+**NOTE:** I pulled the plug on this to test if they all at least saw the power going down.  Now that I think about it, archon is going to need to go down first, so I'll need to modify the battery time left on the slave so it goes first.

 ==== Raid5 Build ====
+=== My Notes Take II ===
+I had the old Hitachi 500gb drive that used to be my MST3k repository die, so I think I'm going to go with a clean and unencrypted raid this time around (now that I know how to do it, I'd rather have the speed).
+Creation Date:   --- //[[david@lattice.net|David Lloyd Rabine]] 2008/10/16 06:45//
+  - Turned off the server, and swapped out the Hitachi with the new Seagate ES.2 500gb drive.
+  - Create a partition on the new drive (just take up the entire disk) with **fdisk** on each as the primary partition.
+  - Use **mdadm** to create the array <code>
+mdadm --create /dev/md0 --chunk=64 --level=5  --name=spaceraid --raid-devices=5 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1
+</code>
+  - Format the device as ext3:  <code>
+mkfs.ext3 -m 0 /dev/md0 -L /space # I am not leaving any reserve since this is a data drive only
+</code>
+  - Mount the raid <code>
+mount /dev/md0 /mnt/raid/space/
+</code>

+===== gallery =====
+I wanted to install the newest Gallery BETA software to store photos and videos online.  I'm migrating this to sage as this is the faster, better machine at the moment (until Slackware 13 arrives and the big re-install on archon...)  This needed a more recent PHP, so I followed some instructions online to install a "testing" version of CentOS 5.
+  * Page where I found HOWTO: [[http://www.freshblurbs.com/install-php-5-2-centos-5-2-using-yum]]
+  * Photo Repository:
+==== Update PHP ====
+  - Added the "testing" repository to sage by editing **** and putting this in it:  <code>
+[c5-testing]
+name=CentOS-5 Testing
+baseurl=http://dev.centos.org/centos/5/testing/$basearch/
+enabled=0
+gpgcheck=1
+gpgkey=http://dev.centos.org/centos/RPM-GPG-KEY-CentOS-testing
+</code>
+  - Update just PHP by enabling the repository temporarily:  <code>
+yum --enablerepo=c5-testing update php
+</code>
+  - Restart the webserver once PHP is installed:  <code>
+service httpd restart
+</code>
+==== Gallery 3 Beta 2 Install ====
+  - Download the .zip file
+  - I made a virtual host to:  [[http://gallery.rabine.org]]
+    - Modified the named configuration files and added **gallery.rabine.org**
+    - Added **/etc/httpd/conf/sage_virtual_hosts.conf** and configured the remote named virtual host
+  - Created a directory on the raid to store all the data
+  - Had to disable SELinux (probably a rule I could have used to allow it... but I'm being lazy) for apache to see the raid drive directory!?  See this link [[http://forums.devshed.com/apache-development-15/documentroot-does-not-exist-when-it-does-526847.html]]
