1README for mondo/mindi usage with PXE
2
3mondorescue now supports the possibility to deploy mondo-images using the Pre eXecution Environment (PXE) standard.
4As this README only focusses on the mondorescue part, please read how to do Linux deployments with pxelinux on http://syslinux.zytor.com/pxe.php
5
6To use it, please do the following on your deployment server:
7
8Add the following line to your default file:
9mondo
10        kernel vmlinuz-mondo
11        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=(ipadr:netmask:broadcast:gateway|dhcp)] [ping=#] ...
12
13The initrd and kernel file come rom the first bootable media
14created by mondoarchive. To get them, please issue:
15
16# mount /path/to/mondorescue-1.iso /mnt/cdrom -o loop
17# cp -a /mnt/cdrom/vmlinuz /var/tftpboot/vmlinuz-mondo
18# cp -a /mnt/cdrom/initrd.img /var/tftpboot/initrd-mondo
19# umount /mnt/cdrom
20
21Thus 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.
22(You need to have backup your data using the NFS option of mondoarchive)
23
24If 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.
25Without 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.
26
27During 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. 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.
