Node 'riak@192.168.1.218' not responding to pings

问题

I have no idea what happend with the system, but suddenly when I issue riak start it doesn't start anymore. I get this output.

And if I issue riak console, I get no response for pings. I don't know what to do, so please advise how to put the system back online.

So the whole process here is that

• for some reason IP was changed on the machine riak
• the IP was hard-coded in /etc/riak/vm.args and /etc/riak/app.config

the process to revive is the following:

• edit and set the new IPs in the above files
• sudo rm -rf /var/lib/riak/ring/* # delete the riak ring
• restart the machine or do the next steps:
• riak-admin cluster force-replace riak@127.0.0.1 riak@"hostname -i" # replace the name
• riak start # start the node

This topic is also linked to this problem: Riak node no longer working after changing IP address

A simple way to initiate a new riak node is simply run riak console on your riak container bash.

1. If riak is a container in your docker then follow this procedure (MAC)
a. get riak image id <docker ps --all>
b. run bash command <docker exec -it "riak-container-id" bash>
c. run <riak console> this initiates a new riak node console
d. open another terminal and run <riak-shell>
e. run command<connect use your node created at step c> it will look like 
riak@10.1.0.216

there you go.
