User:Esev/LinuxMCE Install Notes

Install Core/Hybrid

I think the kernel that ships with 0810 is too old for my hardware. Several devices need updated drivers. These drivers need to be placed onto a USB drive before beginning. You can view all the hardware for my setup on the LinuxMCE Setup page.

Boot the Snapshot DVD

These instructions were created for 0810 snapshot 23326. When booting from the DVD, change the kernel options to include "all_generic_ide" http://ubuntuforums.org/showpost.php?p=5436513&postcount=7

Create four partitions

1. 500MB ext3 for /boot
2. 4GB swap
3. 200GB ext3 for /
4. Rest of the drive XFS for /home

First Boot

Get the primary network card (eth0) working

 # Using a USB drive, copy the drivers for r8168, r8169, e1000, and hid to /root/drivers
 # extract, compile, and install the r8168 driver
 depmod -a /lib/modules/`uname -r`/kernel/drivers/net/r8168.ko
 rmmod r8169
 modprobe r8168
 /etc/init.d/networking restart

Install sshd so I can complete the installation from the comfort of my couch

 apt-get update
 apt-get install openssh-server

More driver installs

 # Replace the buggy r8169 module so it doesn't incorrectly auto detect my primary network card
   make
   cp r8169.ko /lib/modules/`uname -r`/kernel/drivers/net/
   depmod -a /lib/modules/`uname -r`/kernel/drivers/net/r8169.ko
 # Install the driver for the secondary network card (eth1) (e1000e driver)
   cd src && make install
   modprobe e1000e
 # Install the updated HID driver to support the Gyration_GYR4101US remote
   make
   cp hid.ko /lib/modules/`uname -r`/kernel/drivers/hid/
   depmod -a /lib/modules/`uname -r`/kernel/drivers/hid/hid.ko
 # Rebuild initramfs
   echo "r8168" >> /etc/initramfs-tools/modules
   update-initramfs -uvk `uname -r` | tee ~/updateinit.txt

Setup a RAID 1 across both drives

First install mdadm

 apt-get install mdadm

Then follow the directions here making the changes noted below.

 # /dev/md0 is sd[ab]1 - /boot
   mdadm -C /dev/md0 -n2 -l1 -e1 missing /dev/sdb1
   mke2fs -j -L boot /dev/md0 
 # /dev/md1 is sd[ab]5 - swap
   mdadm -C /dev/md1 -n2 -l1 -e1 missing /dev/sdb5
   mkswap -L swap /dev/md1
 # /dev/md2 is sd[ab]6 - /
   mdadm -C /dev/md2 -n2 -l1 -e1 missing /dev/sdb6
   mke2fs -j -L root /dev/md2
 # /dev/md3 is sd[ab]7 - /home
   mdadm -C /dev/md3 -n2 -l1 -e1 missing /dev/sdb7
   mkfs.xfs -f -l size=64m -d agcount=4 -i attr=2,maxpct=5 -L home /dev/md3

Inside the /dev/md2 chroot, replace /etc/fstab with

 LABEL=root /               ext3    relatime,errors=remount-ro 0       1
 LABEL=boot /boot           ext3    relatime                   0       2
 LABEL=home /home           xfs     relatime,allocsize=512m    0       2
 LABEL=swap none            swap    sw                         0       0

Use the LABEL=root in the grub kernel arguments too

 title           Ubuntu 8.10, kernel 2.6.27-17-generic - drive 1
 root            (hd0,0)
 kernel          /vmlinuz-2.6.27-17-generic root=LABEL=root ro quiet splash                               
 initrd          /initrd.img-2.6.27-17-generic
 quiet
 
 title           Ubuntu 8.10, kernel 2.6.27-17-generic - drive 2
 root            (hd1,0)
 kernel          /vmlinuz-2.6.27-17-generic root=LABEL=root ro quiet splash
 initrd          /initrd.img-2.6.27-17-generic
 quiet

Adding /dev/sda to the RAID array takes around three hours to complete on my 1TB drives
