kubernetes - 访问 nfs 共享时，openshift pod 终端上的文件句柄过时

Question

我在 openshift 上有一个 spring boot 应用程序，该应用程序需要连接到 nfs 共享以创建文件。但是，每当我尝试从 pod 终端访问挂载点时，都会被拒绝。这些 ？？？如下所示

sh-4.2$ ls -la /nfs/abc/
ls: cannot open directory /nfs/abc/: Stale file handle
sh-4.2$ ls -la /nfs/abc/ (after few seconds on the same pod terminal)
ls: cannot access /nfs/abc/: Permission denied


sh-4.2$ cd /nfs/
sh-4.2$ ls -la (The first command I tried immediately after pod creation.)
total 8
drwxr-xr-x.  1 root  root    29 Nov 29 08:20 .
drwxr-xr-x.  1 root  root    50 Nov 30 08:19 ..
drwxrwx---. 14 technical technical 8192 Nov 28 19:06 abc
sh-4.2$ ls -la(few seconds later on the same pod terminal)
ls: cannot access abc: Permission denied
total 0
drwxr-xr-x. 1 root root 29 Nov 29 08:20 .
drwxr-xr-x. 1 root root 50 Nov 30 08:19 ..
d?????????? ? ?    ?     ?            ? abc

知道为什么会出现这些问号吗？
