MythTV using NAS (on a via ) using Gigabit ethernet.

I've posted a couple of times regarding setting up MythTV using NAS
and I just wanted to get peoples input on a system I was thinking of
doing and whether it would work...

1 x NAS for storage, mysql, apache etc (using FreeeNAS and a dual or
quad nic system)
Using one of the following boards with a 1.5Ghz processor:
http://via.com.tw/en/products/mainboards/motherboards.jsp?motherboard_id=610
http://via.com.tw/en/products/mainboards/motherboards.jsp?motherboard_id=570

1 x Master backend/fronend for recording/watching
2 x Frontends

The way I was thinking of setting up the backend was using two NICs
one for recording and mysql and one for everything else, and on the
NAS box have one NIC for recording and one for everything else as
well, this way the writing to the disk is done on its own gigabit
connection.

Am I right in thinking that because the sql db is on the NAS box that
the frontend would not need to see a master server up and running?

I would prefer a system that is on 24x7 but I want something that is
low powered, quite quiet and can be located somewhere out of the way
and I'm hoping this is feasible.

I was also thinking the same thing, but it is not true. It needs
mythbackend for something (no idea what for).

But you could install a master backend without tuners on your NAS
machine, and use your other backend as a slave backend. Your NAS is
always online -> your master backend is online.

The backend is what serves up your recorded files. It has to be on.
IIRC, the master backend also has to have at least one tuner.

Really? Here is one more idea :) :
-> I read somewhere on the -dev list that there is some kind of
virtual tuner which can be set in mythtv. Devs use it for testing

Dummy tuner:

Cold this be used on the master backend?

I have my master backend / mysql database running in a virtual machine
with no tuners defined. I do not however, use the master backend override
for streaming.

I believe this to be incorrect.

Sorry. The backend has to be available for the frontend to connect to AND
has to have at least one tuner.

The last time this question came up, I thought the answer was that the
backend doesn't actually need a tuner as such, but running it without a
tuner is a "not supported configuration".

Some things also don't seem to need a backend running, like MythVideo
(although it complains about no backend the videos it can access still
play).

so, it looks like I should forget NAS and use the via board as a
master backend and use a slave backend for recordings, but have the
recordings saved to the master backend.. that just leaves the question
of can you have a master backend with no tuners or can you setup a
virtual tuner that does nothing?

Maybe this is the anwser..

This is incorrect : I have a MB without any tuner and I works like a
charm. My slave wakes up and shutdown it self without any issue and I
can connect with my separate frontend without having the slave on.
My MB is running on a via C2 at 500 Mhz with 256 Mo of ram. It also
runs nfs, mysql, mediatomb and samba without using swap.

It is correct. You are running an unsupported configuration. Just
because it works for you doesn't mean it won't break at some point. :)

Re: MythTV using NAS (on a via ) using Gigabit ethernet. [In reply to]

so... if I set up a myth backend that has a network/dummy tuner and a
slave that has two dvb-t cards, will that work? I won't get any
issues such as incorrect disk space etc?

This would make for an interesting set-up if it works.. MythTV as a
FreeNAS module or a minimyth backend.. that would be cool.

I was doing this for a while as well, for commercial flagging and
transcoding. No tuners, but the backend process is required to
flag/code. Would be really nifty if those two could stand along
without a backend, but for now, that's what's required.

That's an unsupported configuration. I'm happy it's working for you,
but if one day it should stop, you'll have to fix it yourself.

Your wish has been granted. ;)
You should be running mythjobqueue instead of mythbackend.

I don't mean to sound like an arse, but I'm quite confused. What
exactly would depend on the master-backend having a tuner? Isn't a
master backend with a busy tuner and a slave backend with a free tuner
is the same a master backend with a free tuner resource wise?

[Yes I know, not supported, tested, or anything like that..]

The backend goes through a initialization step where it loads capture
card information, sets them to their starting channels and makes sure
the cards are working (as much as it can check that. It not-so-
gracefully fails these things when there is no capture card defined
and throws errors in the log. It might be easy for someone who would
really like this configuration to write code to support it, but it
seems that everyone who writes the code just decides to not run the
backend instead since there's no reason to run it if you don't have a
capture card.

I'm not claiming to know all he specifics of how the backend code
looks. This is just what I have gathered from looking at my own logs
and errors when I've used a database without any capture card
configuration, etc...
