WARNING: you are attempting to use parted to operate on (resize) a file system.
parted's file system manipulation code is not as robust as what you'll find in
dedicated, file-system-specific packages like e2fsprogs.  We recommend
you use parted only to manipulate partition tables, whenever possible.
Support for performing most operations on most types of file systems
will be removed in an upcoming release.
End?  [214MB]?
Error: Could not detect file system.
Oh.. then delete partition manually and create a new one. Don't forget
to set prep and boot flags on it.

Hi,
i made a new install without LVM.
grub2-mkconfig -o /boot/grub2/grub.conf
grub2-install --force --recheck --no-nvram /dev/sda1
170+1 records in
170+1 records out
Installation finished. No error reported.
But now:
PReP-BOOT : Unable to load full PReP image.
Loaded bf8000  out of cb00000  bytes.

It seems your PReP partition is quite big.
parted /dev/sda resize 1 8M
grub2-install /dev/sda1

Hello,
i have installed openSuSE 13.1 on a IBM Power7 LPAR.
The Problem is that the bootloader can not installed.
I installed the openSuSE on LVM (with multipath).
Yaboot (ybin) ist not available.
We have yaboot wrapped by lilo script. (lilo package)
...
Is it possible to get it work with grub2 ?
Or is there another bootloader to boot ?
# grub2-install
You shouls specify PReP partition to install to. Like grub2-install
/dev/sda1
...
Path `/boot/grub2' is not readable by GRUB on boot. Installation is impossible. Aborting.
# grub2-mkconfig -o /boot/grub2/grub.cfg
#vgdisplay
