Sorry to followup to my own email but I eventually solved my problem by reformatting the filesystem and copying all the data back to it.  I just couldn't get the security set right.  I could mount the share, but not see any files on it.  From that point I reformatted, without doing anything else, and everything worked fine from then on.

THanks.

Those aren't really the proper answer.  The correct solution is to
label the filesystem for smbd access, or add the desired filesystem
label to the policy.

But I suppose your solution is ok, akin to disabling a firewall
instead of unblocking the one port you need.
