How to Use (In standalone mode)

Once compiled, iofs can be executed via

iofs <absolute_path_target> <absolute_path_source>

Example: If you have your real data on /data/my-data, and want to measue it by accessing /opt/iofs-data, you'd use

iofs /opt/iofs-data /data/my-data

Further Configuration

All possible configuration settings can be seen via iofs --help or in the example configuration.

Everything except the mount points can be both configured via CLI parameters or config file. Note that the CLI parameters have a higher precedence.

There are 2 ways to use a configuration file:

1. Define the configuration file path at compile time.
2. Set the IOFS_CONFIG_PATH environment variable to the proper path, i.e.

IOFS_CONFIG_PATH=/home/user/example.conf iofs /opt/iofs-data /data/my-data

See here for a documented example.
