 Posted: Sun Feb 27, 2005 1:08 am Post subject: After power outage Gentoo freezes on Boot |
 |
|
Hi, there was a power outage while I was on vacation, and when I arrived home I found my Gentoo webserver turned-off.
When I booted it up it would boot normally, but stop after it said "Detected PS2 port" or something like that.
I've been working on this webserver for a few weeks now preparing it as an intranet webserver for a client. Normally I would just format the drive and start from scratch, but I literally do not have the time to prepare the system again as the deadline for the project is the 1st of March.
Hoping to solve the problem with one command I simply loaded the webserver with a liveCD, chrooted into my server, and then ran "genkernal all", as I had done previously when compiling the original kernel.
Since then, Gentoo doesn't even boot at all.
It says: "Loading Gentoo..........................."
And then the cursor is on the next line blinking, but that's it.
Any ideas on what caused this problem?

What file system were you running? XFS can lead to corrupted file systems if you have power outages (happened to me, though it took a few before the system became unusable).

/dev/hda1 = ext2

Guess that wasn't the case. Did you think of trying to recreate the boot partition and then re-compiling and re-installing the kernel? That shouldn't take very long.

Yeah, that's why I ran "genkernel all" again.. which I presume would reinstall the kernel again.
Do I need to re-partition the boot partition? |

I don't use genkernel, so I don't know whether it automatically installs the kernel or not, you're best off looking at the docs to see whether that's the case. In any event, if I were you I'd first try just creating a new kernel and using that. If that doesn't work, try re-creating the boot partition. Have you thought of scanning it for errors using one of the file system tools? If you do this, boot into the livecd first.
Best,
Alex |

Yeah, I am going to manually configure the kernel now and see what happens.[/code] |

Good luck... it seems intimidating, but, in all honesty, it's not hard at all. If in doubt just use the help feature and follow the advice  .
Best,

Well, I don't think I need DECnet support so I just removed module support for it and am compiling the kernel again. |

I'm not sure, really. Given that it's looking for a 2.4 version of the kernel and I assume you're compiling a 2.6 kernel, my best guess is that /usr/src/linux isn't pointing to the directory that has the correct version of the kernel.
Check by using ls -la /usr/src/linux and see whether the directory it points to matches up with the directory containing the kernel you wish to compile. If it doesn't, just do the following:
| Code: |
rm /usr/src/linux
ln -s [directory with source code] linux
|
Then go into the linux directory and start the compilation process.
Did you read the documentation on configuring and compiling kernels thoroughly? If you follow that step-by-step you ought to be alright.

I just noticed that, so you might want to ignore my previous email.
Might I ask why you're compiling a 2.4 kernel (if that's what you are doing?)

| i just used "emerge gentoo-sources" to get the most stable kernel. I've read elsewhere that although 2.6 is "good", 2.4 is still recommended for production purposes. |

Hey, thanks for all your help Alex.
The new kernel works great, but there is another strange problem now:
During the boot sequence it "checks" the root filesystem, but it can't find the file /etc/devfs.d
But it asks me to enter the root password to enter "maintanence" mode, but what is strange is that when I do enter, I'm inside my root fs. So, I have no idea what's wrong with it, but it's just too unstable to really use.
And as I'm truly approaching my deadline I've decided to simply rent a webhost and get to scripting today.
Again, thanks for your help, and I can at least say that I've learned quite a bit through this disaster
