[gentoo-user] reiserfs troubles

I am currently trying to backup everything on my laptop in order to
repartition it. My root partition, /dev/hda6 is a reiserfs file system. /opt
is currently on the root partition.

# cd /opt/whatever
# chmod +r helpindex.xml
chmod: cannot access `helpindex.xml': Permission denied
# dmesg | tail -n 5
hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hda: dma_intr: error=0x40 { UncorrectableError }, LBAsect=19603129, high=1, low=2825913, sector=19603129
ide: failed opcode was: unknown
end_request: I/O error, dev hda, sector 19603129
ReiserFS: hda6: warning: vs-13070: reiserfs_read_locked_inode: i/o failure occurred trying to find stat data of [5806433 5806438 0x0 SD]

This file isn't really important to me but I seem to have a lot of
them in /opt. I am quite curious about what can be done with this..

Thanks in advance.

If you have smart enabled (and you should have) and smartmontools installed 
(you should have done that too), smart can tell you, if it is a hardware 
problem (which is pretty probably the cause of the problem).

Back up everything...

Thank you very much for the pointer. I had never heard of this before but it 
is definitely going on it the future.. It confirms that the disc has 39 bad 
blocks so now I am reading the faq to figure out how to deal with this. :)

> Back up everything...

As stated in the original post I am trying to.

But when I try to copy everything to an external harddrive after some time the 
external harddrive is disconnected. I am not sure if this is a separate issue 
or if it happens as a result of too many errors on my system disk.

Anyway I have backed up everything that cannot be replaced so first I will 
deal with the bad blocks and then if the problem remains I will probably tar 
everything up to my server via ssh..

Thanks to you and Boyd for your replies on this too. From Boyd's post I am 
guessing that it works as well as it can work and from yours I am guessing 
that it needs some more configuration than you have done. Not sure though..

as the others said, start digging a grave for this drive.  Had a  
drive doing the same thing on  a production box for a few months,  
phbs waited till it just died to order the replacement.  these kinds  
of errors are warning signs of impending doom.

on the other hand, my drive has 705 bad sectors since I played around with S3 
standby abd using the reset button way too often.

Since then - two month now, the harddrive says, it will die in the next 24 
hours - but it still works fine...

I know, what went wrong, the S3 stuff really confused my box and hitting reset 
while doing harddisk accesses was the final drop. It has not become worse 
since then, which makes it an urgent case for replacement, but not an 
emergency....

I backed up everything really important, and will buy a new one in the next 14 
days.

But this is different from 'suddenly fs errors popped up' which is not true in 
my case. If sudden fs errors appear and bad blocks, the disk is on the 
highway to the harddisk fairy in the heart of Lalaland.

Just to follow up on this one. It did last a couple of weeks before I really 
started digging into this. It has turned out that you and Volker Armin were 
right. I never was able to backup that particular partition 
(containing /, /usr, /tmp, /opt, /var, /etc) since even dd if=/dev/hda6 gave 
up after a while reporting an I/O error. All other partitions, however, are 
backed up properly, and nothing that could not be replaced was on that 
partition.

At present I have tried reiserfsck --badblocks bad.txt  with 
both --fix-fixable and --rebuild-tree. --fix-fixable told me to 
run --rebuild-tree and --rebuild-tree failed leaving the partition 
unmountable. I also tried dd if=/dev/zero of=/dev/hda6 which failed after a 
while. I finally tried formatting the partition with NTFS just to see if 
Windoze handles this better. Formatting it worked fine, scandisk returned no 
errors and I could copy 1,5 GB of data to the partition before it failed with 
a hardware error... In other words it doesn't. ;)

Also during all those attempts the Current_Pending_Sectors reported by 
S.M.A.R.T. has grown from 39 to now 102..

So the result is that I have used another partition for my system since last 
friday and that the drive will be replaced next monday. Since that other 
partition is way smaller than the one I used to use and because it is such a 
short time, I thought I'd take the opportunity to try another distribution 
i.e. Kubuntu Dabber (beta) with KDE 3.5.2. I must say that I am impressed by 
the present state of Kubuntu, but I also really miss the control that Gentoo 
provides so next monday I'll be installing Gentoo on a brand new and more 
partitioned harddrive. :) I also really miss something equivalent to 
eix/diff-eix/eix-sync for Debian based systems.

Hopefully (and probably) an insurance I have will pay for the replacement 
(except I'm going to purchase a bigger drive and will pay the difference).

That's what kmail says to me.
