postgres : no space is left on disk

Hello, I am trying to install OSM on a virtual machine of Esxi server 6.7 whcih on debian system.

The allocated resources to the debian system are:

• ram: 30G
• disk space: 70G
• CPU: 1

I am trying to import the osm map data for Germany to postgres database.

I did this command :

postgres@osm:~$ osm2pgsql --slim -d gis --hstore --multi-geometry --number-proce                                                                             sses 1 --tag-transform-script /home/osm/openstreetmap-carto/openstreetmap-carto.                                                                             lua --style /home/osm/openstreetmap-carto/openstreetmap-carto.style -C 16500 /ho                                                                             me/osm/germany-latest.osm.pbf

Then I received this error

Reading in file: /home/osm/germany-latest.osm.pbf
