 Posted: Fri Jan 02, 2004 9:35 am Post subject: I messed up my fstab |
 |
|
| I'm pretty much a newbie and because of that I wrote over my fstab and a few other files. Anyway I noticed that and decided to correct it so that my system would still work. I tried to look that the files would be as they should. The problem is that I put 2 numbers in wrong places in fstab and now my system doesn't work. I get some kind of error and then I can log in using root password to fix this error. The problem is that to fix it I would have to edit fstab but it just says that it's read-only. I tried to look an answer but I couldn't find anything. Could somebody please help me correct this. And please give detailed instructions or point me to them since I can't undestand complicated thing about gentoo or linux just yet. Thank you. |

and chroot to the gentoo system!

Sorry to hear this.
Just some friendly advice.
I keep a printed handwritten journal for sensitive info like my fstab. I have messed up my fstab in the past and my journal allowed me to recover it.
Why handwritten ? Because when I do mess things up, softcopies are usually gone but I can still look at my paper journal. |

| Yeah that's a really good idea. I wrote down everything I did during the install in case I'd have to do it again. I had my fstab written down but I didn't check it as many times as I should have since I made a mistake. It's actually a good thing I had to reinstall since I had my hard disk partitioned so that I wouldn't have been able to use almoust half of it at all. I have no idea why I did that in the first place. |

I'd actually recommend that you make a backup copy of your entire
/etc directory tree and store it on a floppy or CD. It is not very large
and contains a lot of important config information which might be hard
to recover if you loose it. I do this one or twice every month.  |

More detailed instructions how to repair:
You take the gentoo install cd (you could also use knoppix, that would be different) and boot form it like you did during the install. After it booted, you mount your root partition (the one gentoo was installed on, probably /dev/hda3) to /mnt/gentoo/ by using this command:
| Code: | | mount /dev/hda3 /mnt/gentoo |
Now you use nano to edit the fstab by using this command:
| Code: | | nano -w /mnt/gentoo/etc/fstab |
You correct the settings and save the file. After that, you unmount the root partition again:
Now reboot (shutdown -r now or simply reboot) and you should be set.
I hope you know what to change in the fstab. Otherwise, read about it (google "linux fstab").
EDIT: I agree with didl, just put something like cp -R /etc /root/etc_bkp into your /etc/conf.d/local.start and you are on the safe side.

I agree with keeping a backup of "/etc", that's the kind of things I do too.
However I still keep a handwritten or printed out copy of vital stuff for those occasions when I have messed up thing very badly. For example it has happen to me to mess up my usb settings so that I couldn't read my usb zip drive where I keep my backups.
Also, writing things down forces me to think about what I write and learn about things.
Anyways, it's a good idea to keep backups and by all means do, but sometimes you can still get stuck kind of like using the network to report that the network is down.
Note: You can still loose your paper journal, your cat could eat it etc...  |
