[chef] Re: Re: Re: How to format a volume and mount after using aws_ebs_volume

[Gregory Symons < >]

Well, the second execute could be a directory resource. For detecting if the volume is formatted, you can use blkid. That's what the lvm_logical_volume provider in the lvm cookbook does. Or, if you're willing to use LVM, just use the lvm cookbook to do it:

lvm_volume_group 'vg-data' do

   physical_volumes '/dev/sdi'

   logical_volume 'data' do

      size '100%VG'

      filesystem 'ext3'

      mount_point '/data'

   end

end

Hi is what I used...seemed to work but I am not too happy about the execute blocks.  Any way to make more pretty?



include_recipe "aws"
data_bag("my_data_bag")
db = data_bag_item("my_data_bag", "my")
aws = db['development']['aws']

aws_ebs_volume "db_ebs_volume" do
  aws_access_key aws['aws_access_key_id']
  aws_secret_access_key aws['aws_secret_access_key']
  size 50
  device "/dev/sdi"
  action [ :create, :attach ]
end

execute "format_vol" do
  command "sudo mkfs.ext3 /dev/xvdi"
  action :run
  not_if {File.exists?("/data")}
end
execute "mkdir_data" do
  command "sudo mkdir /data"
  action :run
  not_if {File.exists?("/data")}
end

mount "/data" do
  device "/dev/xvdi"
  fstype "ext3"
  action [:mount, :enable]
end

Hi,

I used the below to attach a volume to an ec2 isntances.


aws_ebs_volume "db_ebs_volume" do
  aws_access_key aws['aws_access_key_id']
  aws_secret_access_key aws['aws_secret_access_key']
  size 50
  device "/dev/sdi"
  action [ :create, :attach ]
end

I need to now format the volume

create a directory called /data

then mount the the volume with the /data directory.

What is the best chefonic method to achive this is a recipe?

I have tried this before, and I called out to shell to do invoke mkfs. Problem arises when you want ext3/ext4 -- the ext3utils don't give you a way to test whether a volume is formatted before you reformat it :-/ mkfs.xfs will, however, return a non-zero exit code that you can use.

For mounting, you can use the built-in mount resource.
