[chef] aws_ebs_raid fails on ec2 node, but only when it's rebooted

[Jorge Bianquetti < >]

Hi!

Something strange it's happening with one mongoDB node that needs and
EBS raid with provisioned IOPS, using Chef 10.26.0

First, node creates EBS raid type 10 with two disks without problems,
and then use it to hosts mongoDB databases.

Then, I reboot or stops the  ec2 node.

When the node finished the boot process,  EBS raid devices are
attached to the machine, but when I run chef-client, it fails with
message:

 FATAL: ArgumentError: ruby_block[wait_mongodb_data_raid]
(/var/chef/cache/cookbooks/aws/providers/ebs_raid.rb line 182) had an
error: ArgumentError: You tried to set a nested key, where the parent
is not a hash-like object:
aws/raid//var/lib/mongodb/device_map/sdi1/sdi2/sdi1


Node's info seems right to me:

    "aws": {
      "raid": {
        "/var/lib/mongodb": {
          "raid_dev": "md0",
          "device_map": {
            "sdi1": "vol-6bba1647",
            "sdi2": "vol-bbbb1797"
          }
        }
      },
      "ebs_volume": {
        "sdi1": {
          "volume_id": "vol-6bba1647"
        },
        "sdi2": {
          "volume_id": "vol-bbbb1797"
        }
      }
    }

So, I tried with different aws cookbook versions: 0.101.3  0.101.2
0.100. All fails in the same steps.

Any suggestions?
