rsync to mounted samba : no space left error

view story

https://bbs.archlinux.org – Hi everyone,I am trying to create backups to a samba shared folder on a Buffalo LS410D NAS using rsync (or luckybackup). rsync runs for some time and then fail with no space left (cf later for full log). I can relaunch it it will write some more files and fail again on a later file. The files in question contains japanese character (don't know if it matters) and I can copy them using cp even after rsync failed. I tried first with luckybackup which failed (same error) and then tried with rsync. the different options tested: z, --iconv UTF8 in rsync with always -arv. In my fstab I tried ioc (HowTos)
