我已经设置了一个包含 4 个服务器的副本集。
出于测试目的,我编写了一个脚本来使用 GridFS 将我的数据库填充到大约 1.5 亿行照片。我的照片约为 15KB。(将gridfs用于小文件应该不是问题吗?!)
几个小时后,大约有 5000 万行,但我在日志中有这条消息:
replSet error RS102 too stale to catch up, at least from 192.168.0.1:27017
这是 replSet 状态:
rs.status();

该设备仍在接受数据,但是由于我的 3 台服务器“停机”,我应该如何进行修复(比删除数据和重新同步要好,这需要很长时间,但会起作用)?
尤其是: 这是因为剧本过于暴力吗?这意味着它几乎从未在生产中发生过?
