Fedora Booting problem

[Saketram]

Hello,

I am using Fedora Core 5 (2.6.15-1.2054_FC5). I got Fedora hanged while I was working in Fedora Operating System, then I rebooted.
Since then Fedora does boot. The message displayed while booting are given below. After these message system hangs.

=================================================
Uncompressing Linux.... Ok, booting the kernel
Red Hat nash version 5.0.32 starting

Here are some more messages/trails.

Using Fedora Rescue disk, I booted, but it could not find/mount sysimage of my Linux paritions.

# fdisk -l
Disk /dev/hda: 15.3 GB, ......
16 heads, 63 sectors..., 29805 cylinders

Dev Id System
/dev/hda1 b W95 FAT32
/dev/hda2 83 Linux
/dev/hda3 8e Linux LVM


I manually mounted hda1 and hda2, but could not mount hda3.
By the following statement
# mount /dev/hda3 /mnt/fos -t ext3 -o rw
...... Invalid argument

# fsck.ext3 /dev/hda3
fsck.ext3 1.38 (30-Jun-2005)
Couldnt' find ext2 superblock, trying backup blocks.
fsck.ext3: Bad magic number in super-block while trying to open /dev/hda3

# e2fsck -b 8193 /dev/hda3
e2fsck 1.38 (30-Jun-2005)
e2fsck: Bad magic number in super-block while trying top open /dev/hda3

I do not know what to do further, and waiting for your suggestion.

Thanking you.

hda3 is an LVM pv-vg with 2 LV's on it (/, and swap)

cat /etc/fstab to see mount format (and maybe mtab)

Do you see the hda5 message?

This means you had another swap partition there when you installed FC5 and it made it the primary swap file and also sized it up for the hibernate file.
Now it is gone (so remove it from fstab.) (a swap in the vg00 will be used for paging and swapping but I'm not sure what will happen to hibernate.)

That could be the soruce of the other messages or they could be another problem.

Thank you SlowJet, you should be absolutely observed the correct situation.

Because a day ago, I removed a hard disk (it was hdb) and keep it using on another computer by formating and installing another operating system.

Now I can not get it back with this system.
And as I could not get the Linux drive, how can I edit fstab to remove this hdb.

Please tell what to do now to recover the Operating system.

Just repartition and install fedora again and take care about some swap partitions that will be marked from fedora.
I had 2 swap partitions on my fedora and the second one was raid array... but the fedora used them both.

Is there anyother trials to try towards recovering my Fedora Operating System?? I have lot of files in the Linux Operating system disk, I want to recover them atleast.

So please give instruction on recovering.
Thank you.

I assumed you would use the rescue or liveCD.
Edit text files with nano.
If you can do a yum update from there, do that also. (Those messages may be the dm raid issue and / or stata drives?)
FC5 out of the box is buggy depending on your hardware and installation, but is working good with all the updates.

Finally the following link enabled me to recover my Fedora.
