 Posted: Thu Nov 28, 2013 2:02 am Post subject: grub2-mkconfig -o /boot/grub/grub.cfg doesn't complete/hangs |
 |
|
As background I am trying to solve this problem: https://forums.gentoo.org/viewtopic-t-976176-highlight-.html
I am not able to boot my system at all. It is LUKS over LVM and dual boot Win7. When booting it throws a real root balh blah not recognized but the path to real_root it indicates is correct.
At the moment I am stuck because | Code: | | grub2-mkconfig -o /boot/grub/grub.cfg |
hangs and never completes. I ran it once to stdout to see where it is getting stuck and it appears to be at | Quote: | | ### BEGIN /etc/grub.d/30_os-prober ### |
Any ideas? |

You can try to install the os-prober package if not. The /etc/grub.d/30_os-prober script use the os-prober command. An other thing you can do is to render the /etc/grub.d/30_os-prober script not executable
| Code: | | chmod 0644 /etc/grub.d/30_os-prober |
and see if grub2-mkconfig is completing. You will not have any entry other than the ones to boot Gentoo this way, but you have a chance to first boot Gentoo to resolv from it the other problems you have.

OK. I reinstalled the os-prober package and that didn't fix it. Still stalls on 30_os-prober.
I did the chmod and grub2-mkconfig successfully completed. But I still can't boot my Gentoo. (I think this is a separate issue I have to resolve).
I re-installed the the ntfs3g package thinking that maybe that got borked somehow but that didn't fix anything. chmod'ed back to original permissions and it still stalls on 30_os-prober so clearly something is not right with that particular script. Any other ideas?
Also even though you did say it I spaced out. Now I can't boot into my Win7partition because grub2-mkconfig rewrote grub without that entry. How do I get it back?
Thanks. |

So part of my problem is that I had a corrupted grub.cfg file. It had lots of junk data in it "$" that I assume rendered it useless when loaded. I cleaned it up and was able to boot and then run grub2-mkconfig which completed successfully.
I went back to my chroot environment to see if I could duplicate the problem and the behavior indeed was the same. The script runs until it hits 30-OS_Prober and then stalls out. It is reproducible every time and if I turn of the executable bit on 30-OS it will run.
Is this a bug I need to report someplace? Is it a problem with the chroot environment? |
