rebuild-tree working for more then 3 days- what to do?

[Shoshannah Forbes]

Hi all. Newbie here :-)
Here is my problem:
I have a Linux gentoo box with a 60GB HD using ReiserFS 3.6. Last 
Sunday, I attempted to do an emerge sync (which is HD intensive), and 
my system froze. After the 2nd time my system froze doing an emerge 
sync, I booted without X and attempted again. This time, just before 
the system froze, I got a panic error about trouble writing to the HD 
(I didn't write it down, so I don't have the exact error message).

So I booted from a DSL CD which I had, and ran reiserfsck, whic 
complained about a few problems. So I ran reiserfsck --fix-fixable, 
which told me that there are problems that it will need to run 
--rebuild-tree in order to fix.

I googled a bit, and as DSL has an old version of the reiserFS tools, I 
went ahead, and using another machine downloaded the latest version of 
knoppix, booted from it, and ran reiserfsck --rebuild-tree. I switched 
to another desktop, but when I attempted to switch back to the original 
one to see the progress, X didn't let me, so I left the reiserfsck 
running, thinking that I would return to it when it will finish.
After 3 days, the HD stopped making noise, but the HD light (and the 
cdrom light, where knoppix is running from) are still on. The Machine 
does answer pings, but still doesn't let me switch to the other 
desktop, and CTRL+ALT+Fx doesn't switch out of X into a virtual 
terminal.

So, I am wondering- what to do now? How to minimize (and hopefully fix) 
any damage to that disk?

Thanks!

correction:
CTRL+ALTF2 did respond- after a few minutes. It is scrolling messages 
by way to fast to read.

Hmm, 3 days for 60gb? I believe something is wrong there.

I would move the problem hard disk to mashine which has (or can
download) latest reiserfsck
(http://thebsh.namesys.com/pub/reiserfsprogs/reiserfsprogs-3.6.19.tar.gz),
make sure that it performs I/O of that disk decently (hdparm -t
/dev/problem-disk) and run reiserfsck --rebuild-tree for broken
filesystem there.

Thanks for the fast reply.
The only other machine I have here is a Mac running OSX. Would it even  
be possible to do this from a Mac?
If not, can anything be done from a LiveCD?

When you boot off liveCD - do you have a network and place where
reiserfsprogs can be put and compiled besides that 60gb device with
broken reiserfs?
Then boot liveCD, download reiserfsprogs and fsck.

  There are liveCD's with reiser4 and reiser4progs. For example: http://lxnay.dnsalias.org/livecd-iso/index.php

As the system there is Gentoo, and this LiveCD is gentoo, this looks 
like my best bet.
Well, heading for the download now. See you in a few days (hopefully 
after rebuild-tree is finished)...

Spam is about reiser4!! progs. Whereas you need reiserfsprogs.

reiserfsck --rebuild-tree 's speed depends of file set substantially.
The worst case - a lots (millons) of small files.
But even in that case on average today hardware it should not take more
than 4-5 hours for 60gb filesystem.
Please inform us how does it progress. Pass 0 is the longest usually.

It ran, fixed some errors, and now I have my system back (plus a bunch of portage files in lost+found). Yippy!
Now I should go a buy that DVD-R I was thinking of getting, and make sure I have proper backups :-)

Thanks all!

Not sure about this.. but I have observed that some systems trash resierfs3
pretty badly, while others do not.  The problem seems a bit worse with LVM.
For example a Compaq n610c laptop will trash reiserfs3 on hard shutdown or crash
about 1 out of every 3 times (with entire directory trees going to lost+found
even though no writes involved the files there).  Likewise for my dual
AMD using the Tyan S2468UGN mb.  But my laptop, Toshiba 3000-s504 is fine.
And my dual Opteron (Sun w2100z) is fine.  These can be crashed, powered off
without everything going into lost+found.  I suspect something is up.. and
it may be chipset related (??).

Can't explain it.... just what I've observed.

FWIW, my machine is a cheap AMD duron with a SiS 740 chipset.

Not locally (that machine has only one HD), but I can mount a share on 
the Mac via the network.
I guess I'll try that.

When you boot of liveCD root filesystem gets created in memory. You
should able to put reiserfsck there

Alternatively, try the following. Go to slackware.com Grab a reiser3
enabled boot image and make a bootdisk.
If memory serves me right, this is the one you want 
ftp://ftp.mirror.ac.uk/sites/ftp.slackware.com/slackware-10.0/kernels/ba
reacpi.i

Then, go into
ftp://ftp.mirror.ac.uk/sites/ftp.slackware.com/slackware-10.0/rootdisks/
and grab rescue.dsk and make a rootdisk. You could go two ways about it
from now on
If there is space on the rootdisk, mount it and copy the reiserfsprogs
binaries into it.
If not, use a third disk to hold the binaries.

Boot off the bootdisk, slam the rescue rootdisk in when requested, and
best of luck :D

Yiannis.
