I all,
I have some problem with automatic file translator ( afr). I have two server
A e B. Both servers have afr client configured.

If I stop one server, for example B, The file system managed from AFR is not
available for 30 sec in the server A.

 Below there is the gluster-client.vol of one of the server.

  volume TSU-1.localdomain-disk
          type protocol/client
          option transport-type tcp/client
          option remote-host 127.0.0.1
          option remote-subvolume disk
  end-volume

  volume TSU-2.localdomain-disk
          type protocol/client
          option transport-type tcp/client
          option remote-host 10.1.48.51
          option remote-subvolume disk
          option transport-timeout 5
  end-volume

  volume disk-afr
          type cluster/afr
          subvolumes TSU-1.localdomain-disk TSU-2.localdomain-disk
          option favorite-child TSU-1.localdomain-disk
  end-volume

  volume writeback-disk
          type performance/write-behind
          option aggregate-size 131072
          subvolumes disk-afr
  end-volume

  volume readahead-disk
          type performance/read-ahead
          option page-size 65536
          option page-count 16
          subvolumes writeback-disk
  end-volume

the server has the following configuration:
##### Volume #####

  volume local-disk
          type storage/posix
          option directory /glusterfs/shared
  end-volume

  volume disk
          type features/posix-locks
          subvolumes local-disk
  end-volume

##### Access Control #####

  volume server
          type protocol/server
          option transport-type tcp/server
          subvolumes disk
          option auth.ip.disk.allow *
  end-volume

Is there a way to avoid this behaviour?
Thanks
Maurizio
