Hi,
I''ve been experimenting with Puppet for a few days now, and I really
like it.
But! I''m having real CPU usage problems.
Puppet is still happily eating away 100% CPU for almost an hour at a
time, with no apparent things happening.
(puppetd -tv --trace --debug, but nothing appearing in the console
during this.)
I believe the following resource is to blame:
file { "/some/data/dir":
owner => "$username",
group => "$username",
recurse => "true",
ensure => "directory",
checksum => undef
}
I just want this resource to make sure that all files in the directory
are owned by user and group $username.
/some/data/dir contains 300M in 6000+ files.
This resource executes swiftly, but after the last file has been
chown''d, the puppet hogs the CPU with 100% usage, lasting 40+ minutes.
After that the puppet process finishes normally.
So executing puppet takes about 45 minutes, of which 40 minutes the
CPU usage is 100% and nothing seems to happen.
Some information about my setup:
puppetd en puppetmasterd are 0.25.4
Both running on Xen Dom-U instances
uname -a:
Linux hostname 2.6.18.8 #2 SMP Wed May 27 15:54:07 CEST 2009 x86_64
GNU/Linux
Ubuntu intrepid 8.10
dpkg --list | grep ruby:
ii ruby 4.2 An interpreter of object-oriented scripting
ii ruby1.8 1.8.7.72-1 Interpreter of object-oriented scripting lan
Not really any logging to show, since nothing is logged...
Does anybody have any idea why this happens?
Is puppet just unable to handle large amounts of files and data?
Hoping to be able to use puppet in the near future,
Dieter Van de Walle
PS: I only just discovered this mailinglist, and yesterday I''ve made a
bugpost for this issue:
http://projects.reductivelabs.com/issues/3365
Not really sure if that was appropriate, hope you don''t mind.

It handles large files even worse. The standard advice is "Try putting the files in a package and distributing them using apt." Another common answer is to try combining exec and rsync.

I can''t really believe people would call what I am experiencing "not handling well", so I suppose I''m having another, worse, issue concerning my setup? Also the usual suspect for puppet not handling large file collections well seems to be the checksumming. But with that turned of, what''s keeping puppet busy? Puppet eats up 30 minutes of CPU time, I see two options: - Puppet is doing something necessary for it''s functioning during that time, in which case somebody should know what it is doing.

So, it looks like 30 minutes is being taken up in the Package type and 19 in the File type. The Package type probably won''t eat up much CPU at all as it''s just fetching and installing packages (unless they are some huge packages). You seem to be trying to recursively manage *something* using the File type. What happens is that Puppet creates an actual file object for each file and directory in the recursed path. Then, it takes the graph and applies the changes to each file that has been seen. I''m not certain, but I think that it builds this tree each time it runs to ensure that nothing has changed under the path. This processing has to happen on the client since the server has no previous knowledge of the client''s file structure. That said, for deep directory/many file file statements, just spawn an exec until the internal Puppet logic can be optimized.

Aren''t the time values in seconds? Because I can''t match the "Total: 54.78" line to the "notice: Finished catalog run in 1877.06 seconds" . Also, the strange thing is that the actual changing of owner and group happens pretty fast. I see these messages passing during +- 20s for all files: notice: /File[/some/file]/owner: owner changed ''wronguser'' to ''rightuser'' notice: /File[/some/file]/group: group changed ''wronggroup'' to ''rightgroup'' It''s AFTER this has happened that puppetd stalls for 30+ minutes. So it must be some kind of wrapup action... ?

Also, whatever Puppetd is doing then, it seems to be unnecessary. If I execute puppetd -tv and wait until all files have been chown''d, and then hit CTRL-C and run puppetd again, the second time, puppetd finishes in about a minute. The total process of running puppetd twice takes about 4 minutes . So by manipulating the execution of puppetd using a CTRL-C keystroke I can reach the intended end state in 4 minutes. If I leave puppetd to do it by itself, it takes 30+ minutes of 100% CPU usage...

Hi, Is this directory the only resource you are managing or are there others. If not then try disabling all other resources and see if you still get the same issue?

