02-16T10:22:38 Skipping table xoxdb.tb_valuelog because on the master it would be checksummed in one chunk but on these replicas it has too many rows:
149071 rows on boshiwan-hhjj-db-slave1.xox.com
148468 rows on login-server
The current chunk size limit is 132858 rows (chunk size=66429 * chunk size limit=2.0).
故障描述：用pt_table_checksum对xoxdb.tb_valuelog做同步检查， master it would be checksummed in one chunk ，也就是只能checksum1个chunk
