Harddrive reorganisation problem [solved]

[jethro]

Hi everybody,

 

I devided one physical hard drive in two parts, the first part contains one partition for my Windows installation. The second part contains my Mandriva 2007 installation and one partition which I can use in both Windows and Mandriva. When I created this last partition after the installation of Mandriva 2007 things went wrong. This is the situation before I created the extra partition.

 

1 - empty (sda5)

2 - / (sda6)

3 - swap (sda7)

4 - /home (sda8)

 

This is how thing look after I created the OS-SWAP partition.

1 - OS-SWAP (FAT32)

2 - / (sda5)

3 - swap (sda6)

4 - /home (sda7)

 

 

After I created the extra partition (the OS-SWAP) using Mandriva, Mandriva said I had to run the "restore boatloader" option from the rescue mode of the install DVD because the drive numbers are changed (sda6 -> sda5, sda7 -> sda6, sda8 -> sda7). I first tried booting into Mandriva without doing this which resulted in a kernel panic, because something went wrong with the mounting of the drives. After I ran the "restore boatloader" thing it still went wrong the same way. Am I doing something wrong here? I am not sure, but perhaps I also have to modify fstab, but I am not sure if this is the way to go and I do not want to mess things up even more.

 

I hope someone around here can tell what to do.

 

Best regards,

Jethro

I just booted with Knoppix and retreived this information:

 

fstab:

/dev/sda5 / ext3 defaults 1 1
/dev/sda7 /home ext3 defaults 1 2
/dev/hdc /mnt/cdrom auto umask=0,users,iocharset=utf8,noauto,ro,exec 0 0
/dev/sda1 /mnt/win_c ntfs umask=0,nls=utf8,ro 0 0
none /proc proc defaults 0 0
/dev/sda6 swap swap defaults 0 0

 

lilo.conf:

The exact error I get when trying to boot into the installed Mandriva is:

Can't find ext3 filesystem on sda5

 

I hope this information helps.

I would try booting a Linux CD in rescue mode, and then from the command prompt do this:

 

mkdir /mnt/root
mount /dev/sda5 /mnt/root

 

and see what happens. Check in /mnt/root to see if you can see your filesystem, namely directories and files. If you can, I would then suggest typing:

 

mount

 

and see what file system it says against /dev/sda5. Either, your system is not ext3, or, it's trashed this partition.

I fixed it!

 

This is what I did:

- go into the rescue mode of the Mandriva 2007 install DVD.

- edit fstab via the console, this is what I changed: sda5 -> sda6, sda6->sda7 for all entries.

- choose the option "mount all harddrives".

- choose the option "re-install boot loader".

 

After these steps it al worked again.
