@xiaods as u can see the metrics , my disk is ssd and etcd metric "etcd_disk_wal_fsync" shows ok，and this problem only occurs when an old member(its termId is greater then...

i do not think so, as the etcd log shows ，when leader changes，the master just reply slower than the worker, and the leader change has already finished
