So I ran pt-table-checksum on one of our massive tables last night. (4,000 chunks of approx 94,000 rows each).
When I ran the report this morning, there was 1 chunk whose checksum didn’t match that on master.
So I ran pt-table-sync with the --replicate option and it synced the values from 5 rows within that bad chunk. Excellent!
Now, how do I tell pt-t-c to go back and re-checksum just that one chunk and update the replicate table in all slaves?
Seems to me this should be a series of flags where I specify the table and chunk # and pt-t-c goes and re-checksums it.
