一个从属节点报告：
redis-cli -p 7001 info memory | grep used_memory
used_memory:10741368904
used_memory_human:10.00G
无键：
redis-cli -p 7001 info Keyspace
# Keyspace
它的主人报告了正确的尺寸：
# Memory
used_memory:4963584
used_memory_human:4.73M
持久性文件在每个服务器上的大小都相同：
-rw-r--r-- 1 root root 178 Feb 28 17:43 /var/lib/redis/dump_7001.rdb
采取的措施：在从站上，.rdb文件已删除并重新启动。从站同步成功，但仍报告差异。进行了故障转移，但没有解决。
