[Samba] Cannot Write to Linux Shares from Mac

[Hal Vaughan]

I have a Linux server and this is my output from smbstatus:

I have two Samba shares on the system.  One is intended to be read-only and the other read-write.  Here are the share portions of my smb.conf file:

[Library]
	comment = Media library
	path = "/share01/Library"
	browseable = yes
	read only = yes
	guest ok = yes
#	follow symlinks = yes
	wide links = yes

[MediaShares]
	comment = Non-guest share for file manipulations
	path = "/share01"
	browseable = yes
	writeable = yes
	guest ok = no
	create mask = 0644
	directory mask = 0755
#	follow symlinks = yes
	wide links = yes

(The commented out follow simlinks is for testing some things - not in use now.)

The idea is that most of my family’s computers can read the Library share and play video and music files and so on.  On my iMac, I can access MediaShares, the parent directory to the Library share.  MediaShares is supposed to be read/write so I can manage the library and add new content. The directories are read/write for me, as a user.  I can write to them on the Linux server.

My desktop is an iMac, running macOS 10.14.3.  I can mount MediaShares and give it my password, but it’s no longer writeable.  It was a month or so ago, but now that I’m trying to rip more CDs to the media library, I can’t write to MediaShares at all from my iMac.

In the past, I had the share auto-mounting, without even asking for my password, but now, when I mount the MediaShares volume, I have to do it by hand and use my password.

How can I make this volume mount R/W from my iMac and what probably changed things so it was no longer auto-mounting or letting me write to it?
