[gentoo-user] Reiserfs partition corrupted - help!

[Anthony Roy]

Hi All,

Last night I decided to set up a rsync server on my gentoo server box.
I have a partition mounted under /srv, and that was the disk the rsync
module was located on. I then proceeded to rsync the contents of my
main PC over to the server. I tested the scripts a few times first to
ensure that things were working OK, and indeed they were. I then set
it running when I went to bed.

This morning I wake up to find the server had crashed and was
inaccessible. All processes seemed to have shut down. Rebooting the
computer resulted in the reiserfsck being run - and failing!!

I have tried reiserfsck --rebuild-tree /dev/hdc6 and I get a complaint
that the filesystem could not be rebuilt

bread: Cannot read the block (87878789) (Input/Output error)

It also suggests (aside from buying a new disk!) to try overwriting
the blocks if there are only a few of them. How do I go about doing
this?? And does anyone have any other suggestions on how to recover
the filesystem?

Cheers,

This is how I did my search:

I have some use, sometimes anyway.

Hi Dale,

Cheers. I had already googled around, without much success - this
gives me an idea of what to do at least. Looks like I need a partition
of at least the same size as the damaged one to copy the blocks over
to. Unfortunately, I haven't got another *drive* that's as big as that
partition...

Looks like an expensive deal for a single bad block! I'll be getting a
replacement big drive to  replace the damaged one, and a large
external drive to use for backups. Ironic really, as the  server was
supposed to be my backup solution - it has my subversion repository on
it, and an rsync module for backup. Unfortunatly, I'd started to use
it as a webserver etc...

Oh well, first disk corruption in 10 years - got to learn the hard way
sometime...

I have been really lucky.  I have been messing with computers for over
25 years and I don't recall having a hard drive of mine go out.  I have
worked on others that have though.  I guess I replace mine to often.

Lucky indeed - the drive that has gone tits up was only 12 months old...

Yea, I recently threw away some old 14 inch hard drives.  I hooked them
up and they still worked.  I could hear them spin up and heads moving
and all.  I don't have a computer that connects to it, I just got it
some power. 

I do have some really old drives that are less than 1GB and some that
are around 100MBs or so.  They still work fine.  Not sure what to do
with them though.  o_O

I guess they really made them back then.
