当尝试在OpenShift中执行Build时，它立即失败并显示错误 ＆＃34;由于缺少磁盘空间而无法启动＆＃34; 在事件查看器中。
我似乎无法弄清楚为什么OpenShift认为当一切看起来都不错时我在磁盘上处于低位。以下是服务器上的一些细节。

已编辑添加以下其他详细信息。
仍有问题。它看起来可能实际上在Kubernetes中存在问题，但我不确定。
我根据Kubernetes用于确定是否有足够的磁盘空间来运行以下GO程序。
package main
import (
"fmt"
"os"
"syscall"
)
func main() {
pathArg := os.Args[1]
stat := syscall.Statfs_t{}
err := syscall.Statfs(pathArg, &stat)
if err != nil {
fmt.Println(err.Error())
return
}
//bsize := stat.Bsize
//fmt.Println(stat)
s := fmt.Sprintf(`
Statfs_t {
Type %d
Bsize %d
Blocks %d
Bfree %d
Bavail %d
Files %d
Ffree %d
Frsize %d
Flags %d
}
`, stat.Type,
stat.Bsize,
stat.Blocks,
stat.Bfree,
stat.Bavail,
stat.Files,
stat.Ffree,
stat.Frsize,
stat.Flags)
fmt.Println(s)
}
然后我通过以下
运行它for x in $(sudo df -h | grep -v Filesys| awk '{print $6}'); do echo "Running on $x"; sudo ./fsinfo $x; done;
并收到了以下结果，这些结果似乎也没有显示任何磁盘空间问题。
我想知道我是否应该将此作为错误报告提交给Kubernetes？
