根因分析

副本节点上配置的驱逐策略与主节点的策略不同，导致复制期间内存管理不一致。

English

The eviction policy configured on a replica node differs from the master's policy, causing inconsistent memory management during replication.

解决方案

  1. 将副本的 maxmemory-policy 与主节点对齐：在副本上运行 CONFIG SET maxmemory-policy allkeys-lru（或匹配主节点的策略）。
  2. 检查两个配置：在主节点和副本上运行 redis-cli CONFIG GET maxmemory-policy，然后永久更新副本的配置文件。

无效尝试

常见但无效的做法:

  1. Ignore the warning, assuming it's harmless 50% 失败

    Can lead to data inconsistency between master and replica, or unexpected evictions on replica.

  2. Set a different policy on the replica without matching the master 60% 失败

    Replicas must follow the master's eviction policy to maintain consistency; otherwise, replication may fail.
