Public bug reported:
Using cifs-utils to mount a multiuser SMB mount on Ubuntu Server 16.04
creates random "File name too Long" errors. Issue does not occur if I
mount the share as a single user.
mount opts:
auto,sec=krb5i,multiuser,file_mode=0600,dir_mode=0700,vers=3.0,noserverino,mfsymlinks,_netdev
Issue occurs on
Linux biocompute1 4.4.0-98-generic #121-Ubuntu SMP Tue Oct 10 14:24:03 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
cifs kernel module 2.8
mount.cifs version: 6.4
Issue does not occur on
Linux biocompute2 4.4.0-93-generic #116-Ubuntu SMP Fri Aug 11 21:17:51 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
cifs kernel module 2.8

Debian has caught the bug, this is the exact same behavior and was logged the day before I had my issue:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=880504 . Apparently the issue
I feel like it applies but I'm not familiar with Linux releases, I don't
know if this change was backported all the way to 4.4.0 or if that's
even the right name for that.
Example:
ls: cannot access '/mnt/csfg-fs3/ProjectData/Genozymes/GenozymesShare/HomologyModeling/pdb_files/qs/pdb4qsz.ent.gz': File name too long
directory listing looks like:
drwxr-xr-x 2 awasylyk awasylyk 32768 Jul 2 2015 .
