[CentOS] LS command bizzare behavior

Hi,

My bosses are running into an issue, where we type "ls" on a nfs mounted filesystem, and files that are there are not listed... I thought it was pilot error until my big boss showed me...

but we can vi the files, we can access them via other means if we know the name. Then once we have accessed them, LS now shows the files.

We are running centos 6.5, we are accessing them via xwin-32 (which should not be the issue)....

I looked on google and found nothing discussing this...of course this has nothing to do with hidden files (dot in front) because once we access the files we can see them.

Thanks Dan
