Detailed Description

pool node. Data structure representing a node in a pool.

Pool node and pool server are two different views of the same physical entity. A pool node is how a server looks "externally" to other nodes. "struct poolnode" represents a particular server on other servers. E.g., when a new server is added to the pool, "struct poolnode" is created on every server in the pool. "struct poolserver", on the other hand, represents a server state machine locally on the server where it runs.
