puppet seems to be restarting itself very often

I turned on reporting the other day and I''m seeing alot of these when
puppet
runs.  Especially during times when nothing is going on (middle of the night
etc)
Tue Dec 11 12:34:48 -0500 2007
//base/puppet/puppet::client/Service[puppet]/ensure (notice): ensure changed
''stopped'' to ''running''

It''s also quite odd that puppet when it runs it thinks it''s
not running,
seems to be an existential crisis.

Anyone else seen this?

Are you sure it''s actually stopped, and not just a failure in the  
init script or something?

Re: puppet seems to be restarting itself very often

I don''t think it''s stopped at all.  How could puppet detect
that it''s
stopped and restart it if it was stopped?  It just seems to be reporting
that.

In my experience, puppetd doesn''t seem to be capable of restarting
itself through the init
mechanism even when I''m trying to do it on purpose.

What does /etc/init.d/puppet status say when puppet is running?  If you 
don''t have a status option in /etc/init.d/puppet, does your puppet
service
declaration provide a means of checking the status?  How is your puppet 
service declaration written?

Re: puppet seems to be restarting itself very often

init.d/puppet status says it''s running (and indeed it is)
my service declaration is:

    service { "puppet":
        ensure      => running,
        enable      => true,
        hasrestart  => true,
        hasstatus   => true,
        require     => Package["puppet"],
    }

I really don''t think it''s an issue that puppet isn''t
running, it''s obviously
running b/c the reports are being generated and if it wasn''t it
wouldn''t be
able to restart itself anyway.

I''m more thinking there''s something in the reporting that
causes that to be
printed.  I haven''t seen that message during a test run.  I do see it
in my
logs.
But looking at the pid numbers for each process they don''t change so I
don''t
think anything is actually being restarted.

Perhaps a bug in how puppet/puppetmaster looks to determine if it''s
running?

I think when you run it by hand, puppet is able to properly determine the 
status of the service but when it runs as daemon, it isn''t getting that
properly.  Does puppet run as something other than root?

Interface type woes

The following block produces the following errors... is interface
working for redhat machines? Both puppetmaster and client are RHEL5
boxes

    interface { ''10.100.92.91'':
        interface => eth1,
        netmask => ''255.255.255.0'',
        onboot => true
    }

[root@ev-agt64-91 ~]# puppetd --verbose

And the interface doesn''t get configured either

Re: puppet seems to be restarting itself very often

On redhat (possibly others) the init scripts use `pidof -o $$ -o $PPID -o
%PPID`

from man pidof;
       -o     Tells pidof to omit processes with that process id. The
special
              pid  %PPID  can be used to name the parent process of the
pidof
              program, in other words the calling shell or shell script.

so /etc/init.d/puppet status is not accurate when called from puppet.

Re: puppet seems to be restarting itself very often

Ah yes, I remember being bitten by this pidof() issue when switching to
Mongrel.  We forked from David Lutterkort''s method (posted to this list
a couple of months ago), which creates an init script for each
puppetmasterd process.

We resorted to cloning the status() function from
/etc/rc.d/init.d/functions, and modifying it so that is greps for
something more substantial.  This was necessary on RHEL4, on RHEL5 I can
see the use of pidof -o but I haven''t tested it.

Anyway, that''s more of an FYI for those interested in poking around.

More practically, you ought to be able to fix it by using

hasstatus => false, pattern => ''puppetd''

That''ll be puppetd checking for itself, so it will always be true
though, unless you run standalone (puppet --blah).  So you may want to
ask if you need this resource at all if you need "ensure =>
running" at
all.

Cheers,
Derek

0.23.2 needs patches to work. Look for "interface" keyworded

This doesn''t seem to work, I''m still getting those messages in
the logs.

Interestingly though service puppet status reports 1 (and only 1) pid.

does puppetd fork to do a configuration run and at that time the status is
being checked?

I guess it''s kinda silly to ensure => running for puppetd since
it''s puppetd
that''s doing the checking.

It can be quite handy, if one is running puppetd from the installer to ensure 
that puppetd is really running.
