 Posted: Fri May 05, 2017 1:51 pm Post subject: [solved] I am stuck with install of softraid/lvm at grub |
 |
|
I started off with https://forums.gentoo.org/viewtopic-t-1061792-highlight-.html but as there is already quite much listing in it making it uneasy to read and I give it another slightly different go, I have opened this thread.
I have started with Gentoo LiveDVD and followed the handbook to install a system with /boot on a softraid partition and the rest on lvm2 partitions.
My partitioning:
| Code: | livecd ~ # lsblk

I entered chroot with:
| Code: | cp -L /etc/resolv.conf /mnt/gentoo/etc && \

mount --rbind /run/ /mnt/gentoo/run && \

and did:

I did some extra installation of software.
However, trying to install grub with
| Code: | (chroot) livecd / # grub-install /dev/sda
Installing for i386-pc platform.
grub-install: error: failed to get canonical path of `aufs'. |
Some research on the net made me make a df which then showed me my boot on a device simply "aufs".
| Code: |
(chroot) livecd / # df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/vg_sata-lv_root_2 41022688 15516332 24441396 39% /

/dev/sde4 5448780 1124224 4028060 22% /run/media/gentoo/Gentoo-amd64 |
The same source on the net suggests to remount /boot from within the chroot. So I did
| Code: | | (chroot) livecd / # umount /boot/ |
Mounting again, however, was not possible.
| Code: |
(chroot) livecd / # mount /boot/
mount: /dev/md127 is already mounted or /boot busy
/dev/md127 is already mounted on /boot |
It showed that /boot seemed to be fine then.
| Code: | (chroot) livecd / # df /boot
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/md127 154501 8986 134052 7% /boot
|
Trying to install grub again fails but with
| Code: | (chroot) livecd / # grub-install /dev/sda
Installing for i386-pc platform.
grub-install: error: disk `md127' not found. |
Does somebody know how to handle this?

partition table is msdos?
maybe missing useflags for grub? (device mapper)
not sure where aufs for /boot comes from. 
Edit: Oh, you bind the livedvd /boot into your chroot? that can't possibly be right  you only do bind for proc sys dev |

Dooo, just got aware that I was having /boot of the LiveDVD rebound to /mnt/gentoo/boot/!!! After a reboot grub-install worked flawlessly.
