差异和NFS卷

Question

我有一个夜间工作，运行回归测试，将结果存储到NFS安装的卷，然后对今天和昨天的结果做差异。我收到两个文件"No such file or directory"但它们存在！

diff: /mnt/remoteVol/results/Regression/NightlyRegressions/yesterdaysDate/summaries.txt: No such file or directory
16:49:47 diff: /mnt/remoteVol/results/Regression/NightlyRegressions/todaysDate/summaries.txt: No such file or directory

然而，如果我 cd到/mnt/remoteVol/results/Regression/NightlyRegressions/yesterdaysDate

然后 diff summaries.txt ../ todaysDate / summaries.txt

有效！？

路径中没有符号链接，NFS服务器上没有原始diff WORKS。

我找到了我的修复程序，但想知道为什么这不能用原始格式

提前致谢。
