[ERROR] raft: failed to take snapshot: error="nothing new to snapshot"

[ifoxhz]

I used docker run 3 nodes of raft. I stop all nodes , and restart. The all raft nodes output the error logs:

2025-03-19T17:37:45.335+0800 [ERROR] raft: failed to take snapshot: error="nothing new to snapshot"

Is there normal behavior？

I printf raft object of node:
