Chef-client (still) randomly failing

philcryer · November 19, 2013, 6:13pm

I’m still failing to get chef-client to run on it’s own without failing due
to timeouts. I have 4 CentOS 6.4 nodes in QA, overnight usually 2 will fail
and show as ‘red’ the next day - it runs hourly, so they’ll be down for 10+
hours. I login to the node, stop chef-client, run it manually, and it
works.

Why is it timing out on NTP, and even failing as it retries 4 times in a
row?
Why doesn’t it fix itself on the next run? It seems to fail, and then
never recover.

Full logs here:chef-client keeps randomly failing. I login to the node, stop chef-client, run it manually, and it works. 1) Why is it timing out on NTP, 4 times in a row? 2) Why doesn't it fix itself on the next run? It seems to fail, and then never recover. · GitHub

Can you check lsof and ps to see if there is a child process of chef that does not get killed and keeps the yum lock?

You may be hitting this issue: https://tickets.opscode.com/browse/MIXLIB-16

That’s been fixed in master and should get released with the next Chef 11.x release. You could try building the gem manually and installing it on one of your systems to see if it fixes the problem which would be greatly appreciated.

Can do Daniel, can you tell me how I build the gem manually? I've checked
out from GitHub - chef-boneyard/chef-client: Development repository for Chef Client cookbook and
GitHub - chef-boneyard/chef: DEPRECATED: Use chef-client or chef-server - have run Bundle install
successfully, but don't see any info about how to build the gem. And, can I
just build the chef-client 11 gem, and put it on an existing node that's
still talking to chef-server 10.x? Thanks

You need to build the mixlib-shellout gem from master to get the fix: GitHub - chef/mixlib-shellout: mixin library for subprocess management, output collection

The process should be:

git clone
bundle install
rake gem

and then you have a gem package under pkg.

I may push a prerelease version a little later today (chatting with the team about this now). If that happens you would just do /opt/chef/embedded/bin/gem install mixlib-shellout —pre (assuming omnibus). I’ll let you know what we decide.

Ok, I've got that in place on my qa01 - I did a chef-client stop, then a ps
to make sure all chef processes were gone, so we'll see how this one goes.
If you do a prerelease I can install it on another node, just let me know -
and thanks.

Daniel, sorry to say this still fails with the new mixlib-shellout. It
fails, then fails every other time chef-client runs and never works. I
think it may still be an issue with the yum.pid getting in the way. To fix,
I ssh in and do:

-> stop chef-client

/etc/init.d/chef-client stop

Stopping chef-client: [ OK ]

-> make sure all chef process are done

ps -fe|grep chef

root 14303 14279 0 13:29 pts/0 00:00:00 grep chef

-> remove the stale yum pid

rm /var/run/yum.pid

-> run chef-client

chef-client

And it just works. So, here are the logs from when it was failing, notice
it continued to try every hour...

I would expect these error messages to look different with the new version of mixlib-shellout. Can you run this recipe:

require 'mixlib/shellout/version'
log "the shellout version is #{Mixlib::ShellOut::VERSION}" do
level :warn
end

With chef-apply: chef-apply shellout-version.rb

the output should look like:

Recipe: (chef-apply cookbook)::(chef-apply recipe)

log[the shellout version is 1.3.0.rc.0] action write[2013-11-21T11:49:45-08:00] WARN: the shellout version is 1.3.0.rc.0

So is there a live process that has the yum lock? Or it’s truly stale and the pid in the file is a dead process? Also is this machine tight on RAM, and is there anything in the OOM killer log? At first glance I can’t think of what chef could do automatically for that case. Perhaps it could read the pid file and check if the process is alive, but that seems fraught with peril and prone to race conditions.

In any case if there are not any stale yum-dump.py processes hanging around then this behavior isn’t caused by MIXLIB-16, so I might have sent you on a wild goose chase.

philcryer · November 22, 2013, 6:09pm

so nothing I can see is locking yum, assuming it's something chef is
kicking off. What I do (when things aren't working) is login, stop
chef-client, kill any chef processes hanging around and make sure there's
no /var/run/yum.pid. Then I manually run chef-client, it works fine. I do
it again to be sure it can still work, that's fine, then I loggout. hours
later, it's stuck, in this condition again. This is across 4 VMware VMs,
each are just running apache and php, each has 2Gig RAM. They're CentOS
6.4. I want to get it fixed because I want chef-client to check in
regularly so I have all green when I run knife status. Anything else you
can think of to debug what's happening to make it fail (seemingly)
randomly? Thanks

But the constant here is that there’s always a /var/run/yum.pid and there is no process matching that pid (or it’s been recycled)? If that’s the case, the next step is to figure out what process that is, and why it’s dying without cleaning up after itself.

-> make sure all chef process are done

ps -fe|grep chef

root 14303 14279 0 13:29 pts/0 00:00:00 grep chef

-> remove the stale yum pid

rm /var/run/yum.pid

-> run chef-client

chef-client

And it just works. So, here are the logs from when it was failing, notice it continued to try every hour...

So is there a live process that has the yum lock? Or it’s truly stale and the pid in the file is a dead process? Also is this machine tight on RAM, and is there anything in the OOM killer log? At first glance I can’t think of what chef could do automatically for that case. Perhaps it could read the pid file and check if the process is alive, but that seems fraught with peril and prone to race conditions.

In any case if there are not any stale yum-dump.py processes hanging around then this behavior isn’t caused by MIXLIB-16, so I might have sent you on a wild goose chase.
