我尝试为我刚刚移动的数据库执行mysqldbcompare，但获得Database consistency check failed.，我还做了另一个mysqldump并使用diff并显示该数据库为consistent，但我仍然想了解为什么mysqldbcompare说：Database consistency check failed.
$ mysqldbcompare --server1=XXX --server2=XXX openx:openx --run-all-tests --disable-binary-logging
# server1 on XXX: ... connected.
# server2 on XXX: ... connected.
# Checking databases openx on server1 and openx on server2
