Differents file systems are supported by a collections of GFAL 2 plugins, this is a non complete list:

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.

• gfal2-plugin-gridftp
• gfal2-plugin-lfc

• gfal2-plugin-rfio
• gfal2-plugin-dcap
• gfal2-plugin-http
• gfal2-plugin-xrootd

For convenience we provide a package called gfal2-all, which will trigger the installation of all these packages.
gfal2-devel is required only for development.
A typical installation can be done as easy as bellow:
