Hi,
I'm currently experiencing freezes with drbd each time I run PostMark,
an io benchmark from NetApp. It was working all right on a 2.6.12
kernel and version 0.7.11 but I'm currently switching to 2.6.15 with
version 0.7.15.
Freezes occur on the primary node while creating thousands of files.
Secondary node is not impacted.
I've tried latest svn commit (2064) and kernel 2.6.15.4. Same problem.
My kernel is configured with high memory support (64GB), PREEMPT, ...
The filesystem drbd is on is xfs. Hardware is a pair of DL380 from HP.
Network for drbd is a private Gb link on bcm5700 interfaces.
You can find the postmark benchmark here :
http://www.eecs.harvard.edu/~syrah/filesystems/code/postmark-1_13.c
(The one we really use is 1_5 but I cannot find it anymore on the
Netapp website, I can post it if needed)
It's configured this way :
set number 200000
set transactions 1000000
set size 500 10240
set read 4096
set write 4096
Here is my drbd.conf:
global {
minor-count 5;
dialog-refresh 5;
}
resource vol0 {
protocol C;
incon-degr-cmd "echo '!DRBD! pri on incon-degr' | wall ; sleep
60 ; halt -f";
startup {
wfc-timeout 60;
degr-wfc-timeout 120;
}
disk {
on-io-error detach;
}
net {
on-disconnect reconnect;
}
syncer {
rate 100M;
group 1;
al-extents 257;
}
on bwinf5401 {
device /dev/drbd0;
disk /dev/cciss/c0d0p10;
meta-disk /dev/cciss/c0d0p7[0];
address 10.0.0.1:7789;
}
on bwinf5402 {
device /dev/drbd0;
disk /dev/cciss/c0d0p10;
meta-disk /dev/cciss/c0d0p7[0];
address 10.0.0.2:7789;
}
}
Here are my /proc/partitions :
major minor #blocks name
104 0 142253280 cciss/c0d0
104 1 1048559 cciss/c0d0p1
104 2 1048560 cciss/c0d0p2
104 3 2097120 cciss/c0d0p3
104 4 1 cciss/c0d0p4
104 5 1048559 cciss/c0d0p5
104 6 1048559 cciss/c0d0p6
104 7 1048544 cciss/c0d0p7
104 8 2003264 cciss/c0d0p8
104 9 58596944 cciss/c0d0p9
104 10 74313104 cciss/c0d0p10
147 0 74313104 drbd0
I've attached my .config.
Hope you will find this useful. I can test patched versions and would
be glad to do so.
Thanks in advance,
LD

please try with latest svn
svn co http://svn.drbd.org/drbd/branches/drbd-0.7
I just checked in a one line change where we used GFP_KERNEL where we
should have used GFP_NOIO...
cheers,

Thanks a lot for the answer, I wondered if my bug report wasn't too
stupid to reach the mass audiences ;).
I've just tried today with kernel 2.6.16 (sorry for that kernel are
evolving fast here ;), if needed I can test with the 2.6.15.4 we had)
and Monday's latest svn.
Postmark 200k files creation completed successfully but the
transaction part crashed again the host. Could there be the same bug
elsewhere in the code ?
Cheers,
LD

No.
I think.
I reviewed all places with GFP_somthing,
and I did not see any other memory allocation
without NOIO in the io path. But I may have overlooked something.
what do you mean by "crashed the host"?
any output anywhere?
any reaction to ping, keyboard, numlock-led-toggle, sysrq keys?
nmi-watchdog enabled? does it trigger?
are you comfortable to recompile the kernel with the kernel debugger enabled,
and go into the kernel debugger when it "crashes" again, and see what it
thinks it does, where it thinks it is stuck?

Hi,
Quick answer, I'll try to get some more time on that later today.
> what do you mean by "crashed the host"?
The host is inside a server room, I don't have any quick access to it
yet, I'll configure the iLO remote management stuff later today. So
far the crash is :
- ssh console frozen
- no more ssh access (timeout)
- ping still ok
- "Unknown" status for the host seen on the other node
- automated reboot by HP's bios after 15 min.
> any output anywhere?
nothing into the syslog files as usual when the kernel has hard time ;)
but here is the output of drdb before the crash (maybe to validate my conf) :

no problem to recompile a kernel with the debugger
this will be my first time using it but I'm looking forward to learn...

I do not think that this has anything to do with DRBD. In the call
graph is no single trace of DRBD, nor is it one of DRBD's kernel
threads.
I think that this report should go to the kernel-mailing list.

Hi Laurent,
Could you send me please that 1_5 release of that benchmark ?
Thanks! - We will try to reproduce this here.

Hi,

Here it is. On my side, unfortunately, the cluster is going into
production soon though without drbd. I won't be able to make any
further test within the next few days, in fact, until I set up again a
pair of test servers.
Symptoms are fully reproductible. It happens each time the benchmark is ran.
Here is a sample session which we always use :
PostMark v1.5 : 3/27/01
pm>set number 200000
pm>set transactions 1000000
pm>set size 500 10240
pm>set read 4096
pm>set write 4096
pm>show
Current configuration is:
The base number of files is 200000
Transactions: 1000000
Files range between 500 bytes and 10.00 kilobytes in size
Working directory: /DRBD
Block sizes are: read=4.00 kilobytes, write=4.00 kilobytes
Biases are: read/append=5, create/delete=5
Using Unix buffered file I/O
Random number generator seed is 42
Report format is verbose.
pm>run
Without the settings above, postmark akways pass but it's a very short test.
Cheers,
LD

