Is there any problems running the pt-table-sync or pt-table-checksum on the slave and setting the DSN to the master?
In terms of the checksum. Does the percona database only get created on 1 server or is it created on the each server in the replication setup?
E.g. Our master server is running slightly tight on space until we’re able to resize the partition during our next maintenance period so would like to have the percona database on the slave only so not to use disk space on the master.
Ideally I’d also like to be able to run the pt-table-sync from the slave rather than having to install the percona tool kit on the master too.
