Storage Toolbox (v13 Infinity)

Description

The Storage Toolbox ServerTemplate contains several useful recipes to set up and back up storage within a variety of contexts. It is used within other ServerTemplates to support runbook operations like backup and restore of databases.

Key Features:

• Set up consistent storage blocks on instances or attachable volumes
• Backup using volume snapshots or instance storage snapshots
• Set up continuous backup schedules
• Perform one-off backups with a click of a button
• Save off-site backups in cloud object storage
• Backup and restore across regions and clouds
   

Prerequisites

• 'actor', 'designer', and 'library' user role privileges in the RightScale account

• For Amazon EC2, CloudStack, and other clouds that support security groups, you must have a security group defined with TCP port 22 open for SSH access, the default application port (8000) open to applicable load balancer servers, and any other port and protocol access required by your application. Also, remember that iptables is installed by default on all servers, as described in the Security section of this tutorial.
• Basic understanding of how RightScale's "Database Manager for MySQL 5.x" or  "Database Manager for PostgreSQL 9.1 Beta" ServerTemplates function. 

Technical Overview

The Storage Toolbox ServerTemplate is not designed to launch a server that you can use as-is in a production environment. Instead its purpose is to demonstrate how you can use its scripts to satisfy your own use case. The Storage Toolbox ServerTemplate highlights scripts from RightScale's 'block_device' cookbook. You can use these scripts to build custom ServerTemplates that require the use of storing data in a remote block device (i.e. volume). If the cloud infrastructure does not support the use of block device volumes, the scripts in this ServerTemplate will not apply.

RightScale's own MySQL ServerTemplates leverage many of the same scripts in from the 'block_device' cookbook. However, they can be easily repurposed to satisfy a different use case. This tutorial will explain common examples of how to use the various 'block_device' recipes.
 

• device - A device refers to the storage device that's mounted to an instance for storing data on a non-ephemeral drive. A device can be comprised of a single volume or set of (striped) volumes. The total size of storage that is available for a device is the summation of all the volumes that make up the device. 
• volume - Off-instance storage (disk drive) that persists independently from the life of an instance. A volume can be created from scratch or from a volume snapshot and attached to an instance.
• LVM - Logical Volume Manager is unique to Linux-based instances and allows you to use a group of physical volumes as a single logical volume.

Getting Started

1. Go to the MultiCloud Marketplace (Design > MultiCloud Marketplace > ServerTemplates) and import the most recently published revision of the following ServerTemplate into the RightScale account.
   • Storage Toolbox
2. Use the ServerTemplate to add a server to a deployment and launch the server.
3. Once the server is operational, you can set up a device on the instance using the 'block_device::setup_block_device' operational script.
4. Perform a couple of the other operational scripts to become familiar with the different scripts that are available. 
5. Add the appropriate scripts to your own ServerTemplate for further custom development and testing.

Use Cases

If you plan to use the recipes highlighted in the "Storage Toolbox" ServerTemplate in a custom ServerTemplate of your own, you must remember to make sure that the template has Rightscale's 'block_device' cookbook available from a repository and it must be attached to the template.

Detailed information about how to use each of the following scripts can be found in the Storage Toolbox Runbook:

• block_device::do_primary_backup
• block_device::do_secondary_backup
• block_device::do_primary_backup_schedule_disable
• block_device::do_primary_backup_schedule_enable
• block_device::do_delete_volumes_and_terminate_server
• block_device::setup_block_device
• block_device::do_primary_restore
• block_device::do_secondary_restore
• sys_firewall::setup_rule
• sys_firewall::do_list_rules
