Re: [Puppet Users] Mounting Swap

[Jens Braeuer]

Hi,

this is how I enable/disable swap. I tested it on RHEL5 and RHEL6, but it 
should work on all linuxes I guess.

swap { "swap": }
swap { "swap": ensure => absent }

define swap($ensure = present) {
  if $ensure == present {
    exec { "swap-on":
      command => "swapon -a",
      unless => "grep partition /proc/swaps"
    }
  } else {
    exec { "swap-off":
      command => "swapoff -a",
      onlyif => "grep partition /proc/swaps"
    }
  }
}

Cheers,
Jens
