Use live knoppix to edit fstab on hda1
Background: This problem is with a Fedora 5 installation, on a machine with previously one
hard drive. The machine and install has never given any problems in the past year. I installed an additional data disk which I can see but cannot write to, I now assume because the permissions are set incorrectly. What I did to cause the problem: I have changed the /etc/fstab file and now the machine will not boot. I can boot the machine with a Knoppix 5.1.1 Live DVD, however I do not understand how to mount my original hda1, and work on the fstab file. I kept a virgin copy in the /etc folder, so I believe it is a matter of renaming the fstab.old file to fstab. I have figured out how to set a password to be able to log on as root, but I seem not to understand how to open my original hard drive, ie where mangled /etc/fstab resides. Can anyone point me to a good article on this so I get an understanding of how to use a rescue disk in a case like this. Thank you for any direction you can provide mg92865 |
Once you get in a terminal (as root):
fdisk -l to see all the drives and partitions mkdir /mnt/somename to make a mount point mount /dev/hda1 /mnt/somename to mount the partition to the mountpoint cd /mnt/somename AND ls to see the contents (replace "somename" and "hda1" with appropriate entries) To edit fstab: nano etc/fstab (Not no leading "/"--you want the etc/fstab that is on /mnt/somename (AKA /dev/hda1)) If nano is not installed, then kedit, kwrite, or whatever editor IS there. |
It is best to use the distribution's install disc, for Fedora, try this:
1: Boot from Fedora Core Linux 1st CD or DVD: Set BIOS to boot from CD/DVD rom. At boot: prompt type command linux rescue Code:
boot: linux rescue Code:
# chroot /mnt/sysimage From a live CD with /dev/sda2 as an example for your Fedora / partition, mount the device in read/write by first un-mounting it, assuming the live CD sees it as /media/sda2, and the file system is ext3: Code:
# umount /media/sda2 |
Thank you for your input. At this point my results were not successful.
Junior Hacker - The problem here is that is still a problem with the extra data drive that I added (hdb1 and hdb2), and this stops the install per your directions, only offering me the option to reboot. This happend with the drive present, and again after I pulled the data drive, so something in the configuration files must not like the way I have the hdb1 and hdb2 set up. Quote:

Although your instructions seem simple, it is not within my skillset yet. I will review the man commands for your suggestions a bit more to see if I can follow this. All help is appreciated, as it is how I have actually learned how to use and install Linux. Thank you again for your efforts. I will likely wait a day or two to see if other suggestions appear. If not, I will pull the hard drives, install a small spare, reinstall, and look for a way to recover any files that need to be backed up. mg92865 Quote:

Is it possible for you to post the output of the command: fdisk -l here, that is if you can boot Knoppix with the second drive installed and run that command. You can highlight/copy the output from the terminal and paste it in kwrite editor and save it to a USB flash drive or floppy with a name ending in .rtf which will not be changed around when viewing the file from Wordpad in Windows. Than we can give assistance in writing the proper configuration in /etc/fstab of the Linux.
Also post the /etc/fstab file would be a great help. |
OK, this is the results of the fdisk command. If you wanted to see the contents of my (not knoppix created fstab) fstab, I will need help in determining how to do that. If there is anything I can provide, please ask. Thank you again for your assistance.
