[mythtv-users] Master Backend Override Confusion

[dfleming at swings.2y.net]

I just added a third tuner to my system and while I have been using 
myth for some time now, this darn "Master Backend Override" switch is 
confusing me.


I have 3 PCs all with 1 tuner card:

System1 - Master.  Frontend/Backend, has large disk allowing NFS.

System2 - Slave. Diskless Frontend/Backend connects to Master via NFS.

System3 - Slave. Diskless Frontend/Backend connects to Master via NFS.


>From what I understand, the "Backend" that created the recording also 
streams the given recording to Frontends local and remote.  In the event 
that the "Backend" that created the recording is unavailable, the 
"Master Backend" will look for the file and, if found, stream the file 
to Frontends if "Master Backend Override" is enabled.

If everything is correct so far, here are my questions:

Should "Master Backend Override" only be enabled on the "Master"?

Are there any ways to minimize network traffic?

I would rather have my Master system stream all recordings.  Otherwise 
it sounds possible that a Slave could read the file via NFS, then stream 
the file to a remote Frontend thus doubling the network traffic for 
streaming 1 recording.

Thanks for your help.
