== Hadoop & GlusterFS ==

 * [http://www.infostor.com/index/articles/InfoStor-Article-Tool-Template/_printArticle/articles/infostor/storage-management/gluster-goes-after-hadoop-big-data.html Gluster Goes After Hadoop Big Data] - GlusterFS 也將變成 Hadoop 支援的底層檔案系統！酷～
{{{
the final release of GlusterFS 3.3 is expected before the end of year 2011. The new release 
provides an integration point for Apache Hadoop enabling Hadoop users to use Gluster for storage.

== OpenNebula ==

 * First, setup ONE_AUTH
{{{
  root@controller> su - oneadmin
  oneadmin@controller> vi $HOME/.one/one_auth
-------------------
oneadmin:<password>
-------------------
}}}
  * start opennebula service
{{{
  root@controller> /etc/init.d/opennebula start
}}}
 * Add a new host (node) in OpenNebula pool
   1. Install 'opennebula-node' debian package in destination host
{{{
  root@node01> apt-get install opennebula-node
}}}
   2. Copy controller ssh key to node01
{{{
  root@controller> su - oneadmin
  oneadmin@controller> cat $HOME/.ssh/id_rsa.pub
  <COPY YOUR CONTROLLER SSH PUBKEY>

  root@node01> su - oneadmin
  oneadmin@node01> vi $HOME/.ssh/authorized_keys
  <PAST YOUR CONTROLLER SSH PUBKEY>
}}}
   3. Test an connection from controller to node01
{{{
  root@controller> su - oneadmin
  oneadmin@controller> ssh oneadmin@node01
    The authenticity of host 'node01 (192.168.0.2)' can't be established. 
    RSA key fingerprint is [].
    Are you sure you want to continue connecting (yes/no)? [yes]
    Warning: Permanently added 'node01,192.168.0.2' (RSA) to the list of known hosts.
  oneadmin@node01>
}}}
   4. Add this host into OpenNebula pool
{{{
  oneadmin@controller> onehost add node01 im_kvm vmm_kvm tm_ssh
}}}
   5. Check node registration on controller
{{{
  oneadmin@controller> onehost list
  ID NAME              CLUSTER  RVM   TCPU   FCPU   ACPU    TMEM    FMEM STAT
   0 node01            default    0    400    388    400    3.9G    2.5G   on
