The upcoming version of euca2ools, version 3, completely reworks the command line suite to make it both easier to write and easier to use. Part 1 of this series discussed the user-facing changes version 3 has to offer, and today we’re going to take a look at how things improve on the developer’s side of the fence.

A change in philosophy: declarative programming

The developer is very much in the driver’s seat in version 1 of euca2ools. To use a car analogy, the developer directly...

In order to use this Ansible playbook on AWS/Eucalyptus, the following is needed:

As we have discussed in previous blog posts, if you want to have High Availability (HA) for the Eucalyptus Storage Controller (SC), you must use the Eucalyptus SAN Adapter and a supported SAN. NOTE: To use Eucalyptus with supported SAN storage, you must decide whether administrative access can be provided to Eucalyptus to control the SAN. If this is possible in your environment, Eucalyptus can automatically and dynamically manage SAN storage.

As of Eucalyptus version 3.2.1,...

This post covers Stage 4, the customer production environment pre-checks and here we will investigate a number of pro-active checks that can be carried out to ensure your servers and network are ready for the Eucalyptus IaaS installation.

In our last blog post, I discussed the storage considerations for the Eucalyptus Walrus component. Toward the end of the post, I talked about pondering some additional implications of using a SAN to back Walrus if you are going to use a Eucalyptus supported SAN with the SAN adapter for the Storage Controller (SC). In this post, we will delve into the various ways you can deploy the Storage Controller (SC) component, building from non-HA to HA with the Eucalyptus SAN adapter. Keep in mind...

今天自己按照网上搜来的教程自己在Ubuntu 12.04上配置了iSCSI Target服务,在这里简单地做个纪录。操作系统是全新安装的Ubuntu 12.04,配置一块500 GB的SATA笔记本硬盘。安装操作系统时将硬盘划分为两个分区,其中一个50 GB的分区(/dev/sda1)挂载为操作系统的根分区;另外一个450 GB的分区(/dev/sda2)作为提供存储服务的空间,暂时不挂载。

安装完操作系统之后,安装必要的软件:

$ sudo apt-get install chkconfig lvm2 iscsitarget iscsitarget-dkms

创建物理卷/dev/sda2:

$ sudo pvcreate /dev/sda2

在物理卷/dev/sda2上创建一个volume group:

$ sudo vgcreate -s 32M vg_target00 /dev/sda2

看一下刚才创建的volume group:

$ sudo vgdisplay --- Volume group...

eustore now supports bootable EBS images

Those of you familiar with Eucalyptus are likely already familiar with the eustore client, which is a utility included with the popular euca2ools.  It allows for the automatic fetching, uploading, and registering of instance-store based images in your Eucalyptus cloud.

It pulls its meta-data and images from http://emis.eucalyptus.com but currently filters on only our most tested images which include Fedora 16/17, Centos 5/6, and OpenSuSe 12.2...
