Scalarium's EBS cookbook with added magic

chef-ebs

This is a cookbook that makes it easy to create/attach EBS volumes, and create filesystems and RAID arrays on them.

Usage

RAID Array Creation

Add recipe[ebs] to your run list, and configure these attributes:

Create a RAID 10 across four 10GB volumes each with 2000 provisioned iops, make it an lvm logical volume, format it with XFS, and mount it on /data.

{
  :ebs => {
    :raids => {
      '/dev/md0' => {
        :num_disks => 4,
        :disk_size => 10,
        :piops => 2000,
        :raid_level => 10,
        :fstype => 'xfs',
        :mount_point => '/data',
        :uselvm => true,
      }
    }
  }
}

Use Existing Volumes for RAID Array

Add recipe[persistent] to your run list, and configure these attributes:

Create a RAID 10 across the volumes specified in the persistent_volumes array, do not use LVM, format it with XFS, and mount it on /data.

{
  :ebs => {
    :raids => {
      '/dev/md0' => {
        :raid_level => 10,
        :fstype => 'xfs',
        :mount_point => '/data',
        :uselvm => false,
        :persistent_volumes => [
          "vol-xxxxxxxx",
          "vol-xxxxxxxx",
          "vol-xxxxxxxx",
          "vol-xxxxxxxx"
        ]
      }
    }
  }
}

EBS Volume Creation

Create a 10GB volume with 1000 provisioned iops, format it with XFS, and mount it on /data with noatime as an option.

{
  :ebs => {
    :volumes => {
      '/data' => {
        :size => 10,
        :piops => 1000,
        :fstype => 'xfs',
        :mount_options => 'noatime'
      }
    }
  }
}

mount_options are optional and will default to noatime,nobootwait on all platforms except Amazon linux, where they will default to noatime.

Credentials

Expects a credentials databag with an aws item that contains aws_access_key_id and aws_secret_access_key.

You can override the databag and item names with node[:ebs][:creds][:databag], and node[:ebs][:creds][:item], but the key names are static.
