Hello to the List Members!
I was searching the Internet (and this list) for a
while, and found many people with similar symptoms. I
could find no satisfactory solutions to their
problems, though. So, I decided to ask here.
I've got a RedHat 9.0 SMP system (L440GX motherboard,
2x650 Pentium III, 1GB RAM). There are two SCSI disk
drives and two IDE disk drives (connected to a Promise
ATA-100 card).
Linux l440gx 2.4.20-20.9smp #1 SMP Mon Aug 18 11:32:15
EDT 2003 i686 i686 i386 GNU/Linux
The following is the fdisk -l output for the disk
drive in question (MAXTOR 120GB):
Disk /dev/hdg: 122.9 GB, 122942324736 bytes
255 heads, 63 sectors/track, 14946 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id
System
/dev/hdg1 1 14946 120053713+ 83 Linux
Here is my problem. System worked OK for a while
(several months). Recently, I found the file system
re-mounted read-only, and the following messages in
the syslog:
Sep 29 05:04:46 localhost kernel: hdg: dma_intr:
status=0x51 { DriveReady SeekComplete Error }

I booted from a floppy, and ran Maxtor's diagnostic
program (full scan) - no problems detected.
I ran 'badblocks' as well, on /dev/hdg, and it went
OK.
I successfully read the whole drive (
Then I tried to read /dev/hdg1 (the partition) with
dd, and got an error (this example skips most of the
drive, but when I read the whole drive, result is the
same)
[EMAIL PROTECTED] /]# dd bs=10k skip=12000000 of=/dev/null
if=/dev/hdg1
dd: reading `/dev/hdg1': Input/output error
5371+1 records in
5371+1 records out
There were errors in /var/log/messages as well:
Oct 5 21:10:28 localhost kernel: attempt to access
beyond end of device
Oct 5 21:10:28 localhost kernel: 22:01: rw=0,
want=120053716, limit=120053713
Oct 5 21:10:28 localhost kernel: attempt to access
beyond end of device
Oct 5 21:10:28 localhost kernel: 22:01: rw=0,
want=120053716, limit=120053713
This condition is 100% reproduceable. This condition
does not exist on the second IDE drive, nor on any of
SCSI drives.
I have tried the following:
* Create smaller partition (as small as 100MB in the
beginning of the drive) - the same error, dd tried to
read beyond of the partition.
Disk /dev/hdg: 122.9 GB, 122942324736 bytes
255 heads, 63 sectors/track, 14946 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id
System
/dev/hdg1 1 13 104391 83
Linux
Oct 5 21:16:23 localhost kernel: attempt to access
beyond end of device
Oct 5 21:16:23 localhost kernel: 22:01: rw=0,
want=104392, limit=104391
Oct 5 21:16:23 localhost kernel: attempt to access
beyond end of device
Oct 5 21:16:23 localhost kernel: 22:01: rw=0,
want=104392, limit=104391
* Fill the beginning of the drive with zeroes and
re-create partition table - no help either.
I don't know what to think in this situation. I don't
know I have this problem from the very beginning (and
just noticed it when the disk got filled up), or
something broke recently. I don't know if this is a
disk or RedHat problem.
Before I start trying different kernels, I would like
to know your opinion.
Any Help Would Be Greatly Appreciated !!!
Sincerely yours,
Sergey
