Subject: Suspected bug - System slowdown under unexplained excessive disk I/O - 2.4.13

Hi,

I have experienced a condition I believe to be a bug. Below is a bug report
in the format suggested by REPORTING-BUGS:

Summary:

System slowdown under unexplained excessive disk I/O

Full description:

While running X, KDE, having a few windows open, I ran make -j4 on MySQL
source tree. I do this all the time and it usually works just fine - the
system is a little bit unresponsive. However, occasionally the system becomes
completely unresponsive - the disk goes crazy, the machine pings but neither
ssh or telnet work - connection to the port is established, but nothing
further than that. It does respond to magic SysRQ. I was able to get a memory
info dump + stack traces into syslog, included below. The filesystem is
ReiserFS.

Keywords:

vm, ReiserFS, heavy disk I/O,

Some possibly helpful details:

The compile was happening on the ReiserFS partition that was 93% full. As you
can see from /proc/meminfo, I have 0 swap - this is intentional.

I had a similar Problem while running sql-bench on Mysql ( must be mysql :-) ).
First I thought it happened since the Mysql-Tables were on the root-fs and
the Disk did not manage to retrieve normal libs and files for login usw.
But the System (2.4.14-pre8) took about 25 seconds to give a screen after
wakening from apm (triggered by xscreensaver under gnome).
Console-Switching took even longer. Mouse-Movement stopped etc.
Disk-Activity was very high.

I had seen smaller Problems with huge loads on the root-fs earlier. But
never had a Problem with switching consoles or mouse.

I just did a quick retest with sql-bench on my machine and found that
reiserfs seems to be a source for that problem.
I did not reproduce the whole problem, since i stopped
test-create before the system was to unresponsive.

But I started test-create on a partition with
reiserfs. After much files were created the system to very
long for bash command-completion or doing simple thing
free, top etc. this was even after test-create was stopped.
It took about 30 seconds till the system responded normally.

Same test with ext2 on the same partition showed no problems.

Reran the test with reiserfs and the system got unresponsive
again.

Did you use reiserfs ?

Let me guess, IDE disks? Anyway, this is a FAQ. Go http://www.namesys.com, click
on the FAQ, and look at #15.

This issue really can be a problem as the entire machine will freeze up for
a good chunk of time while the disk churns away. Strangely enough, I've
only noticed it on some machines, not all. But it's enough of a problem to
cause me to switch to ext3.

To bad I did not see the Reiserfs-Keyword before asking...
In my case this happened on scsi-disks on a adaptec 2940.
I read the faq-entry, but I do not understand why this should only apply
to IDE. Maybe my old-scsi disks suffer the same problem ?

It could affect certain SCSI disks/controllers just as well. You might want
to ask this question on the reiserfs list to see if they have any
solutions...

It doesn't seem that you have the same problem as Sasha. Reiserfs has
known problem with dealing with large holes, so may be this explains
situation. We'll try to reproduce your results.

Yes, I did. I suspected from the trace resolve this could very well be
ReiserFS issue.
