ZFS通过为写入的每个块的元数据生成32位校验和(或256位散列)解决了此问题。
ZFS solves this issue by generating a 32-bit checksum (or 256-bit hash) for metadata for each block written.
你可能还有两个客户端校验来确保用户名和密码不要少于一位字符或太长,或者不包含任何无效字符。
You might also have two client-side validators that ensure that the username and password are at least a character or so long, or perhaps don't contain any invalid characters.
