What happened?

I deployed a single-node etcd in a single-node k3s, and during normal operation, I used reboot to restart the host machine. After booting up, the etcd startup reported the following error:

{"level":"warn","ts":"2024-09-03T02:25:25.911Z","caller":"etcdserver/server.go:2075","msg":"failed to publish local member to cluster through raft","local-member-id":"7e5052d402a551ba","local-member-attributes":"{Name:apisix-etcd-0 ClientURLs:[http://apisix-etcd-0.apisix-etcd-headless.pangu.svc.cluster.local:2379 http://apisix-etcd.pangu.svc.cluster.local:2379]}","request-path":"/0/members/7e5052d402a551ba/attributes","publish-timeout":"7s","error":"etcdserver: request timed out"}

The subsequent logs repeatedly print "failed to publish local member to cluster through raft". I have confirmed that the k3s DNS is functioning correctly, and the flannel network is also normal. I cleared the data in /bitnami/etcd/data within etcd, and after restarting etcd, it began to operate normally. The logs are as follows:

I would like to understand why etcd got stuck in a "failed to publish local member to cluster through raft" loop, and how deleting the data restored normal functionality.

What did you expect to happen?

etcd started normally and is providing services.

How can we reproduce it (as minimally and precisely as possible)?

It's unclear how to reproduce this issue, as in the past, I have also rebooted the host machine without encountering this problem.

Anything else we need to know?
