I'm not really familiar with volatility, but at a guess, I'd say that it wants you to specify a dump directory using the --dump-dir command line option.
So I'd guess you'd need to add --dump-dir /path/to/dump/dir/ or --dump-dir=/path/to/dump/dir/ to your volatility procdump command (depending on how it takes parameters to the --dump-dir option).
NOTE: /path/to/dump/dir/ should be a valid path to a directory which already exists somewhere on your machine.
Once you have specified a directory to use as the dump-dir, I guess it will use that directory to write additional files to.
