【 TiDB 版本】v4.0.9
【遇到的问题】
我从生产环境full备份的db 文件夹，拿到测试环境做restore 失败，（测试环境 是单点的），是不能这样使用吗？
./bin/br restore full --pd 127.0.0.1:2379 --storage “/root/full-2022-06-21” --ratelimit 128 --log-file restore_db.log
Detail BR log in restore_db.log
Full restore <-------------------------------------------------------------------------------------------------------------------------------------------------------> 100.00%
Error: rpc error: code = Unknown desc = rpc error: code = Unavailable desc = not leader
以下是 restore_db.log，报错非常多，我截取一部分如下：
