Did you mean 3.10.12 or 3.12.12?(your initial GlusterFS version)?

If GlusterFS was at v3.10.12, are you sure that you were experiencing issues with samba v4.7.1?

Definitely 3.10.12.  Our production service is still using it:

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

Definitely samba 4.7.1:

root@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.

Actually, yes.  Large numbers of:

[2018/09/12 09:37:17.873711,  0] ../source3/modules/vfs_glusterfs.c:996(vfs_gluster_stat)
 glfs_stat(.) failed: Invalid argument

Might be related to https://bugzilla.samba.org/show_bug.cgi?id=13585.

Can you try installing a version of GlusterFS < 3.12.13 and see if it works normally?

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.
