Library cleared if nfs path becomes unavailable

[lordvader 2]

Hey,

Quite regularly my nfs paths become temporarily unavailble. During these instances, emby decides to clear the library (and then notifies trakt). Is there a way to stop it doing so?

I'm running 4.9.0.0 beta in a docker container, on an ubuntu host.

Here's a log snippet:

Hi there, please attach the complete emby server log file. Thanks.

Here you go

embyserver-63844968079.txt

So to the server it looked like /media/TV Shows was empty. That's why it cleared everything out.

Can the nfs mount configuration be changed so that it throws an error instead? When Emby Server gets an error back, then it won't delete anything.
