RE: Unknown Issue.

[hard__ware]

Im having the same issue on a 2.6.9 kernel ...

Dell PowerEdge 2650 /w Adaptec AACRaid 
In hardware Raid 0 (stripe array)

am finding that some of the earlier 2.6  kernels were
a bit more stable ... 

only seem to get input/output & bus errors when
high load is present on the system ... e.g. Backup ... 


Thanx ...

For main system: To make a long story short, I was attempting to hook up
a cd burner and dvd reader to SATA via SATA<->PATA adapters and enable
SATA in the kernel for the Intel ICH5 chipset and I was trying different
drivers/options in an attempt to get them to work.  However, please note
during the entire time, the disk that suffered FS corruption was always
hooked to a Ultra ATA/133 Promise Controller.  I believe I had a kernel
panic once and at another time during either loading SATA drivers or IDE
drivers I had a lockup somewhere along the lines and I rebooted
improperly.

For Dell GX1 system: No, all I did was upgrade the kernel [2.6.9 ->
2.6.10-rc2] and reboot, no power outages or crashes at all.  After about
an hour or so, I began to experience these problems.

Ok, so XVM has found something wrong at this point.  Any chance the box 
had a power failure?  Write caches on ide drives can wreak havoc with 
journaling filesystems...  i.e. what happened between "the filesystem 
was working" and "i remounted the filesystem and got this"

I moved to freebsd as i require the box to actually work, which it
seems to be doing at the moment, even after a bit-o-nailing, but that
still doesn't solve the problem.

RE: Unknown Issue.

[Piszcz, Justin Michael]

So your problem was only temporary?

Or?

After I began having the problem, I was trying to edit some files and
then I got the same errors as you, ie: /usr/bin/vi Input/Ouput error,
and then I tried to run or edit different programs and files and nothing
was working.  

Were you also forced to re-install, or does this only happen sometimes?

I've not tried to reproduce it on a non-gentoo kernel as the original
one that i had the problem was a vanilla kernel ;) ( as i know your
fondness of gentoo's patch-o-lotic )

I've been abusing the box the entire day with FreeBSD, the same mysql
config and version of the mysqld as well as the same operations ( and
some more ... serious ones ( e.g. forkbomb, iozone, etc. ) and no
problem's.

There were no messages in the log, and nothing in kmesg. Anything else
i could try ? Also, as far as i know i was running kernel 2.6.10_rc3
and i'd reinstalled the box twice with new XFS filesystems both times.

Ok, well i couldn't pinpoint it at FS and looked like hardware to me,
i suppose i could redo the box with 2.6.10 and XFS again to see if i
can redo the problem, although i'm partially leaning towards hardware,
but that's the easiest thing to blame :)

I figure i'm going to try out another FS, maby reiser, that should
either do the same, or not, if not, then we know where to start ?

Ah, good question, yes I used xfs_repair, at this point I knew I had to
restore from backup and answered "y" to all questions.  I am not sure
but I do not recall the log being dirty.

In the logs on my main machine, it showed the following when it
attempted to mount the two filesystems (root and boot, /dev/hde4 and
/dev/hde1 respectively).

As far as bad disk/memory, I have tested both systems with memtest86 and
the result was 0 errors, as far as the disks go, I have not experienced
any problems with either of them until I moved to 2.6.9/2.6.10-rc{1,2}.

RE: Unknown Issue.

Patrick,

I had the same problem on two machines with XFS.  Both slackware-current
machines.  The kernel on the Dell GX1 was built with GCC-3.4.2 and on my
main box was GCC-3.4.3.

There seems to be a bug in XFS with some configurations of 2.6.9 and
2.6.10-rc series.

After re-installing Slackware-10.0 and upgrading to -current, I have
installed 2.6.10-rc3 and so far, I have not been able to reproduce the
problem.

Some questions for you:

1] What kernel are you running?
2] What did you last change before you started getting these errors?

As far as severity goes, I ran XFS' fsck from a KNOPPIX CD and as a
result, I had about 500-600mb of files in my /lost+found directory when
it was finished.  Files were missing from all parts of the file system.
I had to restore from backup.  I would say stick with your previous
2.6.9 configuration (if you were running it) or go back to 2.6.8.1, some
2.6.9 configurations and 2.6.10-rc1 and/or 2.6.10-rc2 definitely cause
file corruption with XFS.  So far, however, I have not been able to
reproduce the error with 2.6.10-rc3.

Justin.

Hi, 

I've got a computer running gentoo, on a clean install where i've got
an odd problem :

after a while, the computer refuses to spawn processes anymore : 

-/bin/bash: /bin/ps: Input/output error
-/bin/bash: /usr/bin/w: Input/output error
-/bin/bash: /bin/df: Input/output error
-/bin/bash: /bin/mount: Input/output error

It happen's randomly, i've tried everything from changing the computer
from running software raid ( scsi ) to running a hardware solution and
reinstalling, I've run the memory through memtest as well as i've
remounted the drives and i've tested the ram to make sure it was
properly mounted.

The only thing running on this box is mysql, which runs perfectly at
7500 q/s ( running super smack ) now, i'm not sure if this is a linux
kernel thing, or a gentoo thing, or a hardware thing.

I've checked and i'm not running out of file descriptors ( by looking
in /proc/sys/fs/file-nr ) and i've increased the ammount in (
/proc/sys/fs/file-max ( if i member correctly ) ) by adding a 0 after
the end of the value thus increasing it alot.

It's running XFS on the root partition with a single partition, dual
xeon 2.66 with hyperthreading enabled, dual intel gbe and a adaptec
2120S AACraid card. Dual 36gb 10krpm scsi drives in raid1.

Does anyone have any ideas on what i can do, what i can test, if it's
hardware ? software ?

guys ?
