bug report (?) with reiserfsck --rebuild-tree.......

[serge rossel]

Hi,

During the system boot (Suse8.1), I get this
boot_log.msg:

Then, in order to solve that, I have tried all the
different commands proposed with reiserfsck.

Look what message I get by using this command.

Thank you for your support
Serge

Vitaly, does the current fsck explain at length that read errors tend to 
be hardware failures, and what to do?

yes, it sais

The problem has occurred looks like a hardware problem.
If you have bad blocks, we advise you to get a new hard
drive, because once you get one bad block that the disk
drive internals cannot hide from your sight, the chances
of getting more are generally said to become much higher
(precise statistics are unknown to us), and this disk drive
is probably not expensive enough for you to risk your time
and data on it. If you don't want to follow that advice,
then if you have just a few bad blocks, try writing to the
bad blocks and see if the drive remaps the bad blocks (that
means it takes a block it has in reserve and allocates it
for use for requests of that block number).  If it cannot
remap the block, this could be quite bad, as it may mean
that so many blocks have gone bad that none remain in 
reserve to allocate.

Serge, if you used the latest reiserfsprogs, you would get 
the message above.
