Description
Hello mpifileutils developpers,
When tar'ing very big directories, tar files may exceed system accepted size for a file (typically 500 GB).
This is why one can tar and pipe with split such as
tar --verbose --create dir | split -d -b 512000m - fictar
I tried dtar, which is remarkable already on my PC, but I failed to do the same thing.
I could only write one file
mpirun -np 8 dtar --create --file fictar.tar dir
BTW the --verbose option had to be removed which contradicts the man.
Do you think my request is reasonable ? Does it make sense ?
Thanks a lot.

Research direction
No source file or test is named. Start by reviewing dtar's --create and --file handling and the documented --verbose option, then compare the requested behavior with the tar | split -d -b pipeline. Define the output-file interface and size semantics before implementation; done means dtar can produce and document multiple files for one archive.
