Installing grub2 fails due to labels conflicts?

SanskritFritz · 2014-03-24 11:36:50

I had a working arch setup on /dev/sda with the following setup:

/dev/sda1 /boot
/dev/sda4 /

Then I bought a new disk and installed a new archlinux onto LUKS from the previous working system. The new setup is the following:

/dev/sdb1 /boot
/dev/sdb2 /dev/mapper/cryptroot /

However I'm still booting from the old sda1 grub-legacy, I just edited the menu.lst to point to the new sdb1 /boot. Now I want to wipe the old disk because I want to encrypt it too. So I installed grub and issued the command:

root@HomeC # grub-install /dev/sdb 
Installing for i386-pc platform.
grub-install: warning: Attempting to install GRUB to a disk with multiple partition labels.  This is not supported yet..
grub-install: warning: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and their use is discouraged..
grub-install: error: will not proceed with blocklists.

I don't know it there are multiple labels or not, and my google-fu didn't reveal anything useful (tried this for example: http://slopjong.de/2013/10/11/attemptin … n-labels/). My labels are like this:

lrwxrwxrwx 1 root root 10 2014-03-24 10:43 bakoboot -> ../../sdb1
lrwxrwxrwx 1 root root  9 2014-03-24 11:16 bakodisk -> ../../sdb
lrwxrwxrwx 1 root root 10 2014-03-24 10:43 sda1boot -> ../../sda1
lrwxrwxrwx 1 root root 10 2014-03-24 10:43 sda4ext4 -> ../../sda4

Well there is a suspicious entry, because I don't know how I labelled sdb itself as bakodisk, I probably wanted to label sdb2. Could that be the issue? How do I solve this problem? Also I tried to remove the label with

e2label /dev/sdb ""

but that didn't help either.

Is the partition table of /dev/sdb GPT or MBR ?

Maybe worth quoting the result of fdisk -l:

Well, I simply solved the problem by moving /boot to sda1. I just had to edit the menu.lst and fstab. Done.
