Post subject: | Installation Questions (mostly partitioning and LVM related) |
Hi, As my prior post said, I am coming from FC4+MythTV sytem to Knoppmyth. I have now had a chance to read (noth throughly) the Installation Instruction WiKi. Here are my questions/concerns
I think that is enough for now. I am assuming I ought to use the Manual Install right? I am no expert in Linux and I have never seen anything other than an old Knoppix and FC2/3 and 4. But haven't actively used Linux. I can do OK in UNIX if I was given instructions (I am in IT you know). |

I don't think this setting even exists anymore... If it does, just set it to the normal place for recordings. dvpatel wrote: the automated scripts are only able to handle 255GB storage. How to increase that 255GB limit? Any help on creating an LVM of 400GB to utilize both my disks would be appreciated. That's obsolete information LVM2 (which is what Cecil provides) makes this a nonissue. dvpatel wrote: Can the system be configured to use BOTH the VGA and the TV as monitors.
Yeah, but you probably won't like the results. Search fro "twinview" for more info. |

Post subject: | HELP |
OK. So, I moved around my hardware. Dumped a CD ROM, moved a HDD as slave onto the secondary channel and made the 40GB Master on Primary Channel. Drive Configuration is as follows: Primary Master: Seagate 40GB PATA Primary Slave: WD 200GB PATA Secodary Master: Pioneer 106D DVD-RW Secondary Slave: WD 200GB PATA The Seagate has a 41MB Dell Utility Partition. It shows up as /dev/hda1. How do I use Auto Install and not blow that partition away. I wasted over an hour moving my drives around so that I could dump the RAID card and the Audigy (mostly to get the second tuner in). I chickened out at the Auto Install Warning where it said it will wipe my drive. I tried manual install but I could not cough up the courage to blow away my original partitions. The reason: Fedora needs/likes a /boot partition of about 100MB. I dunno if I need to blow that away or not. Someone please help me. All I want is: 40GB OS drive and the 400GB /myth partition. If possible, please include step by step instructions. Thanks |

What is it you're trying to do? Why do you can about Fedora if you want 40 gigs for the OS and 400 gigs for /myth? You need to provide specific details/questions if you want specific answers. |

I don't care about the Fedora Partitions. What I was asking was Fedora has a 100MB /boot partition which is not there in the KnoppMyth partition map in the wiki. So, I was confused. Then, in the Wiki, in the manual step information, I am not sure how to go about proceeding after the blow away the partitions. I have read posts on here of folks saying that the install did not install in the correct partitions. All I want is to preserve that 41MB /dev/hda1 partition. The 2 200GB drives are showing up as LVMs. Do, I delete those too or leave them alone and then follow the LVM steps? Thanks |

Do a manual install. Create two partitions on hda. One will be /, the other your swap. Delete any partitions on the 2 200s and create 1 (entire drive) on each. After rebooting, simply follow the LVM how-to (should be as simple as create_lvm.sh /dev/hdb1 /dev/hdd1, format the /dev/vg/myth w/ which ever fs you'd like.... mount /myth) and continue alone the with the installation...). BTW: I personally would not put a CD-ROM and a hard drive on the same bus... |

OK. Thanks a lot. I will try to do that today and report back. We are expecting company today so, I might not be able to do it today itself. cecil wrote: BTW: I personally would not put a CD-ROM and a hard drive on the same bus...
Can you please enlighten me regarding that statement. I have used HDDs on the same bus as CD-ROM but always in Windows. Does Linux behave differently? Does it affect DMA is that why you said that? Thanks |

At least historically, the slowest device on an IDE channel limited the speed for the whole channel. Since optical drives are generally slower than hard drives you could end up throttling your HD severely. Also with early burners, which were very sensitive to buffer under flow issues, you didn't want anything else on the channel if you could help it. These issues are less severe with modern hardware but I would still be cautious about doing it. |

Post subject: | LVM Howto |
Maybe the LVM script will work fine for you, but I've always installed MythTV without telling it about all my other drives and then handled the LVM for /myth separately. (I have three drives totalling 820GB, with almost all of that devoted to the /myth LVM.) I find the following LVM Howto extremely clear and step-by-step for newbies, but maybe it's just me: http://www.linuxhomenetworking.com/linux-adv/lvm.htm Hopefully that helps someone else too. |
