Sooo… Finally time for that topic.
Today I tried fstab samba in the Pi. According to following manual:
Well…
MY PI
My girlfriend had problems with Grey’s Anatomy - stuttering etc. With fstab, last episode worked flawless. Have to test furthermore.
HIS PI
I interrupted him watching a series from USB. Worked >flawless<
After the series was over, I set up fstab the same way I did on MY PI.
Set up the interface, so “Series” directly routes to his series drive and “Movies” to the movies drive. (path was /mnt/series/)
Now… Guess what. When selecting “Series”, the list was almost instantly up (before it was like 3-5 secs delay until the list was loaded). Back, now to “Movies” - Same fast list loading.
Chose a Movie - tested an AVI and a MKV Version.
In the first 5 seconds… Stutter. After 10 secs - complete hickup. I finally noticed something! The WLAN Dongle lost connection. It blinked like it was searching for a signal. Pi was warm, not hot. No temperature signal or anything. Sadly, I didn’t have the chance to check debug if CPU Cores were at 90-100%.
The complete hickup endured about a minute, I then disconnected the WLAN Dongle… Finally could step one menu down, exit the movie. As it might be seen in the log - I had to disconnect the keyboard & the dongle multiple times.
BUT! I finally got to upload a Log.

Here it is. Hope you can get anything from it 
Thanks in advance!
Next steps until next advice:
- Setting up a Pi with OMV and SMB / NFS Share - so I can test the NFS Share function.
- Watch my Pi how its behaving with the fstab samba setup.
- Let him watch over USB until then.
Some more things that came up my mind:
We’re both “cooling” the Pi with simple heatsinks (no fans) and both use the RYDGES 2.5A 5V Power Supply.
