[Gluster-devel] afr_open_cbk Error in 1.3.0_pre5.4

[del]

Hello,

I've installed the latest glusterfs on 4 bricks and 2 clients and been
benchmarking it for a while, when I noticed the following in my
glusterfs.log (on the client nodes)

2007-07-20 21:34:00 E [afr.c:696:afr_open_cbk] afr:

I get a lot of these when I create a bunch of 10Kb files in a bunch of
directories. And when I see another bunch of log lines being added
glusterfs IO throughput decreases for a moment, i.e. files are being
created slower.

Here is my glusterfs-client.vol

volume client1
  type protocol/client
  option transport-type tcp/client     # for TCP/IP transport
  option remote-host 10.1.3.115        # IP address of the remote brick
  option remote-port 6996              # default server port is 6996
  option transport-timeout 30          # seconds to wait for a reply
  option remote-subvolume brick        # name of the remote volume
end-volume

volume client2
  type protocol/client
  option transport-type tcp/client     # for TCP/IP transport
  option remote-host 10.1.3.114        # IP address of the remote brick
  option remote-port 6996              # default server port is 6996
  option transport-timeout 30          # seconds to wait for a reply
  option remote-subvolume brick        # name of the remote volume
end-volume

volume client3
  type protocol/client
  option transport-type tcp/client     # for TCP/IP transport
  option remote-host 10.1.3.121        # IP address of the remote brick

  option transport-timeout 30          # seconds to wait for a reply

end-volume

volume client4

  option transport-timeout 30          # seconds to wait for a reply
  option remote-subvolume brick        # name of the remote volume
end-volume

volume afr
  type cluster/afr
  subvolumes client1 client2 client3 client4
  option replicate *:2
  option self-heal on
end-volume


and my glusterfs-server.vol


volume brick
  type storage/posix                   # POSIX FS translator
  option directory /home/export        # Export this directory
end-volume

volume server
  type protocol/server
  option transport-type tcp/server     # For TCP/IP transport
  subvolumes brick
  option listen-port 6996
  option auth.ip.brick.allow * # Allow access to "brick" volume
end-volume

I appreciate any help on this.

Many thanks!
Denis.
