It seems the root cause is:

Failed to attach volume "pvc-64b14071-c5db-11e6-8758-06099f2a458d" on node "ip-10-66-21-87.eu-west-1.compute.internal" with: Error attaching EBS volume "vol-02ff0c2158d03e018" to instance "i-01fb7ff93bad20e38": VolumeInUse: vol-02ff0c2158d03e018 is already attached to an instance

Could you please check what happens to your EBS volume: "vol-02ff0c2158d03e018"?

btw, EBS volume requires AWS cloud provider, are you using AWS?

george-angel · 2016-12-21T09:12:18Z

Sorry, forgot to mention, I am, volume was attached (as seen by lsblk) and mounted: xvdbb 202:13568 0 400G 0 disk /var/lib/kubelet/pods/5d12738d-c6d1-11e6-8758-06099f2a458d/volumes/kubernetes.io~aws-ebs/pvc-5d05b2bc-c6d1-11e6-a4c9-0a677903e9ed (thats a different volume now, we had to recreate).

resouer · 2016-12-21T12:06:57Z

Any could you please provide related kubelet's log? Is there something suspicious?

Line 2 and 3 are the error, and I included 1,4 and 5 for context.

The default timeout of Docker operation of kubelet is 2 min, if you are not running in very high density, it should be enough.

So what's the status of this container in docker ps? Can we make sure this prometheus container can work by simple docker run?

george-angel · 2016-12-21T13:45:06Z

Output for docker ps is in the original post:

8c2ea1120e4a        prom/prometheus:v1.2.1                                                        "/bin/prometheus -sto"   10 seconds ago       Created                                             k8s_prometheus.edf8dc49_prometheus-227300114-v7z1h_system_3d09fff2-c6c7-11e6-8758-06099f2a458d_af434bd8

And I could start the container with docker run but it started up without it's data volume.

resouer · 2016-12-22T01:49:58Z

So we can make sure it is due to EBS volume.

I can see a very suspicious ERROR: VolumeInUse: vol-02ff0c2158d03e018 is already attached to an instance. Can you check if your EBS volume has already attached a different VM other than the right node?

george-angel · 2016-12-22T09:38:36Z

Sadly not, we had to recreate the the deployment and the volume, but I will check next time we run into this.

dimpavloff · 2017-03-07T16:04:35Z

Hi, we have a very similar setup as above (CoreOS , docker 1.12.6 , k8s 1.5.2, a prometheus Pod with EBS) and are seeing the same issue for the prometheus Pod and any other pods subsequently scheduled on the same node.

After a lot of digging, our hypothesis is that the prometheus process, upon starting, tries to go through all the data in the EBS volume (~24 GB for us) which causes it to max out the provisioned IOPS and thus throttle any IO on that volume. The IOPS are definitely maxed out, we've confirmed via the AWS CW metrics.
We observed a correlated extreme slowdown of docker ps (it takes 5 mins to return in our case. Calling docker ps immediately after the slow call has returned is instantaneous). OTOH, docker inspect continues to be operational throughout the slowdown period and it reports the container as actually running.

Could the kubelet be making a call which hits a code path similar to docker ps ? The worst part is that this affects the entire node whenever it happens -- any other pods that get scheduled on it, also get stuck in ContainerCreating, presumably because the docker runtime is completely unresponsive. In the many attempts for the prometheus pod to startup, it was never eventually successful apart from once. I.e. this was happening in a loop on the node, with backup period breaks in between, and whenever it was happening, it was breaking any other Pod scheduled on it.

Here are the relevant kubelet logs:

We have the same problems with a cluster on google gke, the solution i found so far is to provision again the node, but is becoming quite unacceptable as we are using the cluster to do continuos integration of several projects and there is no automation that can handle the docker failure on a node.
@dimpavloff have you found any solutions ?

guoshimin · 2017-03-23T23:49:15Z

We are also hitting this issue after upgrading to v1.5.4 from v1.4.7. We noticed that in v1.5.4, kubelet adds a :Z to each bind mount spec if SELinux is enabled on the system. We patched kubelet to disable this behavior and the problem went away.

Our running theory is that this causes libcontainer to try to recursively label all the files in the prometheus volume, which has a lot of files, and the container create request times out.

cc @pmorie, author of 21116a7. Does my theory in the comment above make sense?

The relevant docker code is

https://github.com/docker/runc/blob/54296cf40ad8143b62dbcaa1d90e520a2136ddfe/libcontainer/label/label_selinux.go#L144, and

The problem AFAIK is a more extended and includes also older Docker releases and it's not limited just to volumes, I think that the error message is quite generic to do a complete analysis. Maybe k8s should do some sanity check to Docker/containerd to understand the reliability of pods provisioning. Il giorno ven 24 mar 2017 alle 09:28 guoshimin <notifications@github.com> ha scritto:

cc @pmorie <https://github.com/pmorie>, author of 21116a7 <21116a7>. Does my theory in the comment above make sense? The relevant docker code is https://github.com/docker/docker/blob/v1.12.6/volume/volume.go#L127-L131, https://github.com/docker/runc/blob/54296cf40ad8143b62dbcaa1d90e520a2136ddfe/libcontainer/label/label_selinux.go#L144, and https://github.com/docker/runc/blob/54296cf40ad8143b62dbcaa1d90e520a2136ddfe/libcontainer/selinux/selinux.go#L481-L483 — You are receiving this because you commented.

For me restarting docker on the node is quicker that provisioning a new node @paolomainardi
I am seeing this mostly on the node running a prometheus container (kube-prometheus)

Restarting the node is not always the answert, sometimes Docker can get stucked because disk is full or broken inodes. Il giorno ven 24 mar 2017 alle 14:28 Duncan McNaught < notifications@github.com> ha scritto:
