I am using pt-table-checksum between mysql5.0 master - mysql5.1 slave. Initially the configuration on the master was to replicate only one database (kdb). Then I have removed the filters (replicate\_do\_db, binlog\_do\_db) and now replication works between all the other databases. For example I create a user on master and it replicates all grants and the user to the slave. This is good so far. But when I run pt-table-checksum again on the new setup of full replication, it still only displays the old database and it doesn’t checksum other databases i.e. mysql,test etc. I only get output for one database kdb and not others. Viz: … 03-07T09:51:00 0 0 36 1 0 0.047 kdb.t1 03-07T09:51:00 0 0 7 1 0 0.034 kdb.t2 03-07T09:51:00 0 0 15 1 0 0.076 kdb.t3 … What could I be doing wrong? Many thanks. Kubilay ---

can you please show command you used for [pt-table-checksum](http://www.percona.com/doc/percona-toolkit/2.2/pt-table-checksum.html) and pt-table-checksum version too.
