Sorry, just another question:

- in my installation of gluster 3.7.1 the command gluster features.ganesha
enable does not work:

# gluster features.ganesha enable
unrecognized word: features.ganesha (position 0)

Which version has full support for it?

- in the documentation the ccs and cman packages are required, but they seems
not to be available anymore on CentOS 7 and similar, I guess they are not really
required anymore, as pcs should do the full job

Thanks,

	Alessandro
