3README for mondo/mindi usage with PXE
4
5mondorescue now supports the possibility to deploy mondo-images using the Pre eXecution Environment (PXE) standard.
6As this README only focusses on the mondorescue part, please read how to do Linux deployments with pxelinux on http://syslinux.zytor.com/pxe.php
7
8To use it, please do the following on your deployment server:
9
10Add the following line to your default file:
11label mondo
12        kernel vmlinuz-mondo
13        append initrd=initrd-mondo load_ramdisk=1 prompt_ramdisk=0 ramdisk_size=36864 rw root=/dev/ram iso_mode acpi=off apm=off devfs=nomount exec-shield=0 pxe [prefix="machine"] [ipconf=(ipdev:ipadr:netmask:broadcast:gateway|ipdev:dhcp)] [ping=#] ...
14
15ipdev is the device name (e.g. eth2)
16ipadr is the IP Address (e.g. 192.168.1.1)
17netmask is the Netmask (e.g. 255.255.255.0)
18broadcast is the Network broadcast (e.g. 192.168.1.255)
19gateway is the default gateway (e.g. 192.168.1.254)
20dhcp is a keyword. Using it will provide all the previous 4 values to activate the LAN interface.
21
22The initrd and kernel file come rom the first bootable media
23created by mondoarchive. To get them, please issue:
24
25# mount /path/to/mondorescue-1.iso /mnt/cdrom -o loop
26# cp -a /mnt/cdrom/vmlinuz /var/tftpboot/vmlinuz-mondo
27# cp -a /mnt/cdrom/initrd.img /var/tftpboot/initrd-mondo
28# umount /mnt/cdrom
29
30Thus the PXE ROM will boot mondo's kernel and mondo's initrd in memory and will append all the right configuration options (as you find in isolinux.cfg on the first bootable media) to which you need to add the keyword pxe.
31(You need to have backup your data using the NFS option of mondoarchive)
32
33If you used the -p option of mondoarchive, you may specify the real name of mondo images to use during restore. To do that use prefix=machine on the initrd line, after the pxe keyword, to load the ISO images saved with -p machine.
34Without prefix keyword, the name of the images used during archiving with the -p option will be used (they may differ). If -p wasn't used then the name mondorescue-1.iso, ... will be used.
35
36During boot mondorestore will start your NFS configuration and mount mondo's content from the network rather than from a physical media. You may alter the IP configuration stored from the original machine by passing the ipconf option describing respectively the IP address, netmask, broadcast and default gateway you want to setup for the machine, separated by ':'. Or alternatively, you may specify the dhcp keyword so that a DHCP request is made to get those information. In the 2 cases, you have to mention on which physical interface those parameters should apply. On some configurations, you may also want to increase the number of ping queries made before the NFS mount, which is of 3 by default, using the ping option and give the number you want.
