Below are suggested parameters to use in smb.conf file of the Samba server to improve operability with Mac OS X clients. Note that some parameters may not work with your version of Samba - read the smb.conf and vfs_fruit man pages (on Linux) for your system. Other than those shown in the [TimeMachineBackup] share below, I recommend you include all parameters in the [Global] section of smb.conf. For ease of copy > paste, a clean smb.conf section is included at the bottom of this page.
Apple extensions ("AAPL") run under SMB2/3 protocol, make that the minimum (probably shouldn't be running SMB1 anyway...) - defaults to SMB2_2 in Samba 4.11+:
min protocol = SMB2
Apple extensions require support for extended attributes(xattr) - defaults to yes in Samba 4.9+:
ea support = yes
Load in modules (order is critical!) and enable AAPL extensions:
vfs objects = fruit streams_xattr
How to store OS X metadata:
fruit:metadata = stream
For additional setting see the manpage vfs_fruit.
Server icon in Finder (added in Samba 4.5):
fruit:model = MacSamba
fruit:veto_appledouble = no ...added in Samba 4.3 fruit:posix_rename = yes ...added in Samba 4.5 fruit:zero_file_id = yes ..added in Samba 4.8 fruit:wipe_intentionally_left_blank_rfork = yes fruit:delete_empty_adfiles = yes
For Spotlight backend indexing using Elasticsearch (added in Samba 4.12):
[share] spotlight backend = elasticsearch
See smb.conf for 4.12 for other Elasticsearch parameters. Gnome tracker is still available (= tracker) or no indexing (= noindex), the default.
For Time Machine backup share (added in Samba 4.8):
[TimeMachineBackup] vfs objects = fruit streams_xattr fruit:time machine = yes
As far as I know, testparm will not validate vfs_fruit parameters. (my server runs an old version of Samba :-), but after you have built your smb.conf, you can check for errors anyway with
#: testparm or
#: testparm -v (which will give you the defaults as well.
Here is the smb.conf code - NOTE - THIS IS NOT A COMPLETE SMB.CONF!!!
[Global] min protocol = SMB2 vfs objects = fruit streams_xattr fruit:metadata = stream fruit:model = MacSamba fruit:posix_rename = yes fruit:veto_appledouble = no fruit:wipe_intentionally_left_blank_rfork = yes fruit:delete_empty_adfiles = yes [TimeMachineBackup] vfs objects = fruit streams_xattr fruit:time machine = yes # fruit:time machine max size = SIZE
From Finder, connect to your Samba server using
Note that TM backups over smb may now be possible with your server.
Other Mac models can be found in
/System/Library/CoreServices/CoreTypes.bundle/Contents/Info.plist. Use "Quick Look", Xcode or plutil to view or convert plist.
File Permission issues
Setting the global option
fruit:nfs_aces = no will prevent macOS clients from modifying the UNIX mode of directories using NFS ACEs. An Access Control Entry (ACE) is part of the Access Control List (ACL).
fruit:nfs_aces = no makes sense if you use standard POSIX ACLs, rather than NFSv4 ACLs (the Linux implementation is called RichACL and is not part of the kernel).
