Failure to load mergerfs in Samba

[dumaresq]

Not sure exactly what is wrong, but after a resent update to mergerfs I can no longer mount my merged directory under samba. Oddly NFS still works just fine. I can't find any errors in Samba, but the error that I get in windows when I try to mount is:

The data area passed to a system call is too small.

I thought it might be a permissions issue so I relaxed the permissions but still no luck. I can still mount the "un-merged" file systems so I think it something in the merger code. Let me know what more debugging would help.

I tried this from samba on the same box, and I get a similar message:

smbclient "\myhost\nas" -U myuser
Enter myuser's password:
Domain=[MYDOMAIN] OS=[Unix] Server=[Samba 4.1.16]
smb: > ls
NT_STATUS_BUFFER_TOO_SMALL listing *
smb: >

More information. It seems to have broken in 1.7.0 in 1.6.0 I can mount everything fine in 1.7.0 it fails.

I also tried to mount a "lower" directory, when I use 1.7.0+ I can't even see the mount point in samba.
