排查思路
根据具体事件信息确定具体问题原因，如表1所示。
事件信息 |
问题原因与解决方案 |
|---|---|
no nodes available to schedule pods. |
集群中没有可用的节点。 排查项一：集群内是否无可用节点 |
0/2 nodes are available: 2 Insufficient cpu. 0/2 nodes are available: 2 Insufficient memory. |
节点资源（CPU、内存）不足。 排查项二：节点资源（CPU、内存等）是否充足 |
0/2 nodes are available: 1 node(s) didn't match node selector, 1 node(s) didn't match pod affinity rules, 1 node(s) didn't match pod affinity/anti-affinity. |
节点与Pod亲和性配置互斥，没有满足Pod要求的节点。 排查项三：检查工作负载的亲和性配置 |
0/2 nodes are available: 2 node(s) had volume node affinity conflict. |
Pod挂载云硬盘存储卷与节点不在同一个可用区。 排查项四：挂载的存储卷与节点是否处于同一可用区 |
0/1 nodes are available: 1 node(s) had taints that the pod didn't tolerate. |
节点存在污点Tanits，而Pod不能容忍这些污点，所以不可调度。 排查项五：检查Pod污点容忍情况 |
0/7 nodes are available: 7 Insufficient ephemeral-storage. |
节点临时存储不足。 排查项六：检查临时卷使用量 |
0/1 nodes are available: 1 everest driver not found at node |
节点上everest-csi-driver不在running状态。 排查项七：检查everest插件是否工作正常 |
Failed to create pod sandbox: ... Create more free space in thin pool or use dm.min_free_space option to change behavior |
节点thinpool空间不足。 排查项八：检查节点thinpool空间是否充足 |
0/1 nodes are available: 1 Too many pods. |
该节点调度的Pod超出上限。 检查项九：检查节点上调度的Pod是否过多 |
