# VFD SWMR Utilities

To support NFS file system, this utility applies the updater files to the copy of the metadata file.

Usage: aux_process [options] <md_file> <ud_path>

Where: <md_file> is the path to the metadata file. Must be on a POSIX file system. Note that the file may not exist yet.
       <ud_path> is the path of the updater files including the directory. This will typically be in an NFS mounted file system.

Options:
    -a --skip_aux:       Exit if VDS across multiple file is being enabled (to be implented in the future).
    -c --vfd_config:     Quoted string containing the configuration string for the VFD stack to be used. Default: sec2
    -l --log_file:       Path to the log file. Default: no log file.
    -m --md_chksum_path: Path to the file containing the checksum values for testing purpose.
    -p --polls_per_tick: Number of times to poll for a new updater file per tick. Default: 10.
    -s --stats:          Display stats on exit.
    -t --tick_len:       Integer value indicating the tick length in tenths of a second.
    -v --verbose:        Write log entries to stdout.
