Hi Martijn,

can you make a backup of the database directory and then start with the 
following two additional options:

  --database.ignore-datafile-errors true
  --wal.ignore-logfile-errors true

This will ignore any errors found due to the disk space shortage. If 
ArangoDB has been started, shutdown again and try without these options. 
Does this solve the problem?

Best
  Frank
