Re: mkfs and mdadm support

Finally got around to opening up a couple of tickets on this.  I need to finish up some of the specs, I've been concentrating more on real world testing.  Should be ready to have it pulled in this weekend. Here are a couple quick examples of what it can do so far.

Filesystem provider:

file_system "/dev/sde" do

  device '/dev/sde'

  partitions [

    {'number' => 2, 'type' => 'raid', 'start' => '5GB', 'end' => '10GB'},

    {'number' => 1, 'type' => 'raid', 'start' => '0GB', 'end' => '5GB'}

  ]

  action :partition

end

file_system "/dev/sde1" do

  device '/dev/sde1'

  fs_type  'ext3'

  options '-j'

  action :create_fs

end

file_system "/dev/sde1" do

  device '/dev/sde1'

  fs_type  'ext3'

  action :resize_fs

end

Raid provider:

raid '/dev/md0' do

  device  '/dev/md0'

  raid_devices ['/dev/sdc','/dev/sdd']

  level 1

  action [:create,:assemble]

end

file_system "/dev/md0" do

  device '/dev/md0'

  fs_type  'ext3'

  options '-j'

  action :create_fs

end

raid '/dev/md0' do

  device  '/dev/md0'

  action [:stop]

end

       The way I'm working with EBS volumes on ec2 where I want it to format the EBS device as ext3 *only* if it is not already formatted and then ensure it is properly mounted, I also want to grow the filesystem to fill the space in case i booted from a snapshot with a larger volume size.

Thanks Ezra that gave me another tool I didn't know about, e2label.

So I've got most of a filesystem resource/provider working.  It can create linux/raid/lvm partitions with parted, and then add ext3/xfs filesystems to linux partitions if specified.

Awesome! Have you opened up a ticket for this improvement? Providing the specs are sufficient, I'm happy to include this is 0.7.2 =D

I'll open a ticket for this and the raid resource, I *should* be able to get them mostly finished this weekend.  I have specs for the resources, need to get some for the providers.
