Mounting duplicate Linux partitions

rridler · 04-21-2004, 06:47 PM

I recently had my Red Hat 9.0 Linux box crash due to a power outage (before I bought a battery backup). It had a large drive (160GB) holding the OS, Samba, ProFTP and Apache.
I have rebuilt an other smaller drive (4.3GB) with the OS, Samba, ProFTP and Apache.
I want to mount the old drive to be able to access the files that I have stored on it.
I am getting a message stating that there is a duplicate partion and I am unable to mount it.

What can I do?

So the new drive is the primary master, and fstab automatically mounts the partitions listed within it, correct? If so, the original/old drive would then need to be a slave or secondary drive - where is it? Are you trying to mount any of its partitions to the same mountpoint as those on the (new) primary drive? Can you post a copy of your fstab? -- J.W.

RH uses partition labels for ID in the fstab file. Your getting an error because now you have multiple partitions with the same label.

You can use tune2fs to change the partition lablels. You can modify the fstab file and grub file to use the device id i..e /dev/hda for each partition instead of labels.

Is there a prefered order of commands or sequence of events that I should use?
Should I boot to a floopy first and change the labels on the 160GB drive first, or boot to the 4.3 GB drive as master and the 160Gb drive as slave to make the label changes?

Any suggestions?

I would boot the installer CD to rescue mode but since I do not run Redhat someone else might have a better idea.

Here is a copy of my FSTAB file.
Any suggestion of how to reconfigure it would be of great help.

LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
/dev/hde3 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0

Change the label=/ to /dev/hdex where x is the partition ID. If you do not know how the drive is partitioned then look at the output of
fdisk -l /dev/hde (that is a small L)

You need to be logged in as root. Also post the output of /etc/grub.conf.

Why is "/etc/grub.conf" highlighted?

I changed the volume label in /etc/fstab & /etc/grub.conf and rebooted with the 4.3 Gb drive as the master and the 160Gb drive as the slave (The 4.3Gb drive will boot fine as single drive).
I am still unable to mount the 160Gb drive because there it is still showing that there is a duplicate mount point label.

What am I doing wrong?

Can any one help me out?
There are files that I need to have access too.
