can't get cluster going: etcdserver: publish error: etcdserver: request timed out

[miekg]

I'm trying to start a cluster with:

./etcd -name pi0 -initial-advertise-peer-urls http://10.248.0.1:2380 -listen-peer-urls \
http://localhost:2380,http://localhost:7001,http://10.248.0.1:2380 -listen-client-urls \
http://localhost:2379,http://localhost:4001,http://192.168.1.10:4001 -advertise-client-urls \
http://localhost:2379,http://localhost:4001,http://10.248.0.1:4001 \
-initial-cluster-token pi-etcd \
-initial-cluster pi0=http://10.248.0.1:2380,pi1=http://10.248.0.2:2380,pi2=http://10.248.0.3:2380\
 -initial-cluster-state new

But this keeps failing with:

2015/02/14 12:23:39 etcdserver: publish error: etcdserver: request timed out

I've seen issue #/2276, but this seems again different. I am also not able to capture any network traffic and any interface. So that explain it's timing out, but not sure where to go from here...

@miekg Can you provide more logs of the 3 members you started?

[miekg]

There all identical, but I'll attach them here.

[xiang90]

@miekg This is wired... I think these are the arm machines restarted from unexpected failures.

[miekg]

@xiang90 sorry I don't get your comment? The machines are running fine and use a wired 10-network to talk to each other (they also have a wireless interface)

[xiang90]

@miekg I mean are there etcds the ones on the pi machine? From the log, I see they have failed before.

[miekg]

That failure would probably be #2308 .

[xiang90]

@miekg Right... So your cluster actually has not setup properly. We need to solve #2308 first.

[miekg]

Ack. I want etcd on my arm cluster, so I will poke/fix/tweak until it works.

[xiang90]

@miekg I am closing this since the root cause is #2308.

I'm experiencing the same issue trying to add a node to an existing cluster.

I run etcdctl member add, get the env vars, and run this on the CoreOS box of the new node:

rm -rf /opt/etcd/*
/usr/bin/docker run   --net=host   -t -i --rm   -p 2379:2379   -p 2380:2380   -p 4001:4001   -p 7001:7001   -v /opt/etcd:/opt/etcd   -v /usr/share/ca-certificates/:/etc/ssl/certs   quay.io/coreos/etcd:v2.0.8   --data-dir /opt/etcd   --name hivemind-04.${COREOS_PRIVATE_IPV4}     --listen-client-urls http://0.0.0.0:2379,http://0.0.0.0:4001   --advertise-client-urls=http://${COREOS_PRIVATE_IPV4}:2379,http://${COREOS_PRIVATE_IPV4}:4001 --listen-peer-urls=http://${COREOS_PRIVATE_IPV4}:2380 --initial-advertise-peer-urls=http://${COREOS_PRIVATE_IPV4}:2380 --initial-cluster=$ETCD_INITIAL_CLUSTER --initial-cluster-state=$ETCD_INITIAL_CLUSTER_STATE

Initially, everything seems fine, but eventually this starts happening:
