What does this mean?

[Basil Chupin]

I am running SuSE 8 and the HD is being accessed every 5 seconds by 
"something". I thought I would just do a quick check of the reiserfs but 
on executing "reiserfsck --check --logfile check.log  /dev/hda7" this 
produces the error message "/dev/hda7 is mounted w/ write permissions, 
can not check it." I cannot find this message documented so am wondering 
what it means, and what do I need to do in order to be able to check the 
integrity of the reiserfs on my sytem. Can anyone please help?

Cheers.

You can only check integrity on read-only mounted fs.
You can only fix stuff on completely unmounted fs.

I really do not know what is causing this every-5-seconds access. This 
is why I am trying to check the integrity of the fs as part of my 
exercise of finding the reason for the access.

Someone else responded to me earlier with the statement to execute 
following: "mount -o remount,rw  /dev/hda7" which I thought had the "rw" 
wrong; but by changing the "rw" to "ro" I then got the error message, 
"mount: / busy".

All this is perplexing me, firstly because I am not tryng to change 
anything- all I am trying to do is to do what the blurb about reiserfs 
says which is "do this to CHECK the fs"; and secondly, how could one 
ever effect any corrections to the fs if it cannot be mounted!?

All too much for a country lad to fathom.

To *check* the filesystem at all, mount it in read-only mode. Oftentimes you 
need to stop most services to do that, say go to singleuser mode via
# telinit 1

To *fix* the filesystem, it *must* be unmounted, period. Typically, you will 
want to make a minimal "rescue" root partition on your hard drive, reboot 
with this partition given to kernel as the root (root=/dev/hdxxxx), and then 
run reiserfsck on your main root partition.

This is normal and expected for your kernel version, AFAIK. Integrity of the 
fs has nothing to do with it (alas, do maintain the integrity, please ;-)

Integrity have nothing to do with that with 99.9% probability.

Sure. You can do this in single user mode, though.

This is a balanced tree filesystem, so metadata flies all over the place on
disk, so to ensure metadata stability, for check you need your volume to
at least to be mounted read only.

I take the opporunity in this message to thank all who have responded to
my queries as doing so will save me some typing :-).

Re what you just said about this being "normal and expected for your
kernel version, AFAIK" I need to say that this is the reason why I am
querying this accessing because I don't believe that it is - and i'll
give my reason in a minute. Firstly, I want to say that  following advice
from at least a couple of people I was able to work out (I am new to
Linux so don't really know what I am doing) how to check the reiser fs
on my system. It is fine, of course. I needed to have it checked out,
though, because I had to eliminate this as a variable in my attempt to
find out why my HD(s) is/are being accessed by something every 5 seconds.

Please let me give a brief resume of why I am trying to find out why my 
HD is being accessed every 5 seconds (actually it is also occurring on 
another computer at home and a friend's machine -- and all are running 
SuSE 8.0).

  I first asked this Q isn another forum and received the general reply 
that it all had to do with the reiser fs -- which I didn't really 
believe. Why? because I didn't recall having this "problem" when I was 
running SuSE v7.2 with reiser fs. But just to be sure I started doing 
some testing.

I have another HD which I use for testing purposes and on this one I 
installed SuSE v7.2 undere reiserfs. There was no 5 second accessing on 
the HD.

I then installed SuSE 8 with ext3 (because someone said that the 5 
seconds-thingie only happened under reiser) - and I still got the 5 secs 
access. So, it wasn't confined to reiserfs.

Following the comment in this forum that I can only run reiserfsck if 
the fs is not mounted or if I am in single-user mode, I went into 
single-user mode and guess what? As soon as one goes into single-user 
mode the 5 second accessing stops! Interesting, no?

And just to add more interest to the whole epic, I decided to do another 
  install of SuSE 8 under reiserfs on my test drive. I did an identical 
install as I made on my other 2 computers and --- you guessed it: this 
time there is NO 5 second accessing of the HD (on the test system)!

So, that's the story, and I am still wondering why 3 systems runing SuSE 
8 under reiserfs are having the HDs accessed every 5 seconds yet this 
does not occur on a (near identical) test system installed recently.

Cheers.

Thank you for the explanation.  I am on a learning curve in Linux so the

Note that ext3 *also* has a 'kjournald' that ticks every 5 seconds.

I'm willing to bet that the system that wasn't seeing the ticking had all
the filesystems mounted as ext2, which doesn't have a journal.

Had you bet you would have lost! :-). All systems are operating under 
reiserfs.

You mentioning kjournald brought to min a conversation I had with a 
friend of mine who tends to have a similar approach to me when starting 
to run a new system (Linux [SuSE] in this case) and who also uses a 
second HD to test new installations before putting them onto the 'main' 
system.

We compared the outputs from the 'ps aux' command and what I found is 
that I am not running the kjournald process on any of my (3) 'systems' 
 while he is (on his 2 'systems') even though our setups are almost 
identical (with regards to running SuSE v8 ). I thought kjournald was 
part and parcel of reiserfs but then why isn't it running on my 
'systems'? Just another mystery.

