(fixed) samba fails starting after upgrade to 4.3

EDIT: Fixed it. Had to chmod 755 /var/cache/samba/msg, enable and start nmbd (this was not necessary before?), then samba started without errors.

Hi,

after upgrading samba to 4.3.0-1 and doing a systemctl daemon-reload, samba fails starting. My server is running as a standalone file server, I'm not using any  active directory features (config at the end of post). Here's the output:

[2015/09/09 12:17:19.870069,  0] ../source4/smbd/server.c:372(binary_smbd_main)
  samba version 4.3.0 started.

[2015/09/09 12:17:20.012219,  0] ../source4/smbd/server.c:477(binary_smbd_main)
  At this time the 'samba' binary should only be used for either:
  'server role = active directory domain controller' or to access the ntvfs file server with 'server services = +smb' or the rpc proxy with 'dcerpc endpoint servers = remote'
  You should start smbd/nmbd/winbindd instead for domain member and standalone file server tasks
[2015/09/09 12:17:20.012383,  0] ../lib/util/become_daemon.c:111(exit_daemon)
  STATUS=daemon failed to start: Samba detected misconfigured 'server role' and exited. Check logs for details, error code 22

I tried to do so, enabled and started winbindd, which also failed:

And finally, here's my smb.conf:

   server string = My SMB Server
   hosts allow = 192.168.77. 127.

   log file = /var/log/samba/%m.log

   max log size = 50

   security = user
   invalid users = root

  encrypt passwords = yes
  smb passwd file = /etc/samba/smbpasswd

   dns proxy = no

   load printers = no
   printing = bsd
   printcap name = /dev/null
   disable spoolss = yes

[myfiles]
   path = /srv/myfiles
   comment = myfiles
   browseable = yes
   writable = yes
   valid users = user1,user2,user3
   nt acl support = yes

Good one Vibee. No head scratching for me now.

Thank you, Vibee !
I could solve same problem. In my case, I did  chmod 755 /var/cache/samba/msg, and start smbd.service instead of samba.service.
That works fine for me.

Re: (fixed) samba fails starting after upgrade to 4.3

In my case it was even simplier: already tryed it on Arch Linux x64 setup and Arch Linux ARM setup.

1) To your "smb.conf" add

server services = +smb

2) Check that this path has 0755 permissions

/var/cache/samba/msg

Once done, reload your nmbd and/or smbd service as always using systemctl

The purposed edit was tested starting from "smb.conf.default" file template.

Re: (fixed) samba fails starting after upgrade to 4.3

Thank you all. Once I'd stopped reading 755 as 775, it fixed my issue, too.

Re: (fixed) samba fails starting after upgrade to 4.3

Had the same issue. Fixing the permissions for /var/cache/samba/msg fixed smbd start.

Re: (fixed) samba fails starting after upgrade to 4.3

Have you tried to reboot?
After changing permissions of '/var/cache/samba/msg' if I reboot 'nmbd.service' starts, but 'smbd.service' still fails...
Manually starting 'smbd.service' after boot works again!

This is the only working solution for me:

1) To your "smb.conf" add

server services = +smb

Waiting for a real fix.

Re: (fixed) samba fails starting after upgrade to 4.3

I've tried to edits here but I am still not getting samba working. When I look in /var/cache/samba I don't have msg there but it lets me set the permissions

I've also added:

server services = +smb

But it doesn't seemed to have worked unless it needs to go in a particular spot. If so where should it go?

Re: (fixed) samba fails starting after upgrade to 4.3

Put it in the 'global settings' section, not in the 'share definitions'.

Re: (fixed) samba fails starting after upgrade to 4.3

I experienced the same problem, none of the above fixed anything, what actually solved it was:

sudo rm -rf /var/cache/samba/*

than I restarted the smbd service and everything went fine.

Re: (fixed) samba fails starting after upgrade to 4.3

Out of interest, what are the permissions on the "msg" directory *before* applying the fix?
