EXT3-fs error on kernel 2.4.18-pre3

EXT3-fs error on kernel 2.4.18-pre3

[Anton Altaparmakov]

Hi,

I just noticed that my file server running 2.4.18-pre3 + IDE patches &
NTFS patches has this error message in the logs:

EXT3-fs error (device md(9,4)): ext3_free_blocks: Freeing blocks not in
datazone - block = 33554432, count = 1

This is the only ext3 error I have seen and the uptime is currently over
74 days. The error actually appeared two weeks ago. The timing coincides
well with when this device (/dev/md4, a MD RAID-1 array) ran out of
space, so it may well be related.

All seems to be working again after I freed up some space. Haven't run
fsck as I would hate to down the server with that nice uptime...

Should I be worried?

I am only mentioning this as I suppose it may be a bug somewhere in
ENOSPC handling, so perhaps someone is interested in this report...

Best regards,

	Anton

This was fixed in newer kernels.

Cheers, Andreas

I thought I'd try to beat Andries to noting this: That's 0x2000000!

No, the out-of-space behaviour was either an ext3_error if we ran out
of inodes, or a minor i_nrblocks accounting error if we ran out of
disk blocks.

The bad pointer here is 0x2000000, and a bit flip like that is more
often an indicator of bad memory than anything else.

Cheers,
 Stephen
