-Automated installer to attach, format and mount an EBS volume.
-This installer assumes that you want the volume formatted as
-an XFS file system. To drive this installer, you need the
-following section in the boto config passed to the new instance.
-You also need to install dateutil by listing python-dateutil
-in the list of packages to be installed in the Pyami seciont
-of your boto config file.
-
-If there is already a device mounted at the specified mount point,
-the installer assumes that it is the ephemeral drive and unmounts
-it, remounts it as /tmp and chmods it to 777.
-
-Config file section::
-
- [EBS]
- volume_id = <the id of the EBS volume, should look like vol-xxxxxxxx>
- logical_volume_name = <the name of the logical volume that contaings
- a reference to the physical volume to be mounted. If this parameter
- is supplied, it overrides the volume_id setting.>
- device = <the linux device the EBS volume should be mounted on>
- mount_point = <directory to mount device, defaults to /ebs>
