This is likely a newbie question, but I’m going to be adding to my combo BE/FE and trying to wrap my mind around the architecture of it all. I’ve been reading the wiki and here and I think I end up with more questions then I had before… But let me start here.

First. How does Myth handle multiple BEs with multiple PVR cards and storage.



Does the recording from the MBE Air2PC ‘float’ over to the SBE? Will it force the storage on the local hdd (MBE) even if this means deleting newer ‘expiring’ recordings?

On the above example can all hdds be used to their maximum limit or only what might ‘fit’ completely on the drive. ie do all the drive space combine to make 1 big drive or partition?

On the above example, lets add a HDHomerun to the network. Where will it’s recordings be held?

TIA

As far as I'm aware, the storage will remain with the box the tuner is defined on. So, autoexpire will kick in on MBE.... You have to define the HDHR on a BE, it doesn't matter that it is on your network.

So the tuner is 'married' to the storage in it's box by default?

So then with the above example it would be best to add the HDHR to the BE with larger drives and hdd expandability. Correct?

It would be cool though to be able to 'pool' all BE drives into one big drive, writable by any tuner in any BE. But I guess the network would really take a beating, and other downsides too.

Just trying to figure out where and how to expand.

Thanks for the links. I have been reading more on this and the Storage Groups. It's sounding interesting.
