[Gluster-users] Ideal GlusterFS Setup/config?

[sal poliandro]

Hello all!

Sorry in advanced for the noob questions to follow.

I have implemented Gluster over private GigE to sync files between my two
web servers.  The plan is in the future to add more webservers and set these
two boxes up as dedicated glusterFS boxes but for now they also need to be
serving the content they are duplicating.  I am noticing small lag when we
have more then a few hundred active visitors to the site and need to figure
out where its coming from before football season official gets into swing
when we will have 8000+ unique visitors at any given time.   I am currently
exporting /dev/sda7 as /mnt/gluster then mounting it using the client on
/home.  I am wondering if I am doing it the in the most efficient way and
what io/thread settings I should look into.  Each of these servers has 4GB
of ram, with plenty of extra memory for cache if needed.  The files don't
change very often (in fact really only when a new image or avatar is
uploaded via the forums) but I don't really know how to tweak gluster yet.
Here is my current configs on both servers, it is exactly the same.

[root at web2 glusterfs]# cat glusterfs-server.vol
volume brick
    type storage/posix
    option directory /mnt/gluster
end-volume

volume server
    type protocol/server
    option transport-type tcp/server
    subvolumes brick
    option auth.ip.brick.allow 172.16.1.18* # Allow access to brick
end-volume


[root at web2 glusterfs]# cat glusterfs-client.vol
volume brick1
    type protocol/client
    option transport-type tcp/client # for TCP/IP transport
    option remote-host 172.16.1.181   # IP address of server1
    option remote-subvolume brick    # name of the remote volume on server1
    option transport-timeout 10
end-volume

volume brick2
    type protocol/client
    option transport-type tcp/client # for TCP/IP transport
    option remote-host 172.16.1.182   # IP address of server2
    option remote-subvolume brick    # name of the remote volume on server2
    option transport-timeout 10
end-volume

volume afr
   type cluster/afr
   subvolumes brick1 brick2
end-volume

Any help/suggestions would be very much appreciated!