Yep, you''re right, seconds not minutes. That''s what I get for answering e-mails pre-caffeine. Did you try spitting out a --debug to a file and then post-analyzing that?

Hi,
I must admit I''d really like to like puppet, so I''m a bit
agitated by
this issue, and won''t rest till I know the cause :) .
Sorry for the information overload, hope you don''t mind.
First of all, I''ve followed Martin''s suggestion and simplified
my
config.
This is my configuration in it''s entirety:
nodes.pp:
node ''puptest.domain.com'' {
include onlyone
}
onlyone.pp:
class onlyone {
$pack_list = ["large-package"]
package { $pack_list:
ensure => installed
}
$username = "someuser"
user { "$username":
comment => "Some user",
home => "/home/$username",
managehome => "true",
shell => ''/bin/bash''
}
file { "/data/installed/by/large-package":
owner => "$username",
group => "$username",
recurse => "true",
require => [ User["$username"],
Package["large-package"] ],
ensure => "directory",
checksum => undef
}
}
No effect though, the issue still occurs after all files have been
chown''d.
I''ve also tried attaching gdb to the puppetd process and breaking
during high CPU usage.
If I do a backtrace then, most of the backtrace contains ?? -> can''t
derive.
If I only leave the methods gdb can determine, this is the stacktrace:
st_foreach () from /usr/lib/libruby1.8.so.1.8
st_foreach () from /usr/lib/libruby1.8.so.1.8
st_foreach () from /usr/lib/libruby1.8.so.1.8
st_foreach () from /usr/lib/libruby1.8.so.1.8
st_foreach () from /usr/lib/libruby1.8.so.1.8
st_foreach () from /usr/lib/libruby1.8.so.1.8
st_foreach () from /usr/lib/libruby1.8.so.1.8
ruby_xmalloc () from /usr/lib/libruby1.8.so.1.8
rb_yield_values () from /usr/lib/libruby1.8.so.1.8
rb_ary_each () from /usr/lib/libruby1.8.so.1.8
rb_funcall2 () from /usr/lib/libruby1.8.so.1.8
rb_iterate () from /usr/lib/libruby1.8.so.1.8
rb_block_call () from /usr/lib/libruby1.8.so.1.8
No idea if this is of any use ...
I''ve also tried using --debug, but no debug statements are printed
either during the entire time puppetd is hogging the CPU.
Will have a second look though, maybe something interesting is printed
earlier...

Another common answer is to try combining exec and rsync. I ended up using

This part of the process doesn''t know getting the checksum is unnecessary (in fact this is the same code that is used to serve file metadata over the wire, except in this case it is locally executed). This isssue seems to be frequently raised, so I think I''ll work on it, if I have some spare time soon. -- Brice Figureau Follow the latest Puppet Community evolutions on www.planetpuppet.org! -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Bug 3170 seems to suggest checksum => undef should work though? Anyway, it would indeed be great if this were solved. I wish I understood Ruby, would love to peek under the hood of puppet...

The checksum are needed when remotely fileserving (and sometimes locally), thus they are also computed when managing local (not sourced) files, because the same code is run.> Bug 3170 seems to suggest checksum => undef should work though?It used to work in 0.24.x, but we lost this in 0.25 when the whole file serving system was refactored (and greatly improved despite what you found).> Anyway, it would indeed be great if this were solved.I concur. This is annoying. I have a 5 minutes hack to disable checksumming, but it far from being production ready. I don''t think I''ll have time this week-end to work on this, but if I can find 5 minutes, I''ll try to send a preliminary patch to puppet-dev.> I wish I understood Ruby, would love to peek under the hood of > puppet...I learnt ruby by fixing bugs in Puppet.

I know this isn''t what you want, but how about adding chown to the Makefile used to generate the deb. Also, you could just run chown using Exec. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

To get rid of the unwanted log message at the expense of slower execution, add onlyif => "some command to check whether there''s a problem", The onlyif command could use something involving "find" to print the names of bad files, and "test" to see whether find''s output was empty. --apb (Alan Barrett) -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Since this is an "always run", why not just puppet a similar script into cron.hourly and lighten puppets involvement?
