[Samba] Mac Cannot unmount Disk Images that are mounted from Samba Shares

[alex]

I am on a Mac OS 12.6.8. 

I have gotten Samba to work great with TimeMachine and general sharing of directories off the server which is running FreeBSD 13.2 with Samba Version 4.16.10.

The one issue I am seeing is that when I have a Mac Disk Image mounted from a Samba share it will not unmount unless I hit the force eject option. 

When I run ‘sudo smbstatus’ on the server I see the mounted disk image is locked:

Locked files:
Pid          User(ID)   DenyMode   Access      R/W        Oplock           SharePath   Name   Time
--------------------------------------------------------------------------------------------------
25419        1001       DENY_NONE  0x20087     RDWR       NONE             /usr/home/alex   test.dmg   Sun Jul 30 13:36:02 2023
25419        1001       DENY_NONE  0x100081    RDONLY     NONE             /usr/home/alex   .   Sun Jul 30 13:36:16 2023


I don’t have any issues with TimeMachine which in theory mounts a disk image from the share and then unmounts it cleanly when it is done with it. Only when I mount a disk image from my home directory. I also tried to make a specific entry in smb.conf to a specific directory with the disk image and saw the same behavior. My conf file is below. Let me know if any other info is needed:



# We want Samba to only log to /var/log/samba/log.{smbd,nmbd}.
# Append syslog at 1 if you want important messages to be sent to syslog too.
  logging = file

# Do something sensible when Samba crashes: mail the admin a backtrace
#   panic action = /usr/share/samba/panic-action %d
