(B	
(B	Hi people, 
(B	
(B	I would like to install gfarm in some test machines. 
(B	I've been trying to find a good documentation with no 
(B	luck. I have some questions because a lot of things 
(B	where not clear to me. What I have already done is to 
(B	create a metadata server, and 2 different nodes. When I 
(B	try to mount this gfarm using fuse, the filesystem is 
(B	mounted, but I get errors in df command (from the 
(B	client machine) and I get errors when I try to write 
(B	files in the gfarm mount point:
(B	    - # touch a
(B	STATFS: /: no filesystem node
(B	
(B	What I would like to understand are:
(B	
(B	- What is the purpose oti the gfarm_agent?
(B	- What is the correct method to register a node. At the 
(B	moment I'm using config-gfsd. How do I specify the path 
(B	in the node that will be part of the gfarm ? I tried 
(B	adding     spool /path/to/dir to the gfarm.conf but 
(B	when I run config-gfsd -t it says:
(B	  spool directory    : /var/gfarm-spool
(B	- How do replicas work? Do I have to run gfrep with 
(B	crond? Is it possible to enable replicas by default for 
(B	every newly created file? I found a post in the list 
(B	saying that this is something that would be done in a 
(B	next release.
(B	- I'm totally confused with permissions. If I mount a 
(B	gfarm, can I give to my files permissions of the client 
(B	machine? 
(B	- Is there a complete documentation for installation and usage?
(B	
(B	
(B	What actually I would like to do with gfarm is the following:
(B	I would like to have 2+ nodes in the gfarm filesystem. 
(B	I want each of the client pc to be able to mount a 
(B	diferrent directory in the gfarm: and then, each 
(B	process to be able to use files (write,modify, delete) 
(B	, according to each process ownership.
(B	I want to be sure that whenever a node shuts down 
(B	(because of hardware failure),  the client pcs will 
(B	lose no data and I will be able to add another node and 
(B	rebuild the replicas.
(B	
(B	
(B	thank you for your time,
