Error messages emited by Samba

Ever since updating from FreeBSD 11 to FreeBSD 12, I have experienced a
problem with samba. While still on FreeBSD 11, I configured a Windows
10 machine to write backups of selected directories to my FreeBSD
machine. That worked perfectly. No problems were detected and
everything was backed up correctly. However, after updating to FreeBSD
12 a problem has arisen. While the backups do apparently succeed
successfully, the screen on my FreeBSD machine fills up with error
messages while the backup is happening. I have attached a copy of the latest error messages.

I posted on the Samba mail forum and received this reply:

You're getting this due to the error code being returned in errno
not being one that Samba expects. Here's the underlying code:

       ret = quotactl(path, cmd, id, qblk);
        if (ret == -1) {
                /* ENOTSUP means quota support is not compiled in. EINVAL
                 * means that quotas are not configured (commonly).
                 */
                if (errno != ENOTSUP && errno != EINVAL) {
                        DEBUG(0, ("failed to %s quota for %s ID %u on %s: %s\n",
                                    (cmd & QCMD(Q_GETQUOTA, 0)) ? "get" : "set",
                                    (cmd & QCMD(0, GRPQUOTA)) ? "group" : "user",
                                    (unsigned)id, path, strerror(errno)));
                }


Looks like your system is returning ENOENT here in errno, not ENOTSUP or EINVAL.

Since this worked correctly on FreeBSD 11, I believe that I can safely assume that something changed drastically between FreeBSD 11 & FreeBSD 12. I did notice that ZFS was updated. Perhaps that is the cause of this.

In any case, I don't know exactly where to report this, so I thought I would start here.
