Mounting a gcePersistentDisk kubernetes volume is very slow
<p>I start a kubernetes replication controller. When the corresponding container in the single pod in this replication controller has a <code>gcePersistentDisk</code> specified the pods will start very slow. After 5 minutes the pod is still in the <code>Pending</code> state.</p>

<p><code>kubectl get po</code> will tell me:</p>

<pre><code>NAME          READY     STATUS    RESTARTS   AGE
app-1-a4ni7   0/1       Pending   0          5m
</code></pre>

<p>Without the <code>gcePersistentDisk</code> the pod is <code>Running</code> in max 30 seconds.</p>

<p>(I am using a 10 GB Google Cloud Storage disk and I know that these disks have <a href="https://stackoverflow.com/q/23683271/454103">lower performance</a> for lower capacities, but I am not sure this is the issue.)</p>

<p>What could be the cause of this?</p>
