I also create an issue on Nvidia develop forum: https://devtalk.nvidia.com/default/topic/1023105/general/nvidia-smi-and-dev-nvidia-does-not-match/

[pineking]

这是其中一个卡在运行时丢了，dmesg 应该能看到一些信息

现在 kubelet 检测 GPU 数目比较裸，直接匹配 /dev/nvidia[0-9]+ 的数目,根据运行状态检测 GPU 数目，要等到 v1.8 或者 v1.9

多谢 @pineking dmesg 里确实有初始化失败的日志：

[1903878.128627] NVRM: RmInitAdapter failed! (0x26:0xffff:1096)
[1903878.128678] NVRM: rm_init_adapter failed for device bearing minor number 6

你们有遇到过类似问题么？

[pineking]

之前碰到过，重启解决，最近没出现丢卡情况
没继续找根源。。。