Anyway, I think I have found the reason why I (and my friend and some 
other(s)) am having the HD accessed every 5 seconds, and after I have 
re-checked my finding I'll post the reason. It may not have anything 
directly to do with reiserfs but it may be  that another application may 
be causing reiserfs to misbehave (in this 5-second syndrome) or, of 
course, it has a bug in it causing the kernel to do the 'wrong thing' 
(the application does a patch to the kernel).

Cheers.

ext2 filesystems don't have a kernel thread.
ext3 have one kjournald thread per file system.
resierfs have one kreiserfsd thread per file system.

You don't have any because you're all reiserfs.  His two systems obviously
have at least 1 ext3 file system (/boot or / perhaps?)

Ah, now this is something I believe he does not have. Like me he 
installs everything under the one file system. Howeve, I will check with 
him just in case he somehow misconfigured his system by accident (or 
design).

I apologise for the delay in following-up on this topic but I have been 
occupied on other things (including upgrading my system).

What I found is that, at least in my case (and my friend's), the 
5-second accessing of the HD is caused by Win4Lin. As soon as I/we boot 
into SuSE without the win4lin kernel the accessing stops and the system 
is quiet as a mouse. I am in touch with NeTraverse (Win4Lin) and they 
are investigating this matter.

In a different forum someone mentioned that when he un-installed 
seti-at-home the 5-second accessing on his system stopped - I mention 
this in case this is of interest to anyone.

I did some extensive (for me, that is :-)) testing and found that the 
5-second accessing occurs when either reiser or ext3 file systems are 
installed but the access time "drops" to once every 35 seconds if ext2 
fs is used. Interesting (?).

Cheers.

Its a message we really need to drop. Very old kernel loaders used to

No services there, this packet is certainly invalid. Some OS's respond to
them with tcp rst, some just drop them.

Yes they are TCP flags, CWR & ECE are ECN extensions to the TCP header.
Read RFC 3168.

Note, some routers outthere are not ECN aware and violate RFC 3168 by
dropping these packets. This causes interoperability problems, which
should be resolved by vendors.

 In my raidtab file, sdc = 7 and sdd = 8. Is there some type of error here?
The linear seems to be working properly, but since I'm such a newbie, I
can't tell for sure. I wish there was a better way to check on the raid
status.

Thanks,
Michael

                           ^^^^^            ^^^^^

Well, you're in luck, because these numbers are the major and minors for
sdc and sdd:

$ ls -l /dev/sdd
brw-rw----    1 root     disk       8,  48 May  5  1998 /dev/sdd
$ ls -l /dev/sdc
brw-rw----    1 root     disk       8,  32 May  5  1998 /dev/sdc

(hex 20 and 30 => decimal 32 and 48)

I'm not sure why md sometimes puts the major:minor instead of the device
name. Perhaps has something to do with the driver for your sdc and sdd?
I'm guessing here...

At http://urchin.earth.li/cgi-bin/ecn.pl?output=ip is a list with routers with
are known to violate ECN. There is even a perl-script around wich uses the
--remove-ecn feature of the ECN target to create rules based on that list of
IP-addresses. Quite nice, since it sorts out the problem locally - but not in
a global sense. Call it self-defense.

Hi there everybody,

I have one question :

	Each time I look into my firewall logs, I see many dropped packets 
that match this pattern :

	Protocol 		: TCP
	Source port	: 80
	Dest port		: 1024-65535
	Flags		: ACK FIN

Where are those packets comming from ?

Thanks for reading and Thanks for each answer I get ...

That would be IE clients browsing the web. IE is the only browser I've
found that does this.

So I can add a rule to drop thos packets without having any problems ?
(That could clear the logs a bit ;-))

.../lm_sensors-2.6.4/prog/detect/sensors-detect

gives this result:
...
Probing for `Winbond W83697HF'
   Trying address 0x0290... Success!
     (confidence 8, driver `Unwritten (W83697HF)')
...

Does it mean that "there is no driver for the chip "Winbond w83697hf"??
But i read that the driver w83781d should fit.

If I do:

modprobe w83781d

I got "No sensors found!"

Any help appreciated!!

What does this mean?

[Mark D. Studebaker]

you must not really be running sensors-detect from our 2.6.4 release.
We added support for the 697HF in 2.6.3.

what does this mean?

[Steve Iribarne (GMail)]

My code is hitting in sched.c ->

=09if (unlikely(in_interrupt())) {
=09=09printk("Scheduling in interrupt\n");
=09=09BUG();
=09}
It is hitting this printk.  So is this telling me I'm calling schedule
from within an interrupt?  How can this be?  Has anyone else seen
something like this and can anyone give me a hint as to what to look
for.

Thanks.

Check to make sure that in your interrupt handler you are not calling
something that can sleep.  E.g. sleep(), usleep(), kmalloc(), vmalloc(),
etc.

Also watch out for semaphore operations such as down() and
down_interruptible().  They can sleep too.

Thanks.  That's what I think it is, but I didn't write this code so
I'm trying to track down
who is calling down at interrupt time.
