Opendaylight - Unable to join cluster

Opendaylight bundles in GracePeriod and cluster not coming up

QUESTION

Opendaylight - Unable to join cluster

Asked 2018-Jul-10 at 17:04

We recently moved to Nitrogen-SR3 and we have customized clustering with 2 node. When we restart a node (ie., after failback), we observe following exception in karaf.log and the node is unable to join the cluster. Any help is highly appreciated.

QUESTION

Opendaylight bundles in GracePeriod and cluster not coming up

Asked 2018-Jul-06 at 07:58

We are using ODL Nitrogen version. When we perform warm start (ie., restart Karaf servers, without deleting "KARAF_HOME/data" folder following bundles are in "GracePeriod" state for a long time, hence other application bundles that are dependent on this are failing. However when we start Karaf in a clean (without data folder) state, all bundles comes up fine.

We also noticed, netty.tcp port 2550 is not getting binded when bundles goes into failure state. Confirmed this port is not being used by other process also.

You need to set SO_REUSEADDR to enable the port to be directly reused after it is closed. See https://docs.oracle.com/javase/7/docs/api/java/net/StandardSocketOptions.html#SO_REUSEADDR If you do not set this option then the port will stay blocked for a while dependent on the operation system.

You should also not forcefully kill a process if possible as this does not cleanly shut down the ports.

An excellent analysis using fuzz testing of akka-raft, discovering a number of protocol bugs by @colin-scott, blog post [Fuzzing Raft for Fun and Publication](https://colin-scott.github.io/blog/2015/10/07/fuzzing-raft-for-fun-and-profit/) and linked inside it the whitepaper draft. [Raft - In Search of an Understandable Consensus Algorithm](https://ramcloud.stanford.edu/wiki/download/attachments/11370504/raft.pdf) whitepaper. See other implementations (many lanugages) on [raftconsensus.github.io](http://raftconsensus.github.io).
