<h2>Description</h2>
<p>
The Grid File Access Library 2 offers a POSIX interface to the distributed files system supported by WLCG.<br />
Differents file systems are supported by a collections of GFAL 2 plugins, this is a non complete list:
</p>
<ul>
<li>GRIDFTP with gsiftp://</li>
<li>LFC (Logical File Catalog), with lfn://</li>
<li>SRM (Storage Resource Manager) with srm://</li>
<li>RFIO (Remote File I/O) with rfio://</li>
<li>DCAP (Remote FTP for dCache ) with gsidcap://</li>
<li>HTTP/Webdav with cluster, third party copy and client side credential support</li>
<li>XRootD protocll with root://</li>
<li>S3 and Google Cloud, with s3:// and gcloud://.</li>
</ul>
</p>
<h2>Installation</h2>
<p>
GFAL2 itself abstracts the access to different underlying storage systems - including local -, but in order to get
support for a given protocol, its corresponding plugin needs to be installed.
</p>
<ul>
<li>gfal2-plugin-gridftp</li>
<li>gfal2-plugin-lfc</li>
<li>gfal2-plugin-srm</li>
<li>gfal2-plugin-rfio</li>
<li>gfal2-plugin-dcap</li>
<li>gfal2-plugin-http</li>
<li>gfal2-plugin-xrootd</li>
<li>gfal2-plugin-file</li>
<li>gfal2-plugin-mock</li>
</ul>
<p>
For convenience we provide a package called gfal2-all, which will trigger the installation of all these packages.<br />
gfal2-devel is required only for development.<br />
A typical installation can be done as easy as bellow:
</p>
<pre>yum install gfal2-all gfal2-devel</pre>
