[Gluster-users] What is TCP/4007 for ?

[nico at furyweb.fr]

Thanks for reply, I can show this usage with lsof on some 3.12.15 clients :

# ps -ef | awk '/[g]lusterfs/ {print $2}' | xargs -n 1 lsof -p | grep -w 4007
glusterfs 28011 root    7u  IPv4          205739452      0t0      TCP traitNetVM1:49148->glusterVMa:4007 (SYN_SENT)
glusterfs 49535 root    7u  IPv4          205739406      0t0      TCP traitNetVM1:49150->glusterVMa:4007 (SYN_SENT)
glusterfs 92903 root    6u  IPv4          205738745      0t0      TCP traitNetVM1:49151->glusterVMa:4007 (SYN_SENT)
glusterfs 96465 root    6u  IPv4          205739411      0t0      TCP traitNetVM1:49149->glusterVMa:4007 (SYN_SENT)

I am not aware of port 4007 usage in entire Gluster. Not aware of any dependent projects too.

Does anybody have info about this port, is it mandatory, is there any way to disable it if so ?

I have several Gluster clients behind firewalls and opened 24007:24008,49152:49241 to gluster servers. 

I recently found that TCP/4007 is blocked from clients to servers but found this port reference nowhere on google search. 

On server side there's no process listening on TCP/4007 so I would like to disable it on client side, maybe a volume setting should be initialized. 

Gluster servers are 5.1 
Volumes are replica 3 with arbiter 
Clients are 3.12.15 (Wheezy) or 4.1.5 (Jessie/Stretch) 

I thank anyone able to give me some information.
