Fresh install of OS and MythTV on n43

Created 2007/09/05 – last revised 2008/01/06

I needed to upgrade MythTV to 0.20.2 due to the demise of Zap2It schedules, but I didn’t have another system which matched the hardware used on my MythTV PVR.  So I installed a spare 120GB EIDE and started from scratch to build another MythTV instance from scratch.  Once I was satisfied the new instance would pass the SAT (spouse approval test), I used LVM to move everything over to the 320GB SATA disk which currently contains the old (production) MythTV sw and configuration.

This describes that build and migration process. 

Hardware (n43):

Antec Fusion HTPC case

AMD Sempron processor (about 1.6GHz)
512MB memory – good enough for single tuner and OS
Hauppage PVR-350 standard definition capture card

Integrated on to mainboard:
Audio:
ALC883 PCM nVidia MCP51 controller – kernel module snd-hda-intel (high definition audio)
Video:
nVidia C51 – Quadro NVS 210S / GeForce 6150LE
nVidia EIDE and SATA controller – …

1. Install OS

Seems to be lots of hits on Fedora 7 and MythTV, as well the reading I’ve done on Fedora 7 seems to show it can be easily kept up to date (via yum) – and it has the OS clustering capabilities as part of the base now, which I’ll use when I split the current single system making it the back end and adding a silent (diskless) front end.

Downloaded and burnt Fedora 7 i386 DVD. For future options, extracted and burnt boot.iso … also see notes on how to install Fedora 7 via boot.iso and NFS. (notes to be added)

Disabled SATA hdd in BIOS (could have unplugged it, but easier to just disable via sw).
Used DVD drive in n43 to install Fedora 7 on the temporary EIDE drive.
Select packages for install:
MySQL Server
Web Server

See scripts for automated Fedora 7 OS setup and package install (setup1.shl, setup2.shl) (scripts to be added)

About 25 min off DVD for base load

Setup (first time boot):
Firewall – allow SSH and HTTP, otherwise no inbound services other than ESTABLISHED,RELATED are needed at this point. Will open MySQL and ICMP for monitoring purposes later. When this system becomes the MythTV backend, will have to add MythTV ports (see FAQ).
SELinux – disable, will add SE configuration at some future point.
NTP – use default Fedora 7 NTP service configuration, time sync is obviously very important (unless you don’t want your recordings to start/end at the right times).

MythTV seems to heavily use KDE, so although Gnome is default, may need to use KDE. I selected Gnome this time. And KDE this time. And RatPoison is a compact window manager which may be easier to configure for mythtv. Finally I’m using fvwm2 .. more on that later.

Update /etc/hosts
192.168.2.143 mythtv.networkforensics.org mythtv n43

Manually set the interface speed/duplex (gigabit interface doesn’t do well in autonegotiate – poor performance, but no interface errors). Will come back and setup an init script.
# ethtool -s eth0 speed 100 duplex full

Add ATrpms repository into yum configuration:
NOTE: other ATrpm yum configurations on the net don’t work!
– add the following into /etc/yum.conf
[atrpms]
name=Fedora Core $releasever – $basearch – ATrpms
baseurl=http://dl.atrpms.net/f$releasever-$basearch/atrpms/stable
gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms
gpgcheck=1

Import ATrpms key
# rpm –import http://ATrpms.net/RPM-GPG-KEY.atrpms

Disable ATrpms repository, so we only get mythtv packages from it:
– add the following to the atrpms section just added to the /etc/yum.conf:
enabled=0

Update the packages to current using the standard Fedora repositories

When following the Fedora / MythTV HOWTO (http://wilsonet.com/mythtv), they use variable KVER which is just uname -r

# echo “export KVER=\\`uname -r\\`” >> /etc/profile.d/kver.sh

Do yum upgrade to get latest kernel and system

# yum upgrade

464MB 265 packages

<odd>

Kernel panic during reboot after upgrade

Searched on “2.6.22 fedora 7 kernel panic noapic” – lots of suggestions but doing a single boot again, while interrupting the grub boot and adding noapic to the end of the kernel boot line seemed to fix it. Now the grub.conf looks like (note the vga=791 arg):

default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.22.4-65.fc7)
root (hd0,0)
kernel /vmlinuz-2.6.22.4-65.fc7 ro root=/dev/VolGroup00/LogVol00 rhgb quiet vga=791
initrd /initrd-2.6.22.4-65.fc7.img
title Fedora (2.6.21-1.3194.fc7)
root (hd0,0)
kernel /vmlinuz-2.6.21-1.3194.fc7 ro root=/dev/VolGroup00/LogVol00 rhgb quiet vga=791
initrd /initrd-2.6.21-1.3194.fc7.img

Add window manager fvwm here – comes from Fedora repo

# yum install fvwm2

2. No mouse cursor in Gnome

Seems the nVidia graphics are broken somehow. Must disable hardware cursor?

