doc: Move admin-guide to markdown format.

Editing markdown is probably more easier than xml.

pandoc can then be used for conversion to html, pdf and any other necessary
formats. Note that pandoc has the following input and output formats:

Input: markdown and (subsets of) Textile, reStructuredText, HTML, LaTeX, and
DocBook XML.

Output:plain text, markdown, reStructuredText, XHTML,  HTML  5,  LaTeX
(including beamer slide shows), ConTeXt, RTF, DocBook XML, OpenDocument XML,
ODT, Word docx, GNU Texinfo, MediaWiki markup, EPUB, Textile, groff man pages,
Emacs Org-Mode, AsciiDoc, and Slidy, Slideous, DZSlides, or S5 HTML slide shows.
It can also  pro‐ duce PDF output on systems where LaTeX is installed.

All documentation changes can be submitted as changes to markdown and we can
attempt a periodic documentation refresh on gluster.org.

+Setting up Trusted Storage Pools
+================================
+
+Before you can configure a GlusterFS volume, you must create a trusted
+storage pool consisting of the storage servers that provides bricks to a
+volume.
+
+A storage pool is a trusted network of storage servers. When you start
+the first server, the storage pool consists of that server alone. To add
+additional storage servers to the storage pool, you can use the probe
+command from a storage server that is already trusted.
+
+> **Note**
+>
+> Do not self-probe the first server/localhost.
+
+The GlusterFS service must be running on all storage servers that you
+want to add to the storage pool. See ? for more information.
+
+Adding Servers to Trusted Storage Pool
+======================================
+
+To create a trusted storage pool, add servers to the trusted storage
+pool
+
+1.  The hostnames used to create the storage pool must be resolvable by
+    DNS.
+
+    To add a server to the storage pool:
+
+    `# gluster peer probe `
+
+    For example, to create a trusted storage pool of four servers, add
+    three servers to the storage pool from server1:
+
+        # gluster peer probe server2
+        Probe successful
+
+        # gluster peer probe server3
+        Probe successful
+
+        # gluster peer probe server4
+        Probe successful
+
+2.  Verify the peer status from the first server using the following
+    commands:
+
+        # gluster peer status
+        Number of Peers: 3
+
+        Hostname: server2
+        Uuid: 5e987bda-16dd-43c2-835b-08b7d55e94e5
+        State: Peer in Cluster (Connected)
+
+        Hostname: server3
+        Uuid: 1e0ca3aa-9ef7-4f66-8f15-cbc348f29ff7
+        State: Peer in Cluster (Connected)
+
+        Hostname: server4
+        Uuid: 3e0caba-9df7-4f66-8e5d-cbc348f29ff7
+        State: Peer in Cluster (Connected)
+
+Removing Servers from the Trusted Storage Pool
+==============================================
+
+To remove a server from the storage pool:
+
+`# gluster peer detach`
+
+For example, to remove server4 from the trusted storage pool:
+
+    # gluster peer detach server4
+    Detach successful
