Gluster users - Dec 2009 - What is the best configuration for a compiling farm?

Hello,

I plan to do a small compiling farm.
What would be the best architecture and mode to use?

Initially, I was planning to have one server (which is also
a client) and three other machines which are only clients.

I am asking myself if having all machines acting both as
client and server wouldn't be better.

What I want to avoid is that when a file is read from the server
the bandwidth is shared between clients to access this file.
I'd like to have clients possessing a file help the server to distribute
it to other nodes rather than having the server only serving files.
I don't know if this is the default behavior of GlusterFS.

The usage pattern would be like this I guess: all clients read almost
all files from the source tree, each client produce and write a few files.

Thank you,
Francois.

you can obtain this behavior by using replicate. 3 servers can be run on all
the nodes and clients running on each of these 3 nodes can have a replicate
of 3 children - 3 protocol/client speaking to each of the server - and each
of the client specifying the "read-subvolume" as local server in
replicate.

But since replicate replicates all the data, think of whether you can afford
to maintain 3 replicas of data.
