SubjectRe: 2.4.18-rc3aa3: dma_intr: status=0x51 errors
From

Thanks for the answers. Also, it is 2.4.19-rc3aa3 not whats in the
subject.

The man page for badblocks encourages me to use e2fsck -c to run
badblocks and to not run it directly. That, in addition to the hint
from Alan that I was testing the incorrect range with badblocks lead to
wanting to run e2fsck -c -c /dev/vg01/biglv. That lead to:

kernel: lvm -- lvm_blk_ioctl: unknown command 0x24b
last message repeated 1443 times
message repeated 1422 times

Then I thought, e2fsck works on filesystems and badblocks works on
partitions so maybe this is not a good idea after all? What are the
correct numbers to feed to badblocks to get it to test that portion of
the disk?

Then some of these popped up a few minutes later:

smartd: Device: /dev/hda, S.M.A.R.T. Attribute: 231 Changed 11
smartd: Device: /dev/hde, S.M.A.R.T. Attribute: 231 Changed 8
smartd: Device: /dev/hdg, S.M.A.R.T. Attribute: 7 Changed -53

This clued me into the fact I had previously enabled this SMART on this
box. I don't know much about SMART and I can't seem to find much about
which of the below errors are truly fatal and whats normal. I did a
short self test too.

I see the raw read error rate is 0 but it failed the self test in the
read element!?

Is 11964485 a large number for Hardware ECC Recovered?

The drive is totally pooched I guess? Any light you could shed on which
of the below numbers are the tell-tale signs that the drive is dying
would be appreciated.
