Perhaps adding SO_KEEPALIVE may help maintain the socket connection in the
event that there's some form of tcp session timeout happening on the
network and/or router (such as in the case of NAT)?
Just a thought.

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
