=== TerraChurners ==

The "TerraChurners" are the lab machines at the labs at Duke and in Aarhus.

The machines have 3 1TB disks. SATA0,SATA1 and SATA2

This is how they were installed:

1. Enter BIOS:
   • Make sure SATA{0,1} is managed by the RAID system and SATA2 is on, but _not_ managed by the BIOS.
2. Enter RAID system
   • Add SATA{0,1] to a RAID0 setup, striped and with optimized block size.
3. Boot the installation CD (which is Ubuntu Gutsy Gibbon x64)
   • You may have to use the boot trick described  here
4. Open a terminal and do the following:
   • Run "sudo parted /dev/sdc" and run the following commands:
   • print
   • Make sure all partitions are removed (print shouldn't list anything) and run the following in parted:
   • mkpart primary ntfs 0GB 750GB
   • mkpart extended 750GB -1s
   • mkpart logical ext3 750GB 995GB
   • mkpart logical linux-swap 995GB -1s

     Here is how it looks:
     ubuntu@ubuntu:~$ sudo parted /dev/sdc
     GNU Parted 1.7.1
     Using /dev/sdc

     (parted) print

     (parted) mkpart primary ntfs 0GB 750GB                                    
     (parted) mkpart extended 750GB -1s                                        
     (parted) mkpart logical ext3 750GB 995GB
     (parted) mkpart logical linux-swap 995GB -1s                              
     (parted) print                                                            
     
     Disk /dev/sdc: 1000GB
     Sector size (logical/physical): 512B/512B
     Partition Table: msdos
     
     Number  Start   End     Size    Type      File system  Flags
      1      32.3kB  750GB   750GB   primary                     
      2      750GB   1000GB  250GB   extended               lba  
      5      750GB   995GB   245GB   logical   ext3              
      6      995GB   1000GB  5201MB  logical                     
     
     (parted)           
     

4. Start the installation, use manual partitioning:
   • For sdc1 specify /media/windows as mount point
   • For sdc2 specify / as mount point and use as "ext3"
   • For sdc3 specify "swap"
5. Create a (temporary) user for yourself
6. REMEMBER: to give the computer a decent host name.
7. REMEMBER: In "ready to install dialog" select (hd2) as the disk for the boot loader.
8. edit /boot/grub/menu.lst to set groot to (hd0,4).
   • Do NOT remove the comment # sign
   • run update-grub
9. Open a terminal and run:
   • apt-get update
   • apt-get upgrade
10. You should reboot after point 10.
11. Open a terminal and run
    • apt-get install dmraid openssh-server

Known issues:

• The machines bbq and grits in Aarhus show a black screen when booting from Ubuntu-Recovery/InstallCD.

The current workaround is the following: When booting from CD, select an item like "Start or Install Ubuntu", but before pressing Enter, press F6 and exchange the part "quiet splash" with "nosplash".
