Hi,
The comment is just telling you how much free space is in your InnoDB
datafile(s). When that approaches 0, InnoDB will add the data file.
Image that there's a box, say it Innodb tablespace, this box is consist of
your data,
and innodb free is the same as the (capacity of your box - usage)
To increase the size simply add innodb data file.
MySQL documentation: The data files (tables) that you define in an InnoDB
form the tablespace of InnoDB. The tablespace consists of database pages
with a default size of 16KB. The pages are grouped into extents of 64
consecutive pages (i.e. 1024Kb). InnoDB allocates space starting from the
first data file (table). InnoDB can add a large segment up to 4 extents at
a time to ensure good sequentiality of data (4096Kb).
Thanks,
