$ influx_tsm -h
:<<DOC
Usage: influx_tsm [options] <data-path> 
Convert a database from b1 or bz1 format to tsm1 format.
This tool will backup the directories before conversion (if not disabled).
The backed-up files must be removed manually, generally after starting up the
node again to make sure all of data has been converted correctly.
To restore a backup:
  Shut down the node, remove the converted directory, and
  copy the backed-up directory to the original location.
Options:
  -backup="": The location to backup up the current databases. Must not be within the data directory.
  -dbs="": Comma-delimited list of databases to convert. Default is to convert all databases.
  -debug="": If set, http debugging endpoints will be enabled on the given address
  -interval=5s: How often status updates are printed.
  -nobackup=false: Disable database backups. Not recommended.
  -parallel=false: Perform parallel conversion. (up to GOMAXPROCS shards at once)
  -profile="": CPU Profile location
  -sz=2147483648: Maximum size of individual TSM files.
  -y=false: Don't ask, just convert
