Intento utilizar las nuevas capacidades de smb (4.8.2) para compartir una unidad con capacidad Time Machine con mi nuevo MBpro 2017 con High Sierra. Puedo hacer que la unidad aparezca en el administrador de TM y agregar correctamente el disco. Sin embargo, cuando ejecuto la copia de seguridad, aparece un mensaje de error típico de Apple no descriptivo:
2018-06-03 11:37:37.677735-0400 localhost backupd[1978]: (TimeMachine) [com.apple.TimeMachine:TMLogInfo] Starting manual backup

¿Alguien sabe lo que significa el error 512?
Aquí está mi smb.conf:
[global]
server string = File Server (smb)
log file = /var/log/samba/log.%m
log level = 3
mdns name = mdns
# Time Machine
vfs objects = catia fruit streams_xattr
fruit:veto_appledouble = no
fruit:encoding = native
fruit:metadata = stream
fruit:aapl = yes
ea support = yes
# Security
server min protocol = SMB2
[TimeMachine]
path = /backup/TM
fruit:time machine = yes
writeable = yes
force group = users
La unidad en sí es un recurso compartido de NFS
