我的OpenEBS卷被逐出。进一步分析，我发现以下状态：
$ ko get po --all-namespaces -o json | jq '.items[] | select(.status.reason!=null) | select(.status.reason | contains("Evicted")) | "\(.metadata.name): \(.status.message)"'
"monitoring-data-elasticsearch-master-0-4102165699-target-55n979: Pod The node was low on resource: [DiskPressure]. "

根本原因如下：
该节点的资源不足：临时存储。容器cstor-volume-mgmt使用的是44Ki，超出了其0的请求。容器cstor-istgt使用的是28804832Ki，超出了其0的请求。容器maya-volume-exporter使用了33064Ki，超出了其0的请求。 / p>
似乎我的POD逐渐被微量资源驱逐，例如28804832Ki〜27 Gi。
如何在OpenEBS卷上设置临时存储请求？
