[Gluster-users] glusterfs 4.1.5 - SSL3_GET_RECORD:wrong version number

[Davide Obbi]

Hi,

i have enabled SSL/TLS on a cluster of 3 nodes, the server to server
communication seems working since gluster volume status returns the three
bricks while we are unable to mount from the client and the client can be
also one of the gluster nodes iteself.
Options:
/var/lib/glusterd/secure-acceess
  option transport.socket.ssl-cert-depth 3

ssl.cipher-list:
HIGH:!SSLv2:!SSLv3:!TLSv1:!TLSv1.1:TLSv1.2:!3DES:!RC4:!aNULL:!ADH
auth.ssl-allow:
localhost,glusterserver-1005,glusterserver-1008,glusterserver-1009
server.ssl: on
client.ssl: on
auth.allow: glusterserver-1005,glusterserver-1008,glusterserver-1009
ssl.certificate-depth: 3

We noticed the following in glusterd logs, the .18 address is the client
and one of the cluster nodes glusterserver-1005:
[2018-10-09 13:12:10.786384] D [socket.c:354:ssl_setup_connection]

0-tcp.management: server setup failed

I believe that something has changed since version 4.1.3 cause using that
version we were able to mount on the client and we did not get that SSL
error. Also the cipher volume option was not set in that version. At this
point i can't understand if node to node is actually using SSL or not and
why the client is unable to mount

thanks
