I'm missing?
