Hi,
Try using the optimize table tablename ,but this will keep the data accordingly,but really
if it is a disk space constraint you can go with re-org process in which you will have to
get a down time for mysql db.Process is something like .
Dump all the Innodb tables drop the existing innodb tables and shutdown mysql, clear the
Innodb log-space as ibdata1 & indata2 & iblogfile0 & iblogfile1 and also the
redo logs of the innodb.
Then start the mysql this will create innodb logs 1 & innodb2 as what u have mentioned
in ur cnf file and import the dump .
In this case u can able to reduce the space usage of innodb.
Try this it might help u out.
With Regards
Dilipkumar
