When i try to figure out why this issue occurs, i find that the result of last raft log file is different with my guess.Here are the result of my test environment (ps.I ran into the same problem.)

We find these files of raft log:

/.../system/raftLog/-1869016501/49923372-9223372036854775807-244-idx, 
/.../system/raftLog/-1869016501/48875442-49224751-241-idx, 
/.../system/raftLog/-1869016501/49224752-49574061-242-idx, 
/.../system/raftLog/-1869016501/49574062-49923371-243-idx

/.../system/raftLog/-1869016501/49574062-49923371-243-data, 
/.../system/raftLog/-1869016501/49923372-9223372036854775807-244-data, 
/.../system/raftLog/-1869016501/48875442-49224751-241-data, 
/.../system/raftLog/-1869016501/49224752-49574061-242-data

and process these files (242-index and 243-data?) :

Obviously, we have a problem with where the files are sorted.That may be a bomb in recover module.
