If there is a network partition for a long period of time can serf automatically recover? To define some terms:
long - longer than suspicion timeouts (ie all nodes across the partition are confirmed dead)
recover - combine the resulting two clusters into a single cluster
For example, there are four nodes A, B, C, and D. A network partition causes A and B to be isolated into their own cluster, and C and D are isolated into a separate cluster. Now the network is fixed. Will the two split clusters be able to recover and form a single cluster with all four nodes?
One could manually heal the split by adding a node with peers from both clusters.
Thanks for the awesome project!
The text was updated successfully, but these errors were encountered:
"Suspicion" timeouts will turn into death("Dead") events, which the node in question could revoke it turning intself "Alive" again.
NetPartition will make this impossible, so the node is marked as dead.
after the serf node is marked as dead the member will be only keep around until the member list is cleaned up, which will remove dead nodes then. after that a manuel rejoining is required to reconnect the "Cluster" back together.
