 Posted: Thu Jun 10, 2004 1:45 am Post subject: 'emerge grub' fails |
 |
|
I've been having trouble getting my grub from a Mandrake installation (see my other post: http://forums.gentoo.org/viewtopic.php?t=183668) and I think it has less to do with the actual configuration than I thought. I tried installing grub because I read online (somewhere!) that you still have to have the system files for grub installed on the disk from which you want to boot. However, when I try 'emerge grub', I get the following error after a lot of compilation:
| Code: | >>> Merging sys-boot/grub-0.94-r1 to /
cat: /proc/mounts: No such file or directory
cat: /proc/mounts: No such file or directory
*
* Cannot automatically mount your /boot partition.
* Your boot partition has to be mounted rw before the installation
* can continue. grub needs to install important files there.
*
!!! ERROR: sys-boot/grub-0.94-r1 failed.
!!! Function mount-boot_mount_boot_partition, Line 53, Exitcode 0
!!! Please mount your /boot partition manually!
!!! FAILED preinst: 1
bash-2.05b# mount
<SNIP>
/dev/hdb5 on /boot type reiserfs (rw,noatime,notail) |
My /boot seems mounted to me... what's wrong here? |

This looks not like a grub specific problem, but like a procfs problem.
What does say if you invoke it in a shell?

if you are trying to do this on the Live CD try ,
| Code: |
mount -t proc /proc /mnt/gentoo/proc
|
before you chroot.
Seems to make things a little happier

| Code: | localhost / # mount
/dev/hdb7 on / type ReiserFS (rw,noatime)
none on /proc type proc (rw)
none on /dev/shm type tmpfs (rw)
/dev/hdb5 on /boot type reiserfs (rw,noatime,notail)
localhost / # cat /proc/mounts
cat: /proc/mounts: No such file or directory |
I'm doing this in Mandrake, installing Gentoo on my second HD and chroot'ing in from a terminal window.
What does that 'no such file' mean? |

Oh, sorry 
So /proc is mounted and only /proc/mounts is missing? You have files in /proc, right? Strange. |

Nope, I have nothing in /proc. (!!!)
| Code: | localhost / # ls /proc/
localhost / # |

Es kool.
Hopefully you're doing the emerga AFTER chrooting? Otherwise the system will be very confused.
And there should be no need to install grub in Gentoo AND mdk, assuming they use the same boot part. Just add Gentoo to grub.conf. |

OK, one step further. Did you try to mount the procfs (see yodis post)? |

I'm not mounting /proc beforehand because I'm not using the LiveCD. I already have a /proc mounted for my Mandrake system, so I mount the chroot'ed /proc afterwards, as you see in my post above. Is that bad?
Quantumstate, good to know about the unnecessity of installing grub, but it seems I have bigger fish to fry now, believe you me.  Thanks. |

| I don't think, that works. You should mount the proc filesystem to /mnt/gentoo/proc (not to /proc again) before chrooting. Just as yodi wrote. Thats independed from the live cd. |

| So, did you succeed in emerging grub. By the way, the alternative to mounting proc is to mount /boot manually. |

Yes, that did it; I forgot to post back after trying again. As for booting, I'll post back (in a different thread) after I try that if I still need help. Thanks! |

i have this same error...in the install guide it says to do
| Code: | # mkdir /mnt/gentoo/proc
# mount -t proc none /mnt/gentoo/proc
|
which i did. emerge grub gives the same error message originally listed in this thread, but i tried
| Code: | | umount /mnt/gentoo/proc |
and then
| Code: |
mount -t proc /proc /mnt/gentoo/proc
|
as suggested earlier...neither thing worked, and i continue to get the same error...if these things aren't working, what should I try, and how would i mount the boot partition manually? |

| I don't really know, but it seems like it may be a good idea to start a new thread on this... just my opinion, anyway. <rant>It always bugs me when people will ask a question at the end of an already-answered thread.</rant> |