Versions:
1.00 - Original release - 8/17/97
1.01 - Fixed endless loop on EOF,
Divide by zero when file_size_high=file_size_low - 10/29/97
(Thanks to Chuck Murnane)
1.1 - Added new commands to distribute work across multiple directories
and/or file systems and multiple work subdirectories.
Changed set location command (+,-) to allow file systems & weights
Added set subdirectories command and code to distribute work across
multiple subdirectories
Added file redirect to show and run commands
Improved help system - 4/8/98
1.11 - Fixed unfortunate problem where read_file opens in append mode thus
avoiding actual reads. (Thanks to Kent Peacock)
1.12 - Changed bytes read and written to float. Hopefully this will avoid
overflow when very large file sizes are used.
1.13 - Added terse report option allowing results to be easily included in
other things. (Thanks to Walter Wong)
Also tweaked help code to allow partial matches
1.14 - Automatically stop run if work files are depleted
1.5 - It was pointed out by many (most recently Michael Flaster) that the
pseudo-random number generator was more pseudo than random. After
a review of the literature and extensive benchmarking, I've replaced
the previous PRNG with the Mersenne Twister. While an excellent PRNG,
it retains much of the performance of the previous implementation.
URL: http://www.math.keio.ac.jp/~matumoto/emt.html
Also changed MB definition to 1024KB, tweaked show command

The "Artistic License"
Preamble
The intent of this document is to state the conditions under which a
Package may be copied, such that the Copyright Holder maintains some
semblance of artistic control over the development of the package,
while giving the users of the package the right to use and distribute
the Package in a more-or-less customary fashion, plus the right to make
reasonable modifications.
Definitions:
"Package" refers to the collection of files distributed by the
Copyright Holder, and derivatives of that collection of files
created through textual modification.
"Standard Version" refers to such a Package if it has not been
modified, or has been modified in accordance with the wishes
of the Copyright Holder as specified below.
"Copyright Holder" is whoever is named in the copyright or
copyrights for the package.
"You" is you, if you're thinking about copying or distributing
this Package.
"Reasonable copying fee" is whatever you can justify on the
basis of media cost, duplication charges, time of people involved,
and so on. (You will not be required to justify it to the
Copyright Holder, but only to the computing community at large
as a market that must bear the fee.)
"Freely Available" means that no fee is charged for the item
itself, though there may be fees involved in handling the item.
It also means that recipients of the item may redistribute it
under the same conditions they received it.
1. You may make and give away verbatim copies of the source form of the
Standard Version of this Package without restriction, provided that you
duplicate all of the original copyright notices and associated disclaimers.
2. You may apply bug fixes, portability fixes and other modifications
derived from the Public Domain or from the Copyright Holder. A Package
modified in such a way shall still be considered the Standard Version.
3. You may otherwise modify your copy of this Package in any way, provided
that you insert a prominent notice in each changed file stating how and
when you changed that file, and provided that you do at least ONE of the
following:
a) place your modifications in the Public Domain or otherwise make them
Freely Available, such as by posting said modifications to Usenet or
an equivalent medium, or placing the modifications on a major archive
site such as uunet.uu.net, or by allowing the Copyright Holder to include
your modifications in the Standard Version of the Package.
b) use the modified Package only within your corporation or organization.
c) rename any non-standard executables so the names do not conflict
with standard executables, which must also be provided, and provide
a separate manual page for each non-standard executable that clearly
documents how it differs from the Standard Version.
d) make other distribution arrangements with the Copyright Holder.
4. You may distribute the programs of this Package in object code or
executable form, provided that you do at least ONE of the following:
a) distribute a Standard Version of the executables and library files,
together with instructions (in the manual page or equivalent) on where
to get the Standard Version.
b) accompany the distribution with the machine-readable source of
the Package with your modifications.
c) give non-standard executables non-standard names, and clearly
document the differences in manual pages (or equivalent), together
with instructions on where to get the Standard Version.
d) make other distribution arrangements with the Copyright Holder.
5. You may charge a reasonable copying fee for any distribution of this
Package. You may charge any fee you choose for support of this
Package. You may not charge a fee for this Package itself. However,
you may distribute this Package in aggregate with other (possibly
commercial) programs as part of a larger (possibly commercial) software
distribution provided that you do not advertise this Package as a
product of your own. You may embed this Package's interpreter within
an executable of yours (by linking); this shall be construed as a mere
form of aggregation, provided that the complete Standard Version of the
interpreter is so embedded.
6. The scripts and library files supplied as input to or produced as
output from the programs of this Package do not automatically fall
under the copyright of this Package, but belong to whomever generated
them, and may be sold commercially, and may be aggregated with this
Package. If such scripts or library files are aggregated with this
Package via the so-called "undump" or "unexec" methods of producing a
binary executable image, then distribution of such an image shall
neither be construed as a distribution of this Package nor shall it
fall under the restrictions of Paragraphs 3 and 4, provided that you do
not represent such an executable image as a Standard Version of this
Package.
7. C subroutines (or comparably compiled subroutines in other
languages) supplied by you and linked into this Package in order to
emulate subroutines and variables of the language defined by this
Package shall not be considered part of this Package, but are the
equivalent of input as in Paragraph 6, provided these subroutines do
not change the language in any way that would cause it to fail the
regression tests for the language.
8. Aggregation of this Package with a commercial distribution is always
permitted provided that the use of this Package is embedded; that is,
when no overt attempt is made to make this Package's interfaces visible
to the end user of the commercial distribution. Such use shall not be
construed as a distribution of this Package.
9. The name of the Copyright Holder may not be used to endorse or promote
products derived from this software without specific prior written permission.
10. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