<URL>

ok add this line to your xorg.conf

Option “HWCursor” “off”

so it looks something like this

Code:

Section "Device"

  BoardName    "GeForce 6600/GeForce 6600 GT"

  BusID        "1:0:0"

  Driver       "nvidia"

  Identifier   "Device[0]"

  Option       "HWCursor" "off"

  Screen       0

  VendorName   "NVidia"

EndSection

logged out from Gnome, causes an X restart then the mouse cursor showed up properly.

3. Set Monitor and Resolution

In gnome, I manually set the monitor, it could not autodetect the Viewsonic Optiquest V75. Restarted X, had to set the resolution (it defaulted to way too high of a setting)

HOLD:

As per Fedora MythTV setup guide, install the nVidia drivers:

# yum -y install nvidia-graphics9755-kmdl-$KVER
# yum -y install nvidia-graphics9755-libs nvidia-graphics9755

Actually, this is done now by copying in a revised xorg.conf

[root@mythtv grub]# cat /etc/X11/xorg.conf.1024×768-monitor-only-V75-BEST

Turn off screen saver

Disable unnecessary services

services=”avahi pcps bluetooth”
for service in $services; do chkconfig $service off; service $service stop; done

avahi – DNS service discovery
pcps – smart card daemon
bluetooth

4. Set mysql to start on boot

chkconfig mysqld on

5. Start up MySQL

service mysqld start

6. Set MySQL root password

mysql –uroot

mysql> grant all on *.* to root@localhost identified by “rootpassword” with grant option;

mysql> grant all on *.* to root@n43 identified by ‘rootpassword’ with grant option;

7. Create MythTV database

Test out mysql connection, user, password

# mysql -uroot -prootpassword

mysql>

Run MythTV database setup

# mysql -uroot -prootpassword < /usr/share/mythtv/sql/mc.sql

/usr/share/mythtv/sql/mc.sql:
CREATE DATABASE if not exists mythconverg;
GRANT ALL ON mythconverg.* TO mythtv@localhost IDENTIFIED BY “mythtv”;
FLUSH PRIVILEGES;
GRANT CREATE TEMPORARY TABLES ON mythconverg.* TO mythtv@localhost
IDENTIFIED BY “mythtv”;
FLUSH PRIVILEGES;
ALTER DATABASE mythconverg DEFAULT CHARACTER SET latin1;

8. Install MythTV Suite

# yum –enable=atrpms install mythtv-suite

122 packages, 105MB

Create directory for recordings

# mkdir /storage/recordings

# chown mythtv:mythtv /storage/recordings

9. Install ivtv drivers and firmware for PVR-350

# yum –enable=atrpms install ivtv-firmware
# yum –enable=atrpms install ivtv-kmdl-$KVER

10. Update modprobe.conf to enable TV Out on PVR-350

# load ivtv-fb for PVR-350 output
install ivtv /sbin/modprobe –ignore-install ivtv; /sbin/modprobe ivtv-fb

Manually load ivtv

# /sbin/depmod -a
# /sbin/modprobe ivtv

Manually tried to load ivtv-fb – segfaulted … see the part of the howto on modifying grub boot loader…

We’re going to make little modification to the kernel boot line in your grub.conf file that should force the ivtv frame buffer to load on /dev/fb1, as well as allow the ivtv-fb module to be loaded and unloaded. Without doing this, unloading the ivtv-fb module would probably crash your system. To the end of all ‘kernel /vmlinuz…’ lines in /boot/grub/grub.conf, append ‘vga=791′, then reboot your system. This tells the kernel to load a frame buffer for your video card at 1024×768, 16-bit color. I use this all the time myself, simply so I can see more when I’m not in X. I’d always done this on my 350-equipped box without even thinking about it, which could explain some of why I’ve not run into some of the problems other folks have…

Note video device:

[root@mythtv ~]# ls -l /dev/video*

lrwxrwxrwx 1 root root 6 2007-09-09 18:17 /dev/video -> video0

crw——- 1 root root 81, 0 2007-09-09 18:17 /dev/video0

11. Test out PVR-350 TV Out

As per https://help.ubuntu.com/community/MythTV_Edgy_hardware_pvr-350_TV-out

Try to display the TV test pattern by putting the saa7127 module into test mode:

# /sbin/rmmod saa7127

# /sbin/modprobe saa7127 test_image=1

Works!

Resume normal operation:

# rmmod saa7127

# modprobe saa7127

Test video capture

# /usr/bin/v4l2-ctl -i 0

12. Manually compile ivtv module for X

Had to manually compile ivtv driver for x to enable tv out .. due to some 2.6.22 issue.

