Subject: Severe reiserfs problems

Hi,

I have severe file system problems on a reiserfs partition.
When I try copy files to another filesystem, the kernel panics at certain
files.

reiserfsck --fix-fixable says that I need to run
reiserfsck --rebuild-tree to fix the errors, but when I do this,
reiserfsck hangs after a few secounds.
Is there a way to rescue at least some of the data on the partition?

Any help is highly appreciated.

TIA,
Robert

I had a behaviour somewhat like this once which turned out to be defunct
memory. Though I can't help you with data recovery I would advise you to
run memtest86.

Can you tell us what the panics were?
What was the kernel version?

What's the reiserfsck version you have?
What do you mean by hangs? Does it eats cpu time or something?

There is not enough info yet to know the answer.

It said "... killing interrupt handler!"
However, the message is not exactly reproduceable.
Meanwhile, when I mount the partition in the rescue system (SuSE Linux
8.1) and access the mountpoint somehow, the machine reboots...

I have tried tried SuSE 8.0 and 81 rescue systems with kernels 2.4.18.and
2.4.19 / reiserfsck 3.x.1b and 3.6.2 with the same result.

It just freezes doesn't react to key presses no more.
All you can do is swith the computer off...

Hm, sounds like you have some hardware problems then.
May be try plugging this hard drive in another system and see what will happen?
