cannot mount /dev/hdc1

cannot mount /dev/hdc1

[Ingo Rößler]

Hello,

I hope You can help me!

I get at the reboot of  my Suse7.1-Linux-server this message:

mount -t reiserfs  /dev/hdc1 /home : mount: wrong fs type, bad option, bad
superblock on /dev/hdc1, or too many mounted file systems

This is my home-directory - my live!

The harddisk is correct connected. It is a Western Digial 80 GB Harddisk
with only this Partition hdc1.

Well, you might try to rebuild super block. Backup your data first if it 
possible and run:
reiserfsck --rebuild-sb /dev/hdc1

What does it say?

Try also this command:
dd if=/dev/hdc1 of=/tmp/super bs=4096 count=1 skip=16

and send us /tmp/super file please.

Do I understand correctly that you did not use any partitioner just before it happened?
If so, you should run reiserfsck --rebuild-sb to rebuild the super block of your 
fs, then reiserfsck --check and do what it will say. 

But you should update the reiserfsprogs version. 3.6.4 has one critical bug with 
rebuilding huge files, so you should use the latest pre version (3.6.5-pre2) from 
our ftp site (ftp.namesys.com/pub/reiserfsprogs/pre/).

Hi Vitaly and Yury!

> Do I understand correctly that you did not use any partitioner just before

Yes!

But after hard reset, I have this dialog with my server:

elsa:~ # chmod 0777 -R /home/.../letters
chmod: getting attributes of `/home/.../letters/203.gif': Permission denied
elsa:~ # rm /home/.../letters/203.gif
rm: cannot remove `/home/.../letters/203.gif': Permission denied
elsa:~ # chown root -R /home/.../letters
chown: getting attributes of `/home/.../letters/203.gif': Permission denied

Today I am planing a backup and after this a format.
But ...

Ok, tomorrow I do it:

Backup of /dev/hdc1
dd if=/dev/hdc1 of=/sicherung/home.img
(Today I have not a 80 GB backup medium)
Update the reiserfsprogs on version. 3.6.5-pre2

dd if=/dev/hdc1 of=/tmp/super bs=4096 count=1 skip=16
reiserfsck --rebuild-sb /dev/hdc1
reiserfsck --check

I hope, it is good. My hole life is on this disk!

The old Superblock I send to you Yury.

Ciao Ingo

Do you mean that you get the partition mounted somehow? Or it could be mounted
for some time after the reset, and smth happened again and it cannot be mounted 
anymore? Could you tell about it in more details please.

Could you also send what does fdisk -l /dev/hdc say?

Yura is waiting for it.

The hardreset was a few days ago.
The partition could be mounted.

But yesterday night I have the crash. Yet I cannot mount the partition.

Platte /dev/hdc: 80.0 GByte, 80026361856 Byte
255 Köpfe, 63 Sektoren/Spuren, 9729 Zylinder
Einheiten = Zylinder von 16065 * 512 = 8225280 Bytes
Gerät    boot.    Anfang    Ende    Blöcke        ld    Dateisystemtyp
/dev/hdc1            1            9729    78148161    83    Linux

Is it a problem?

Ciao Ingo

No, it is not. Looks as it should be. But your superblock looks wiped out. 
(At least there is no correct magic) And probably smth else also. 
Ok, make a backup and go on with rebuild-sb, etc.

Hi Vitaly and Jury,

the same Partition is repaired!

Many test have no Mistakes produce!

Many Thanks to you!
