Bogus error - Could not evaluate: Unable to support multiple interfaces in a single file #38

ddcrjlalumiere · 2013-05-20T20:41:45Z

OS: CentOS 6.3
Puppet version (client): 2.7.17
Puppet version (master): 3.0.0
puppet-network version: 0.4.0

I got the following error in my Puppet logs, but the interface is only defined once in the manifest. This is an intermittent error, it does not occur in a reproducible fashion AFAICT.

Sun May 19 03:39:24 +0000 2013 /Network_config[lo:6] (err): Could not evaluate: Unable to support multiple interfaces [lo:6,lo:6] in a single file /etc/sysconfig/network-scripts/ifcfg-lo:6

After which a new error popped up (although the odd "method static->loopback" behavior always happens even on "clean" runs):

Sun May 19 04:09:24 +0000 2013 /Network_config[lo:6]/method (notice): method changed 'static' to 'loopback'
Sun May 19 04:09:24 +0000 2013 Puppet::Type::Network_config::ProviderRedhat (err): redhat is in an error state, refusing to flush file /etc/sysconfig/network-scripts/ifcfg-lo:6

Here's the manifest that is generating the ifcfg files.

class proxy::dev {

  network_config { 'lo:1':
    ensure      => 'present',
    family      => 'inet',
    method      => 'loopback',
    ipaddress   => '10.12.16.18',
    netmask     => '255.255.255.255',
    onboot      => 'true',
    reconfigure => 'true',
    }

  network_config { 'lo:2':
    ensure      => 'present',
    family      => 'inet',
    method      => 'loopback',
    ipaddress   => '10.12.16.19',
    netmask     => '255.255.255.255',
    onboot      => 'true',
    reconfigure => 'true',
  }

  network_config { 'lo:3':
    ensure      => 'present',
    family      => 'inet',
    method      => 'loopback',
    ipaddress   => '10.12.16.20',
    netmask     => '255.255.255.255',
    onboot      => 'true',
    reconfigure => 'true',
  }

  network_config { 'lo:4':
    ensure      => 'present',
    family      => 'inet',
    method      => 'loopback',
    ipaddress   => '10.12.16.21',
    netmask     => '255.255.255.255',
    onboot      => 'true',
    reconfigure => 'true',
  }

  network_config { 'lo:5':
    ensure      => 'present',
    family      => 'inet',
    method      => 'loopback',
    ipaddress   => '10.12.16.22',
    netmask     => '255.255.255.255',
    onboot      => 'true',
    reconfigure => 'true',
  }

  network_config { 'lo:6':
    ensure      => 'present',
    family      => 'inet',
    method      => 'loopback',
    ipaddress   => '10.12.16.23',
    netmask     => '255.255.255.255',
    onboot      => 'true',
    reconfigure => 'true',
  }

  network_config { 'lo:7':
    ensure      => 'present',
    family      => 'inet',
    method      => 'loopback',
    ipaddress   => '10.12.16.24',
    netmask     => '255.255.255.255',
    onboot      => 'true',
    reconfigure => 'true',
  }

}

The ifcfg files created all look identical except for the fourth octet of the IP and the virtual interface identifier:

IPADDR=10.12.16.##
DEVICE=lo:#
ONBOOT=yes
BOOTPROTO=loopback
HOTPLUG=yes
NETMASK=255.255.255.255

This sounds like #36, the fix for which was merged yesterday afternoon. Check your network-scripts directory for ifcfg-*.bak or ~ or .swp files, etc. Updating to the latest revision should get rid of this error.

ddcrjlalumiere · 2013-05-21T13:26:32Z

Turns out this is slightly reproducible, it seems to happen the second run after the daemon is started; but not if the daemon is restarted by hand before before the normal splay time.

Check your network-scripts directory for ifcfg-*.bak or ~ or .swp files, etc.

None there, only the desired configurations.

$ sudo ls -1a /etc/sysconfig/network-scripts/*ifcfg*
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth1
/etc/sysconfig/network-scripts/ifcfg-lo
/etc/sysconfig/network-scripts/ifcfg-lo:1
/etc/sysconfig/network-scripts/ifcfg-lo:2
/etc/sysconfig/network-scripts/ifcfg-lo:3
/etc/sysconfig/network-scripts/ifcfg-lo:4
/etc/sysconfig/network-scripts/ifcfg-lo:5
/etc/sysconfig/network-scripts/ifcfg-lo:6
/etc/sysconfig/network-scripts/ifcfg-lo:7

Updating to the latest revision should get rid of this error.

I'll give it a try and report back. Thanks.

FWIW after adding a missing } for 'lo:1': to proxy::dev I get all the interfaces without any errors reported:

Sorry about that, copy and paste error, the actual manifest has the closing brace. Updated the description.

After updating to commit 48e71d1 version I'm seeing this in the logs (sorry for the multiple runs, had trouble importing it completely at first):

Not sure why it is trying to create the interfaces as those files already exist from earlier Puppet runs:

$ sudo ls -1a /etc/sysconfig/network-scripts/*ifcfg-lo\:*
/etc/sysconfig/network-scripts/ifcfg-lo:1
/etc/sysconfig/network-scripts/ifcfg-lo:2
/etc/sysconfig/network-scripts/ifcfg-lo:3
/etc/sysconfig/network-scripts/ifcfg-lo:4
/etc/sysconfig/network-scripts/ifcfg-lo:5
/etc/sysconfig/network-scripts/ifcfg-lo:6
/etc/sysconfig/network-scripts/ifcfg-lo:7

ericsakowski · 2013-05-21T17:10:39Z

I am not able to reproduce this...I'd restart puppet on master and node and then follow this snippet from the puppet-network README if you haven't already:

Note: you many also need to update your master's plugins (run on your puppet master):

puppet agent -t --noop

Or on puppet 2.7/3.x:

puppet plugin download

adrienthebo · 2013-05-22T02:05:42Z

@ddcrjlalumiere to confirm, the existing contents of lo:6 were not different from the other loopback interfaces?

ddcrjlalumiere · 2013-05-22T15:05:44Z

That's correct. Files have only been generated by this module and aside from the DEVICE and IPADDR lines all are identical. I don't have any clues as to why lo:6 gets special treatment :-/

$ sudo cat /etc/sysconfig/network-scripts/ifcfg-lo\:{1,6} | sort | uniq -c
      2 BOOTPROTO=loopback
      1 DEVICE=lo:1
      1 DEVICE=lo:6
      2 HOTPLUG=yes
      1 IPADDR=10.12.16.18
      1 IPADDR=10.12.16.23
      2 NETMASK=255.255.255.255
      2 ONBOOT=yes

I tried restarting the puppetmaster and ensured it had up to date plugins locally, to no avail.

ericsakowski · 2013-05-22T19:58:44Z

As in issue 39, I was finally able to reproduce the 'Provider in an error state' by running a puppet 2.7 client against a puppet 3.0 master:

ericsakowski · 2013-05-22T21:10:02Z

ok that was a red herring...after all this i went back and tested 2.7 node on 2.7 master and still get the same 'error state' and prefetch errors.

ddcrjlalumiere · 2013-05-24T18:15:30Z

I spun up a fresh client to run this manifest against and here's what I got in the logs, none of the interfaces were created:

@ddcrjlalumiere I think that #40 might have fixed this, could you check the latest version of master and see if that resolves your issue?

ddcrjlalumiere · 2013-05-30T22:39:58Z

Yes, the latest version of master seems to have made things happy. Thanks!
