Update about corrupted databases

[Hanska]

I’m making an update about this topic I opened few weeks ago :

A node doesnt upate its db

I’m sorry, I don’t know why. Perhaps you can try an issue on Github. Nothings in logs ? Try to restart your node and test TCP connectivity. I have a 3 nodes too, I don’t have this behaviour. But I think I will add a Prometheus/Grafana about this.

At the end the explanation was the fact that a db on a node was corrupted. I’m looking for a specific indicator in order to know for sure if a db is corrupted.

I saw this api /sys/storage/raft/autopilot - HTTP API | Vault | HashiCorp Developer
But I would need some precision about certains parameters :
What does " healthy means" specifly, can this parameters used to know if a db is corrupted?
Same question with the " last_index", I checked that whenever I add a secret, the value changes for the 3 nodes and all 3 values are the same. Does a “disynchronization” of those value can be a indicator of a corrupeted db ?

Thanks in advance for your answers
