Make fact gluster_host suppress the error output, if Resolv.getaddres…

…s does not work at all, e.g. DNS setup not complete during provisioning stage of a VM.

@derjohn Good idea, but wouldn't your rather have this be || nil ? so that the following nil check applies?

[derjohn]

Hm,
there is still uncatched error output, which makes facter error ....

I think that's the way to go. I'll create a new pull request.

Works not:

irb(main):007:0> Resolv.getaddress 'fitze.fatze'
Resolv::ResolvError: no address for fitze.fatze
        from /home/aj/.rbenv/versions/2.1.2/lib/ruby/2.1.0/resolv.rb:93:in `getaddress'
        from /home/aj/.rbenv/versions/2.1.2/lib/ruby/2.1.0/resolv.rb:43:in `getaddress'
        from (irb):7
        from /home/aj/.rbenv/versions/2.1.2/bin/irb:11:in `<main>'

Works:

irb(main):022:0> begin
irb(main):023:1* Resolv.getaddress 'fitze.fatze'
irb(main):024:1> rescue Resolv::ResolvError => e
irb(main):025:1> # psssst
irb(main):026:1* end
=> nil
