Hello, could you please help me? I have Percona Server 5.7 and latest Percona Toolkit installed.
I want to run pt-online-schema-change to get some diskspace
As per information schema I have a lot space to reclaim. Also, checking table status, I found that many tables consuming 2 GB when on OS side it occuppies 1.5 GB (this is an example)
After pt-online-schema-change run I see that table status shows increased table size as well as from OS side
Whats wrong? What additional information should I add?
Thanks in adnvace
