Hey all,

I’m able to use pt-online-schema-change in order to bring an InnoDB table’s size from 6gb to 3gb without a problem. However, the disk space reported using something like df -h shows otherwise – it sometimes goes up! Even though the table size has been reduced in MySQL.

Any thoughts?

Thanks!

Hello,

It is hard to answer without having more information.  
Are you deleting the old table? The output of a df -h shows you have less free disk space? in which directory/ies?

Regards
