           default['ephemeral_lvm']['mount_point_properties'] = { 
        
             options: ["defaults", "noauto"], 
        
             pass: 0 
        
           }

the cookbook will just merge the chef attributes set and not overwrite them. For example, with:

    "ephemeral_lvm": {
      "mount_point": "/mnt/mongodb",
      "mount_point_properties": { "options": ["defaults", "noatime","auto"], "paas": 0 }
    }

The end result fstab will be:

/dev/mapper/vg--data-ephemeral0 /mnt/mongodb ext4 defaults,noauto,noatime,auto 0 0

instead of having just the auto (and not both merged on top of each other). Is this intended behavior and/or something to do to fix?

looking at this, it's definitely intentional: https://github.com/rightscale-cookbooks/ephemeral_lvm/blob/master/recipes/default.rb#L69

	default['ephemeral_lvm']['mount_point_properties'] = {
	options: ["defaults", "noauto"],
	pass: 0
	}

fstab merge vs overwrite on defaults
