ext3 fs corruption with 2.4.17

ext3 fs corruption with 2.4.17

[Christian Hammers]

Hi

Again problems with my filesystems (probably a mainboard/cpu problem). 
It is (^H^H^H was) a quite new ext3 fs that was created with 2.4.17 and the
very latest (stable) e2fsprogs and journalling. The device 8,7 was /var so 
the most used partition for write activity, read activity was mainly under
/usr/local).  

The filesystem was still usable but every write attempt lead to absolutely
nonsense entries so I unmounted and fsck'ed it with quite good success.

Does anybody knows what exactly this means and if it could be helpful to
track down the origin of the problems? Or did anybody else experienced this
messages before?

Are you sure it's not your memory? Run memtest86; I recently had a box
screw up its filesystems because the DIMM went bad.

And that's what I got.

It means your block bitmap is corrupt and it says that metadata blocks
are not in use, when they really are.  That will lead to serious
corruption.

hi

I keep getting the exact same error

EXT3-fs error (device ide2(33,0)): ext3_new_block: Allocating block in system zone - block = 884763
EXT3-fs error (device ide2(33,0)): ext3_new_block: Allocating block in system zone - block = 884764
EXT3-fs error (device ide2(33,0)): ext3_new_block: Allocating block in system zone - block = 884765
EXT3-fs error (device ide2(33,0)): ext3_new_block: Allocating block in system zone - block = 884766
EXT3-fs error (device ide2(33,0)): ext3_new_block: Allocating block in system zone - block = 884767
...

The fs is newly created, and the computer has been working fine all the time.

Anyone know what this is ?

I'm running 2.4.17-tux-ide-rmap11c
