Need some help on reiserfs failure

Need some help on reiserfs failure

[Preston Lord]

Hi List,

On my home pc I am running SuSE 8 Pro.
I have my root partition using reiserfs.
When I woke up this morning the computer was frozen and after rebooting
it tells me there is no root partition defined. I pulled the hdd from
the machine and slaved it into another SuSE 8 pc. If I use Yast2-
Partition Utilities I can see the partitions are defined and the fs is
still being listed as reiserfs on the failed root on the home hdd.

I tried using reiserfsck as follows:

resiserfsck --check /dev/hda4

 reiserfs_open: bread failed reading block 2
 reiserfs_open: bread failed reading block 16
 reiserfs_open: neither new nor old reiserfs format found on /dev/hda4
 reiserfsck: could not open filesystem on "/dev/hda4"

reiserfsck --rebuild-sb --rebuild-tree /dev/hda5

 reiserfs_open: bread failed reading block 16
 reiserfs_open: neither new nor old reiserfs format found on /dev/hda5
 reiserfsck: could not open filesystem on "/dev/hda5"

reiserfsck --fix-fixable /dev/hd5

 reiserfsck: could not open filesystem on "/dev/hd5"


Of course when I try to mount I get the dreaded:
 mount: wrong fs type, bad option, bad superblock on /dev/hda5,
        or too many mounted file systems


Please tell me there is hope?

Thanks in advance.

These two indicate some hardware issue.  reiserfs is unable to read from
the disk at all.  This doesn't mean your disk is gone, but you do need
to look further in your logs for hardware related issues.

Does the kernel detect the drive at all?  If so, please post the
relevant messages.
