samba - Nov 2016 - Disk size on share with multiple partitions

Hi list,

I am exporting share which has a small base partition into which several 
much larger partitions are mounted. Which are used by different user groups.

My problem is, that windows takes the size of the base partition to be 
the size of the whole share.

If I try to copy anything larger than the base partion into a partition 
that is actually larger Windows reports insuffient disk size for the 
copy operation and quits. I can copy when I use chunks under the size of 
the base partition.

Is there any possibiity to overcome that problem, or do I have to make 1 
large partion and use quotas.

Regards, Jochen

Use the "dfree command" and "dfree cache time" to accumulate
the
space.

Thanks for the fast reply Volker,

I tried using this, but get following Errors:

../source3/lib/system.c:1143(sys_popen) sys_popen: ERROR executing 
command '/usr/bin/dfree .': Fehler im Format der Programmdatei (Error in
format of program file)
../source3/smbd/dfree.c:117(sys_disk_free) disk_free: file_lines_load() 
failed for command '/usr/bin/dfree .'. Error was : Keine Kind-Prozesse 
(no child processes)

This is on Ubuntu 16.04 using Sernet Samba 4.4.7-SerNet-Ubuntu-20.xenial

I get this no matter what I put into the shell script. I even tried 
putting: echo number number into the file

Any ideas?
Jochen
