Live boot images

• /cscf-adm/src/fetch_ubuntu_releases 14.04 will update all of the latest 14.04 releases
  • Any number of version numbers can be listed - they will all be updated
  • calls pxe_liveboot_nfs service to remount and export new images

PXE Ubuntu Installers

• /cscf-adm/src/fetch_ubuntu_installers - creates a PXE installer for all liveboot images
• This is only of use for an install from scratch

RIP PXE node imaging old method

• We used RIP PXE boot to image the original nodes on himrod - the suggested new was is to use clonezilla
• Use iDRac web console for node
  • firefox --no-remote ilom-himrod-1
  • login with root and 2013 cscf-adm passwd
• Network boot the node in pxe mode: reboot_once_pxe
• Choose RIPLinuX 13.7
  • RIPLinuX 13.7 64Bit with Kernel from himrod version vmlinuz...
• login root - no password
• setup network dhcpcd
• run clone script: distroy_and_clone
  • This reformats /dev/sda partitions and copies /himrod-node (from himrod) to / on the node
• cd /mnt/sda1/ubuntu-scripts
• chroot and bind required filesystems into /mnt/sda1:
  • ./mnntpart /dev/sda1 - ignore any bind mount errors - a few are for other versions of ubuntu
• verify networking, ie: ping www.yahoo.com
• fix grub
  • cd /ubuntu-scripts
  • ./grubfix
    • yes remove grub - we purge and reinstall
    • boot */dev/sda1
