I have puppet class to mount a disk on a mount point, if the disk is not mounted it is mounting fine, but if the disk already mounted it is still trying to mount and getting mount point busy error.

Could not evaluate: Execution of '/bin/mount -o defaults,comment=puppet /data/' returned 32: mount: /dev/xvdc is already mounted or /data busy /dev/xvdc is already mounted on /data

How does puppet check if disk is mounted or not? how to over come this issue?

Here is my class looks like:

class local_mount (
      $data_dir = hiera('data_dir','/data/') 
    ) {

      if $::ec2_block_device_mapping_ephemeral1 {
        mount { 'ephemeral_media':
          ensure  => absent,
          name    => '/media/ephemeral1',
          device  => "/dev/${::ec2_block_device_mapping_ephemeral1}",

        mount { 'data_dir_mount':
          ensure  => mounted,
          name    => $data_dir,
          device  => "/dev/${::ec2_block_device_mapping_ephemeral1}",
          atboot  => true,
          options => 'defaults,comment=puppet',
          fstype  => auto,
          dump    => 0,
          pass    => 2,
          require => [Mount['ephemeral_media']],

Could you please post the relevant snippet of your manifest. Are you using an exec or a mount? More details pls.

Are you using the onlyif parameter on the exec type reference?

The Puppet mount provider isn't sophisticated enough to solve this problem. I spent a few days on it last year and never came up with a solution that wasn't a pile of hacks.

I solved it by building AWS AMIs that do not mount any ephemeral storage. Seemed the simplest and cleanest way to go about it.
