The packages for libparted and kpartx don't have the patches for using device-mapper (multipath/LVM) on 4k-sector disks (generally: 'non 512-byte sector disks')
This causes the number of sectors of each device-mapper partition to be 1/8th (512/4096) of that expected.
These 3 errors were identified:
1) Partition sizes on multipath/LVM are 1/8th of the intended size
2) The filesystem on the underlying device is not-accessible (only in the dm mapped device)
3) grub-install fails w/ 'Unknown filesystem'
The 2 patches attached contains upstream patches from parted and multipath-tools, and fix the issues (the installation finishes without errors and the system boots). |

QEMU/KVM
--------
If you don't have 4k-sector disks handy :)
An example for multipath on 4k-sector disks, with 2 underlying devices:
$ qemu-img create -f raw disk.img 16g
$ qemu-system-ppc64 -enable-kvm \
-nographic -nodefaults \
-monitor stdio -serial pty \
-M pseries -m 2G \
-net nic -net user \
-drive media=cdrom,file=../../iso/vivid-server-ppc64el.iso.0408 \
\
-drive file=disk.img,if=none,cache=none,serial=my-serial,id=drive0 \
-drive file=disk.img,if=none,cache=none,serial=my-serial,id=drive1 \
-device scsi-hd,physical_block_size=4096,logical_block_size=4096,drive=drive0 \
-device scsi-hd,physical_block_size=4096,logical_block_size=4096,drive=drive1 |
