Post subject: | Running backend on non-dedicated machine? |
I'm tired of the size/sound of my combined FE/BE machine. So I'm planning on splitting the system and changing to a small, diskless, QUIET frontend. Initially I was going to set up a dedicated BE machine, but it seems wasteful to have both a normal "desktop" machine and a MythTV backend machine running all the time. Has anybody had any experience running the backend on a non-dedicated machine -- one that's also used for "normal" stuff (SW development, web browsing, e-mail, etc.)? My tuner is network-attached (HDHR), so all the backend is doing is shoveling bytes back and forth from between the network and the disk drive -- that doesn't require much CPU at all, and I'll probably keep the recordings on a dedicated drive. Sadly, that means the backend won't be running KM any more... -- Grant |

I've read about folks doing it, but I can't point you to a specific post or website. I wonder if you can make use of a virtual machine running KM/LinHES? In principal, I see no reason why that wouldn't work. What host O/S are you wanting to use, Linux or Winblows? |

Winblows? Gentoo Linux. There's a Gentoo package for MythTV, and I have heard from one gentoo user who runs his MythTV backend on his general-purpose desktop. He had problems with recordings until he put the MythTV data on a dedicated disk. He was using a PVR-250 which has fairly modest disk i/o requirements, so I imagine it would have been even worse recording an ATSC HD program stream. I was planning on a dedicated MythTV drive anyway, so I'm going to give it a try in a couple weeks. |

The VM is probably easy compared to setting up mythtv, mysql, apache, etc. on a Linux box from scratch, no? |

I have to agree with Graysky. The point of KM or LinHES is that is a simple install yet feature rich environment. In the backend alone setting up mythweb will be easier just using stock KM vs figuring out all the magical incantations in your favourite distro. I run my master backend in a VMWare guest which simplified my life. I describe this in a few places but perhaps to the point in: http://knoppmyth.net/phpBB2/viewtopic.p ... c&start=26 Before I went to VM I was installing mythtv from atrpms on to my main server which is CentOS based. It was simply more work and upgrades were trickier and riskier. C |

That was a combined FE/BE box using a PVR-350 which required several additional drivers, and mythtv had to be built from sources because binary packages for the CPU I was using weren't available. It took most of a Sunday, but it wasn't particularly difficult -- except for the part where you use the mythv GUI for configuring stuff (and you can get around much of that by using SQL commands to change the settings instead of have to guess which off-screen buttons are highlighted). This time, MySQL and Apache are already set up, and mythv isn't going to require any device drivers or kernel modules: no video card drivers, no capture card drivers, no lirc drivers/configs, no Xv/XvMC, etc. It should be pretty straight-forward.
