Grad PC Documentation

• The GRAD PC TWIKI page documents what an image has, post install steps and problem solving for each image
  • Please use this resource when creating new images

Basic Overview

1. ) Connect your system to ASIMOV vlan 420
2. ) Set you machine to UEFI PXE boot
   • Consult: https://cs.uwaterloo.ca/twiki/view/CF/UEFI
     • Make sure your system has PXE boot ROM enabled and ipv4 network stack enable, network boot order UEFI first and legacy second
     • Note: when you UEFI PXE boot on Asimov you will see UEFI in menu title a after network booting - or - BIOS if UEFI booting failed
     • Be sure to pick the correct UEFI partition for booting after imaging (done in the BIOS) as imaging changes these.
3. ) PXE boot the machine* - typically F12 or F8 boot option (may require PXE boot enabled in BIOS)
4. ) Use either
   • clonezilla NFS Live menu to create a new image on ASIMOV
   • The remaining entries do a fully automated prompt-less restore - or semi-manual- - overwrites all partitions without asking
     • If you hit one by mistake you have about a minute to hit the power and avoid erasing your system.

Create a new image

1. ) Always remember to Document your image
2. ) PXE boot your computer on vlan 420 ASIMOV
   • • IMPORTANT NOTE - if you have two network interfaces connect them BOTH - even if one is disabled - to avoid a bug in network detection*
   • F8 - or F12 should give you boot options to do this - you may have to enable the network boot rom option in your BIOS
   • Computer Boot Menu - Pick Your Network Card
     • You may have to enable the Network Boot ROM in the BIOS
   • IMAGE - Pick CLonzilla NFS
   • IMAGE - Pick LIVE-RW
   • IMAGE - CLonezilla Loading
   • IMAGE - Pick Start_CLonezilla
   • IMAGE - Pick device - image work with disks
   • IMAGE - SKIP - Use existing /home/partimage
   • IMAGE - ENTER to continue
   • IMAGE - savedisk Save_Local_disk_as_an_image
   • IMAGE - Input Image name
   • IMAGE - Choose Local disk as source
   • IMAGE - Do you want to check or repair file systems before imaging? Optional
   • IMAGE - Do you want to check if the image is restorable ? - optional
   • IMAGE - Check Saved Image - optional
   • IMAGE - Do Not Encrypt Drive
   • IMAGE - Clonezilla Command Line Summary Enter to Continue
   • IMAGE - Are you Sure You want to continue ?
   • IMAGE - Imaging in Progress
   • Notes:
     • Skip mounting any partitions - /coregroup/image_drop is automatically mounted Read/Write
     • Use device image - then *pick default options for everything * - except for the image name (check file systems, verify image, etc)
3. ) Move the image into its correct home under /*coregroup/images/core - or /coregroup/images/research based on its end use.
   • Notes:
     • The the path /coregroup/image_drop is the only Read/Write NFS path on ASIMOV - this is to protect the images from accidental overwrite.
4. ) Run the make_clonezilla script - see next section

make_clonezilla script - create menus for all Clonezilla images found on asimov

1. )_Log into ASIMOV - become root
2. ) Run the script: make_clonezilla
   • This rebuilds the PXE boot menus for clonezilla adding any image it finds

Restore the image

• References
  • GRAD PC Image notes are documented here

1. ) PXE boot your computer on vlan 420 ASIMOV
   • F8 - or F12 should give you boot options to do this - you may have to enable the network boot rom option in your BIOS
   • IMAGE - Computer boot menu
   • IMAGE - PXE boot in progess
2. ) Restore Clonzilla image
   • Go to "Clonzilla image" in the menu PXE Boot Page
   • Generally go to "Clonzilla NFS_MANUAL_p6p2 on 192.168.0.1.." Select Manual
   • Search for the right image, (can be tricky) Find Image
   • Wait for image to boot up (Depending on image, this can take a while) Wait
3. ) Follow these steps through the Clonzilla screen
   • Start Clonzilla Start Clonzilla
   • Disk-image Disk Image
   • skip Skip
   • Press enter continue Continue
   • Expert Expert mode
   • Restoreddisk Restored Disk
   • Re-select the image Select Image
   • Sda (or sdb to image 2nd hard drive) Choose Drive
   • Use arrow keys to go to ICDS, press space then enter ICDS
   • -k1 create table proportionally -k1
   • -scr, do not check drive Skip Check
   • Generally shutdown when done, as you will likely not come back to it for a while Choose Finish Option
   • Press (y + enter) twice to confirm and start the imaging Confirm

Some Window-Ubuntu dual boot images do not have "fast startup" disabled in Windows 10. You will notice this when the computer only soft reboots when attempt to shutdown on Windows. Go to Control Panel -> Power Options -> What Powers button do -> Change settings that are currently unavaliable -> uncheck fast startup -> Save changes to fix this.

Clonezilla syslinux and PXE options

Kernel Options

• • https://www.kernel.org/doc/Documentation/kernel-parameters.txt

Clonzilla Parameters

• • http://clonezilla.org/fine-print-live-doc.php?path=./clonezilla-live/doc/99_Misc/00_live-boot-parameters.doc#00_live-boot-parameters.doc
  • ocs_prerun, ocs_prerun1, ocs_prerun2... is intended for running a command before an operation of saving/restoring an image or cloning disk/partition is started. E.g. ocs_prerun="/live/image/myscript.sh". If you have more commands to run, you can assign them in the order: ocs_prerun=..., ocs_prerun1=..., ocs_prerun2=.... If more than 10 parameters, remember to use ocs_prerun01, ocs_prerun02..., ocs_prerun11 to make it in order.
• ocs_live_batch="yes" - non-interactive
• ocs_daemonon, ocs_daemonoff, ocs_numlk, ocs_capslk.

Ex. for the first 2 parameters, ocs_daemonon="ssh", then ssh service will be turned on when booting. For the last 2 parameters, use "on" or "off", e.g. ocs_numlk=on to turn on numberlock when booting.

• locales=en_US.UTF-8 - preset language
• keyboard-layouts=NONE (won't change the default layout, which is US keyboard)

ocs-sr options

• • http://allthatnetwork.blogspot.ca/2012/10/clonezilla-ocs-sr-options.html
• -g, install grub in MBR of disk with GRUB partition
  • auth - autodetect partition
• e1, --change-geometry NTFS-BOOT-PARTITION Force to change the CHS (cylinders, heads, sectors) value of NTFS boot partitoin after image is restored. NTFS-BOOT-PARTITION can be one of "/dev/hda1", "/dev/hda2"... or "auto" ("auto" will let clonezilla detect the NTFS boot partition automatically)
• -e2, --load-geometry-from-edd Force to use the CHS (cylinders, heads, sectors) from EDD (Enhanced Disk Device) when creating partition table by sfdisk
• -b, -batch, --batch (DANGEROUS!) Run program in batch mode, i.e. without any prompt or wait for pressing enter key.
• -c, --confirm Wait for confirmation before saving or restoring
• j2, --clone-hidden-data Use dd to clone the image of the data between MBR
• -p, --postaction [choose|poweroff|reboot|command|CMD]
