Volume Setup fails when strict_variables = true & disabled interfaces

[hypnotortoise]

Problematic line in in volume.pp. To find the valid VIP we are parsing through all existing interfaces via facter lookup and matching results from facter lookup for ipaddress_[interface]. However ipaddress_[interface] must not be available for all interfaces found by facter, which results in a undefined variable error.

    $vipif = inline_template("<%= scope.lookupvar('interfaces').split(',').find_all {|x| '${valid_vip}' == scope.lookupvar('ipaddress_'+x) }[0,1].join('') %>")
