Hi,
A few times a day, syslog gives me:
2025-11-15T12:48:07+01:00 ERR smbd [2025/11/15 12:48:07.565825, 0] ../../source3/modules/vfs_fruit.c:5195(fruit_get_bandsize)

/mnt/user/tm-mark is a Time Machine share (macOS 26.1). Samba 4.23.2 is installed on Unraid OS 7.2.0 (Slackware 15.0+).
/mnt/user/tm-mark/Yavin4.sparsebundle and all the files below are 666 (that’s compliant with the Unraid security model):
root at ohmy:~# ls -la /mnt/user/tm-mark/Yavin4.sparsebundle/

markr is indeed the user Time Machine connects with. Plist looks fine to me:
root at alderaan:~# cat /mnt/user/tm-mark/Yavin4.sparsebundle/Info.plist

Googling gives me no clues how to fix it. Does someone knows where to look for?
Best regards,
Mark
