Well,
with client 3.7.13 compiled on the same machine when I try the same
mount I get:
# mount -t glusterfs sto1.my.domain:BACKUP-ADMIN-DATA /zog/
Mount failed. Please check the log file for more details.
Checking the logs (/var/log/glusterfs/zog.log) I have:

I did not go further about that as I just presumed that 3.7 series was
not compatible with 3.6 servers but it's maybe something else. But here
it is the same client, the same server(s) and the same volume.
The compilation is with features (built with "configure
--disable-tiering" as I don't have installed stuff for that):
FUSE client : yes
Infiniband verbs : no
epoll IO multiplex : yes
argp-standalone : no
fusermount : yes
readline : yes
georeplication : yes
Linux-AIO : no
Enable Debug : no
Block Device xlator : no
glupy : yes
Use syslog : yes
XML output : yes
QEMU Block formats : no
Encryption xlator : yes
Unit Tests : no
POSIX ACLs : yes
Data Classification : no
firewalld-config : no
