<p>I have a cluster on google cloud container engine with 6 <code>n1-standard-1</code> machine.</p>

<p>I deployed several services and pod on this cluster and sometime they fail with the only reason <code>FailedSync</code> and no more explanation, I have no idea why they fail. Virtual machine are not overloaded, only 6% of the CPU is used and less than 1Gi of memory.</p>

<p>Here some events from describe command :</p>

<p>pods filter by <code>is system object: true</code> have the same problem, some of them have more than 900 restarts in 4 days...</p>

<p>I miss maybe something in my kubernetes configuration and I have no idea what...</p>

<p>Thanks for your help</p>

<p>I finally found the reason of the node failures. I use a glusterfs volume with the https://eventstore.org/ database and I think the latency make it fails, I saw lot of slow queries in the eventstore logs. I don't really know what happen but since I use a persistent ssd disk in the same region of my cluster I have no issue. 0 restart since several days and nodes work like a charm.</p>

<p>I also isolated this database on a single node.</p>
