  /dev/md0 is the / partition
  /dev/md0 is the / partition for Ubuntu 10.10 Server; I used the Server edition and then added the desktop software, it was the easiest way to get it to install on a software RAID 0 configuration.
  /dev/md1 will be a RAW partition for a virtual machine.

Okay. So I have to install Windows 7 natively because performance of ESRI ArcGIS 10 under VirtualBox totally sucks. To work under Windows the RevoDrive would have to be configured in a fake raid (BIOS) configuration making it unusable in Linux and defeating TRIM. So I can't use the RevoDrive in Windows.
It took 3 or 4 tries to get both Windows 7 and Ubuntu living happily on the same system. It was a wild dance.  


I installed Windows7 on the Raptor drive, now I need to get Linux going again.

This gives me access to the raw partitions from a VirtualBox machine, in theory I can boot them directly. I can add the raw partitions to an existing Ubuntu machine to examine them. '''I have to run VirtualBox as Administrator.'''
Note also you have to run VirtualBox as Administrator too to use raw partitions.
 
It also took me many long hours of booting and adjusting settings in the Linux grub configuration trying to get the RevoDrive to work as / partition until I gave up and installed Ubuntu Server and it worked on first try.


I add the raw disk partitions via the Virtual Media Manager, then add the vmdk to the virtual machine Storage settings and start it. The drive is visible as /dev/sdb now. Ta-da!

Raven is a desktop computer.

History

Fall 2010 upgrade with RevoDrive 120GB SSD and 2TB Caviar Black

2010 Nov 17 -- OH! Raven changed so MUCH today. 3 way boot setup; Windows 7 Ultimate, Ubuntu 10.10 Desktop, and Ubuntu 10.10 Server on SSD

Fall 2009 upgrade with Patriot 32GB SSD Spring 2009 - initial build

Hardware

  • Shuttle SX48P2 Deluxe case and motherboard
  • Intel Core 2 Duo CPU E8500 @ 3.16GHz
  • 8GB DDR3 1066 memory

Drives

  • WD Velociraptor 300, WDC WD3000HLFS-01G6U3, FwRev=04.04V05, s/n WD-WXL608035725

(which replaced this one that died under warranty WD Raptor 10K RPM SATA, WDC WD3000HLFS-01G6U0, s/n WD-WXLY08084357)

  • OCZ REVODRIVE 120GB, FwRev=1.20, s/n OCZ-GYY134R2861260WR Nov 2010
  • Caviar Black 2TB, WDC WD2001FASS-00W2B0, FwRev=05.01D05, s/n WD-WMAY00310595 Nov 2010

I used to use this, it's not installed anywhere right now.

  • Patriot "Warp V2" 32 GB SSD, SATA I/II, 2.5" s/n MK050943085B30039 Fall 2009

The case includes a fingerprint scanner, bluetooth and a wifi card. I pulled the wifi card (which has a USB interface) and use it somewhere else now.

Software

It is currently running 10.10 Ubuntu.
I often use it to run VirtualBox so that I can use ESRI ArcGIS.

Drive configuration

See also SSD optimizations

RevoDrive is at /dev/sda and /dev/sdb 

/dev/md0 is the / partition for Ubuntu 10.10 Server; I used the Server edition and then added the desktop software, it was the easiest way to get it to install on a software RAID 0 configuration.

The wild dance of Windows 7

It took 3 or 4 tries to get both Windows 7 and Ubuntu living happily on the same system. It was a wild dance.

Okay. So I have to install Windows 7 natively because performance of ESRI ArcGIS 10 under VirtualBox sucks. To work under Windows the RevoDrive would have to be configured in a fake raid (BIOS) configuration making it unusable in Linux and defeating TRIM. So I can't (won't) use the RevoDrive in Windows.

Linux will be given the entire RevoDrive.

At some point the system stopped booting from my Linux USB stick. It keeps stopping with an error and leaving me at the initramfs prompt. It turned out I had to type 'exit' (twice) and then it would boot just fine.

At another turn, someone (Windows 7 installer I think) overwrote the partition table on the 2.0 TB drive, effectively wiping my home partition. I was unhappy with this! When the operating systems were sorted out, I was VERY glad that I documented the partitions above, I was able to recreate the partition table and recover everything that I thought I had lost.

I tried using VirtualBox under Windows 7 to access raw partitions with limited success. Of note, I must run the command shell (cygwin bash) as Administrator to get access to the drives.

VBoxManage.exe internalcommands listpartitions -rawdisk '\\.\PhysicalDrive0'

gives appropriate results (no sharing errors.)

Note also you have to run VirtualBox as Administrator too to use raw partitions.
