Re: [Puppet Users] Using Puppet for downgrading Varnish (circular dependency)

2013-09-17 Thread Nikolay Mishin 
Hello!
Help me please
how do I get puppet to downgrade several packages at the same time?
I want to downgrade to samba 3.6.9 to 3.5.10
for this I am writing yum downgrade samba-winbind-3.5.10, 
samba-common-3.5.10, samba-common-clients-3.5.10
and how do I get puppet to do the same?
is it possible?
Thank you!

 Hi Wolf,

 indeed that 'exec' solution is what I've found when searching for a 
 solution.
 In my situation this won't help - unfortunately.

 Nevertheless I tracked down the main problem to be caused by different
 usage scenarios for yum.

 When upgrading I have to specify only the main varnish package 'varnish'.
 When downgrading I have to specify both the 'varnish' and the 
 'varnish-libs'
 package for yum.

 As long as puppet does not support both options we will have to use work-
 arounds. ;-)

Re: [Puppet Users] Using Puppet for downgrading Varnish (circular dependency)

Hi Stefan,

I've run into similar issues before… I don't have module code handy, but
what I ended up doing was creating an exec which performed something
similar to:

exec{'nuke_pesky_pkg':
  command = 'rpm -e $package; touch /etc/package.removed',
  creates = '/etc/package.removed'
}

which I run before the package declaration..

I imagine others might have better suggestions?

 Hi all,

 I am trying to use puppet (2.7.18) for downgrading varnish cache on Centos
 Linux (6.3).

 Unfortunately there are two varnish RPMs (which seem to have circular
 dependencies):

 varnish-3.0.4-1.el6.x86_64
 varnish-libs-3.0.4-1.el6.x86_64

 When using ensure for downgrading I get a bunch of errors:

 err: /Stage[main]/Varnish/Package[varnish-libs]/ensure: change from
 3.0.4-1.el6 to 3.0.3-1.el6 failed: Could not update: Execution of
 '/usr/bin/yum -d 0 -e 0 -y downgrade varnish-libs-3.0.3-1.el6' returned 1:

varnish-libs = 3.0.4-1.el6
Downgraded By: varnish-libs-3.0.3-1.el6.x86_64 (varnish-3.0)

varnish-libs = 3.0.3-0.rc1.el6
  You could try using --skip-broken to work around the problem
  You could try running: rpm -Va --nofiles --nodigest

 Whatever I try I do not succeed. My goal is to have a rock-solid puppet
 manifest for switching between varnish versions in development environments
 without having to reinstall the whole VM.

 Using yum to downgrade both packages at the same time (and being able to
 resolve circular dependencies) succeeds:

 /usr/bin/yum -d 0 -e 0 -y downgrade varnish-libs-3.0.3-1.el6
 varnish-3.0.3-1.el6

 Any idea how I can solve this?

 Kind regards,
   Stefan
