[Gluster-users] how to configurate hard disk usage

[Yaoxing]

Hi all,
I'm new to GlusterFS. I read the documents, and I can tell the setup is
very easy. The only problem is I can't find where I can specify which
hard disk GlusterFS uses. Does it use up all my disks? because I'd like
to reservce some space for disk cache and other programs. How can I
configurate this please?
