Updating to the new PXE Shell OS #

This is for SynergyCP 4.x and older. The new PXE Shell OS is included by default in Synergy 5.0+ installations.

• On your File Server(s), copy your existing /shell/ directory to something like /shell-old/
• Replace the two files in the shell directory with the following:
  • https://install.synergycp.com/bm/pxe-file-storage/files/srv/tftp/shell/sdisk64.img
  • https://install.synergycp.com/bm/pxe-file-storage/files/srv/tftp/shell/vm64
  • Note that if you update your file servers, it contains this new shell OS image. Any old scripts are compatible with the new shell OS.

Replace your Format Quick template with the following:

if [ -f "/synergy/version" ]; then
    version=`cat /synergy/version`
    echo "Found Version $version Shell OS"
    for disk in $(find /dev/sd[a-z])
    do
        echo "wiping $disk"
        blkdiscard $disk
        wipefs -a -f $disk
    done
    for disk in $(find /dev/nvme[0-9]n[1-9])
    do
        echo "wiping $disk"
        nvme format -f $disk
        wipefs -a -f $disk
    done
else
    echo "Running on old Shell OS or no version file"
    echo "Falling back to old wipe method"
    for disk in $(find /dev/sd[a-z] /dev/nvme[0-9]n[1-9])
    do
        dd if=/dev/zero of=$disk bs=512 seek=$(( $(blockdev --getsz $disk) - 1024 )) count=1024
        dd bs=512 count=63 if=/dev/zero of=$disk
    done
fi
