Definitely 3.10.12.  Our production service is still using it:

root at mfs-01 ~]#gluster --version
glusterfs 3.10.12


Definitely samba 4.7.1:

root at mfs-01 ~]#smbstatus --version
Version 4.7.1


As an experiment, I’ve now upgraded our test machines all the way to gluster 4.1.4, but the symptoms are the same.

This bug does seem to fit the symptoms, however my prod service is already < 3.12.3 and is not normal.

Perhaps my best option is to try downgrading samba to the original version and see if it restores proper function, until a patched version of Gluster is available.  Or just live with slow FUSE-backed SMB for the time being.
