I wanna know if IPFS has a mechanism to detect nodes if they fails to work. If does, how is the mechanism working?
You mean self-check? Yes a node will detect that the DHT is not reachable.
Hi, yes. Thank you. Also, do you have any idea on if there is a replication mechanism within IPFS cluster to detect node failure and failover the content to other node to maintain redundancy?
IPFS-Cluster will detect if min-redundancy for a pin isn’t met anymore and act accordingly.
This requires that min-redundancy is >= 2.
