NAME
nfstest_io - I/O tool
SYNOPSIS
nfstest_io -d <datadir> [options]
DESCRIPTION
This I/O tool is used to create and manipulate files of different types. The arguments allow running for a specified period of time as well as running multiple processes. Each process modifies a single file at a time and the file name space is different for each process so there are no collisions between two different processes modifying the same file.

show this help message and exit
-d DATADIR, --datadir=DATADIR
Top level directory where files will be created, it will be created if it does not exist
-s SEED, --seed=SEED
Seed to initialized the random number generator [default: automatically generated]
-n NPROCS, --nprocs=NPROCS
Number of processes to use [default: 1]
-r RUNTIME, --runtime=RUNTIME
Run time [default: ’0’]
-v VERBOSE, --verbose=VERBOSE
