Hello,
@Tycho: I'm so sorry, i can't find the right option to send my reply
correctly to the list.

*1)*
I try to increase data size in the container like that:

           root at worker:/home# vim MyTestFile.txt
           root at worker:/home# du -sh MyTestFile.txt
           4.0K    MyTestFile.txt
           root at worker:/home# truncate -s 16M MyTestFile.txt
           root at worker:/home# du --apparent-size -h MyTestFile.txt
          16M    MyTestFile.txt

Then Dumping Process: in ImGLXC1Worker directory

           root at g-3:/home/ImGLXC1Worker# du -sh
           *7.9M   * .
           root at g-3:/home/ImGLXC1Worker# du -h
          7.9M    .


*2)*  i have increased the size from *16M to 160M*

          root at worker:/home# truncate -s *160M* MyTestFile.txt
          root at worker:/home# du --apparent-size -h MyTestFile.txt
          160M    MyTestFile.txt

     Then Dumping Process: in a new ImGLXC1Worker2 directory
          root at griffon-38:/home/ImGLXC1Worker2# du -sh
          *7.7M *

Have you an explanation please ?

Thanks a lot for help.
Best regards.
