3README for mondo/mrmini usage on ia64
4
5Linux distributions on ia64 uses a different file table format than on i386, called GPT instead of MBR. The fdisk command used by mrmini/mondo to determine all aspects related to the disc hasn't been adapted yet to handle GPT. Only the parted command is able to do it.
6
7So a perl script called parted2fdisk.pl was written that will take as input all the order that mrmini/mondo pass to fdisk, translate them to be given to parted and print the result in fdisk format. So this is a filter allowing fdisk replacement. It's only used on ia64. On other archs, parted2fdisk is a link to fdisk.
8
9Thus mrmini/mondo launched by root will pass all their call to parted2fdisk instead of the real fdisk, and be able to support the GPT format. It will call fdisk and parted for its work.
10
11To get it on the system to restore, please do the following as root:
12
13make -f Makefile.parted2fdisk
14make -f Makefile.parted2fdisk install
15mv rootfs/sbin/parted2fdisk-ia64 rootfs/sbin/parted2fdisk
16
17This will produce a binary version that will be used by mondorestore during the restoration process on ia64 to handle the GPT format. (Note again that on ia32 parte2fdisk is in fact a link to fdisk to avoid any compatibility issue)
18
19The install.sh script will setup everything correctly for you.
20
21Note that parted2fdisk.pl supports currently only the -l and -s options as well as the commands p,n,d,w,t,a,q
22
23On Itanium systems you won't generally find an installed isolinux.bin file which is required by mrmini to create the bootable images. You'll generally have to take an i386 package for your distribution and install it on your itanium system so that you provide the required missing file.
24
25On SLES 10, fdisk is nor provided anymore. You'll have to rebuild the util-linux package by desactivating fdisk removal in the spec file.
26
27Please report any problem around that tool to bruno@mondorescue.org
