Gluster users - Mar 2011 - GlusterFS 3.1.2 and switch scheduler problem

Hi All,

I'm trying to configure GlusterFS 3.1.2 with cluster/switch xlator. My goal
is to
store data on local disks, and minimize network traffic. I was planing to
have a
directory for every node in GlusterFS root name space, and use switch
scheduler.

I am getting random errors on file creating. Underlying file system is XFS.
Here is the volume file and log excerpt.

Any suggestions?

Thank you.

volume posix
 type storage/posix
 option directory /local/gluster_volumes/test-volume
end-volume

volume locks
  type features/locks
  subvolumes posix
end-volume

volume brick
 type performance/io-threads
 subvolumes locks
end-volume

volume server
 type protocol/server
 option transport-type rdma
 option auth.addr.brick.allow *
 subvolumes brick
end-volume

volume node1
  type protocol/client
  option transport-type rdma
  option remote-host node1
  option remote-subvolume brick
end-volume

volume node2
  type protocol/client
  option transport-type rdma
  option remote-host node2
  option remote-subvolume brick
end-volume

volume cluster-switch
 type cluster/switch
 option lookup-unhashed on
 option pattern.switch.case /node1*:node1;*:node2
subvolumes node1 node2
end-volume
