This page is a checklist for ntk, so that he remembers what to bring with him on the next on-site visit (or future on-site visits, for purchases).\r

 * Philips screwdriver\r
 * 2nd new hard drive\r
 * Burned RIP CD (from [http://www.tux.org/pub/people/kent-robotti/looplinux/rip/RIPLinux-2.9.iso])\r
 * Burned Debian Etch install CD\r
 * Netra needs to be mounted using the appropriate screws.  The Netra apparently does not require rails.\r
 * 9V+ type round adapter power cable for the new KVM switch\r
\r
Here is the plan for salvaging mire.\r
\r
 * Boot off the RIP CD.\r
  * If without RIP CD but with Knoppix, boot using this cheat-code: {{{knoppix-txt 3}}}  This should use {{{vga=normal}}} as a kernel parameter and boot into runlevel 3, command line only.  The point is to allow VNC to function properly as using the framebuffer may cause display issues with VNC.\r
 * Mount /dev/sda1 on /mnt (remember, this is the old /dev/sdb, when it is the only drive in the machine).\r
 * mwolson will:\r
   1. selectively copy things off of /etc onto deleuze (he will use git for this to clone his existing /etc repository, which can ensure that the contents are not corrupt)\r
   2. save the output of df, fdisk -l /dev/sda and dpkg -l\r
   3. copy the entire /etc directory to deleuze (for reference, in case mwolson missed something important in the earlier copying run)\r
   4. fsck /dev/sda*\r
 * Turn machine off, take out the hard drive, put in one new hard drive only, put the Debian Etch install CD in the CD drive.\r
 * Install Debian on the new drive, and boot from it.\r
   * Run bonnie++ (preferable) or dd to stress test the new HD and io subsystem, before wasting time installing too many other packages and configuring, etc.  Watch for errors during test.\r
     * bonnie -d /test/ -s 0.1 -n 1 -r 252 -u root\r
     * bonnie -d /test/ -s 0.1 -n 10 -r 252 -u root\r
   * Start copying over saved settings and packages to it.\r
   * ntk is free to leave at this point if he wants.\r
   * If the machine stays up, and does not lock up for a day or two:\r
     * We will assume that both of the old hard drives were bad, instead of just the old /dev/sda.\r
     * We will install the second hard drive.\r
     * We will bind the two hard drives together via RAID.\r
   * Otherwise, if the machine does lock up:\r
     * Obviously something else is wrong.\r
     * Look into various hardware we can try to replace, if there is some sort of SCSI card.\r
     * If the motherboard is bad, we will probably have to scrap mire, unless someone has other plans.\r
