I was just reviewing the roadmap again after months and thought I

different.

If i have 10 clients doing afr to 2 servers, and one of the servers is
faster (20 scsi versus 8 sata2), how does afr pick which one to read
data from? some kind of round robin or something?

Uh oh. Maybe I missed reading something.
Does NFS currently not work with glusterfs? I was planning on having a
3 server cluster that exported the mounted glusterfs directory to NFS
on each of the 3 servers.

Haha ok now I have something screwy. Below is my client.vol file.
Now when I mount the cluster and try to create a directory it comes back with
[EMAIL PROTECTED] glusterfs]# ls
one two
[EMAIL PROTECTED] glusterfs]# mkdir three
mkdir: cannot create directory `three': File exists

If I have 3 data servers, and I want to have 2 copies of every file
across the 3 servers using AFR, what would the configs look like
assuming /home/export is where i want to store my data on all 3
servers.
To get a raid 1 do i need as many copies as i have servers, or can i
say only 2 copies
replicates to first
'n' servers if you need a replica 'n'. Currently you need to set up unify
over afr, and export 2 different volumes from each server and get the
required functionality. We are hoping to give this functionality soon.

Are there plans for a command to check the client config for AFR and
make sure you actually have the right amount of copies for whatever
the config specifies?
So if i say *:2 copies and on a 3 server cluster 1 goes down for a
day, now its likely i only have 1 copy of my files, when i bring back

Hopefully one of the devs can answer this.
I just setup a 2 server cluster. server1 has 144 gigs of free space,
server2 has 78 gigs.
I have both set to do the AFR thing and told the config to replicate *
(all files right?) with 2 copies.
So what happens when I get to 80 gigs, will i start
I was wondering if there was any input on best practices of setting up
a 2 or 3 server cluster.
My question has to do with where to run glusterfsd (server) and where
to run glusterfs (mounting as a client).
Should I keep the servers that are actually handling the drives and
exporting the
