Supported Scenarios

The goal of this document is to have a single source of information which scenarios are supported by yast2-bootloader.

bootloaders

• grub2

• grub2-efi

• only for UEFI boot

• only with GPT (see bug)

• none

Partition table

• DOS partition table

• GPT

• requires bios_boot partition if stage1 will be on disk

• DASD

• only s390x

storage configuration

• software RAID

• /boot cannot be on RAID unless it is RAID1

• cannot have stage1 on MD RAID1 ( so no /boot on RAID1 )

• LVM

• /boot cannot be encrypted (not bootloader limitation see bug)

• multipath

• Device mapper

• local hard disk (including USB/ieee1394)

• local (hardware) RAID array of any type

• BIOS-RAID (handled via DM-RAID or MD RAID)

• iSCSI server with persistent IP address / disk identification

• NFSv3,v4 share on server with fixed IP address

Architectures

• x86

• x86_64

• ppc64(le and be)

• only GRUB2

• there must be at least one PReP partition which size must not exceed 8MB (see fate)

• s390x

• /boot/zipl must be on ext fs ( unless upgraded from working zipl configuration )

• only GRUB2

Stage1 locations

• MBR of disk where is /boot

• MBR of identical disks in MD RAID if it contains /boot fate

• /boot

• extended partition

• /boot has to be on a logical partition