As per README in ivtv x driver package – must install xorg sdk to allow compile:

# yum install xorg-x11-server-sdk

Then compile the new ivtv xdriver:

# sh ./configure

# make

# make install

Copy into xorg directory:

# cp /usr/local/lib/xorg/modules/drivers/ivtv_drv.so /usr/lib/xorg/modules/drivers

if gdm failed, ps -ef , then kill it to restart

copy in new xorg.conf (with TV Out section) and do <ctrl><alt><backspace> to restart x server

[root@mythtv ~]# cat /etc/X11/xorg.conf.tvout

# XFree86 4 configuration created by pyxf86config

I found this simple set of directions to add in a base set of true

type fonts (which includes Ariel) to Fedora 7 and it solved the problem.

1. Open a Terminal and cd to a directory you can work in

2. Become root

3. Download the MS Core Fonts Smart Package File

wget http://corefonts.sourceforge.net/msttcorefonts-2.0-1.spec

4. Make sure that the rpm-build and cabextract packages are installed

yum install rpm-build cabextract

5. Build the Core Fonts package:

rpmbuild -ba msttcorefonts-2.0-1.spec

6. Install the Core Fonts package

rpm -Uvh /usr/src/redhat/RPMS/noarch/msttcorefonts-2.0-1.noarch.rpm

The web site I found this one was: http://www.fedorafaq.org/#installfonts

And get the kernel modules:

# yum –enable=atrpms install lirc-kmdl-2.6.22.4-65.fc7-0.8.3-70_cvs20070827.fc7

resulted in:

Dependency Installed: lirc-devices.noarch 0:0.8-4.fc7

Manual test:

# modprobe lirc_mceusb2

Update modprobe.conf to load LIRC

…

/dev/lirc was symlinked to /dev/lirc/0 (which is the PVR-350 …) so re-linked to /dev/lirc/1 and restarted lircd

# service lircd restart

then irw showed button presses!

Updated /etc/init.d/lircd to relink the /dev/lirc symlink to /dev/lirc/1

Get MythTV to use remote:

Copy lircrc file into ~mythtv/.mythtv/lircrc and ~mythtv/lircrc (no dots)

Install lirc kernel modules

NO yum –enable atrpms install lirc-kmdl-2.6.22.4-65.fc7

Had to uninstall all the modules I installed then re-install lirc 0.8.3 from atrpms

Migrate from 120GB disk back to 320GB SATA

2007/10/20 Fedora 7

Use LVM to move the data, including /root, swap and /storage

In BIOS, enable SATA drive, position as HDD #2 (120GB IDE as HDD #1)

Boot single user (interrupt grub, select first kernel <e>dit, select kernel spec line, <e>dit, add “single” on the end of the line, <b>oot the system (off the old IDE disk)

Display partition table for both drives just to be sure that the 320GB (new) disk is /dev/sbd and the current ‘production’ IDE disk is /dev/sda

# fdisk -l /dev/sda

# fdisk -l /dev/sdb

Zero out the partition table and MBR on the SATA disk as we had previously installed Fedora 7, and that data will confuse the migration process.

# dd if=/dev/zero of=/dev/sdb bs=1024k count=100

Partition new disk to add similar partition structure, including LVM partition

sdb1 100MB ext3 /boot (0×83)

sdb2 <the rest> LVM (0x8e)

Set the disk bootable (option a)

[root@mythtv ~]# fdisk -l /dev/sdb

Disk /dev/sdb: 250.0 GB, 250059350016 bytes

255 heads, 63 sectors/track, 30401 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System

/dev/sdb1 * 1 13 104391 83 Linux

/dev/sdb2 14 30401 244091610 8e Linux LVM

Zero out the LVM partition as we had already setup a fresh Fedora 7 install, and the LVM information will still be there (and called VolGroup00, it will confuse LVM on the old IDE disk)

# dd if=/dev/zero of=/dev/sdb2 bs=1024k count=100

Copy the /boot contents across:

# mkfs.ext3 /dev/sdb1

# mkdir /tmp/new

# mount /dev/sdb1 /tmp/new

# cd /boot

# find . –print | cpio –pmd /tmp/new

Now update (install) boot loader on new 320GB disk:

# mount /dev/sdb1 /tmp/new (if not still mounted)

# mv /tmp/new/grub/device.map /tmp/new/grub/device.map.old

# /sbin/grub-install /dev/sdb

# umount /tmp/new

Label this filesystem as /boot to match /etc/fstab:

# e2label /dev/sdb1 /boot

Now ‘create’ the new physical volume in LVM and display the pv’s to ensure all’s good:

# pvcreate /dev/sdb2
# pvdisplay

Add the new physical volume into the VolGroup00 volume group

# vgextend VolGroup00 /dev/sdb2

Move all the physical extents from the old IDE disk to the new SATA disk (this will tell lvm to move the physical extents from PV /dev/sda2 to some other free physical volume – the only other volume is the SATA disk we just added). Note this will take a LONG time and will display it’s progress:

# pvmove /dev/sda2

Remove the old disk:

# pvremove /dev/sda2

Power off and disconnect power to the old IDE disk, boot to ensure all comes up ok

Power off and remove IDE
