NFS filesystems mounted but cannot see whats there?

Randy_9 — Tue, 12 Oct 2004 15:09:42 GMT

The Linux client mounts the NFS ( from AIX , I can "cd" into the directories, verifying NFS via "df -k .". Yet an "ls" reveals nothing?
?????

maybe you're mounting with a different user id number, and you dont have permission to read.

I am mounting as root, the filesystem is exported with the "root" access permitted for the client system?

To help I need to see the /etc/exports file.

I've recently discovered the hard way that if you don't use certain parameters on the export the files are virtually invisible, even to root.

If you want to figur it out yourself, here is the doc I used.

Steven,

The exported F/S mounts correctly and is visible to a sister system. I did noticed
via "mount | grep " that there are 3
instances of it. I have the option of rebooting the system, so I am about to. The
noted doc looks very useful also. What is weird though is /proc/mounts is linked to
self/mounts which is linked to "29366" which doesn't exist. Points assigned. Thank you!

Thanks for the points.

This is getting mysterious and probably over my head.

At this point, on a fishing expedition I'd recommend the following:

Install all NFS releated patches on the system giving you trouble. If we're talking Red Hat or Fedora up2date command will do the job quite nicely.

Pay attention to the client nfs software if thats broken up into little patches.

On the console of the system go into the export directory and do a ls -la

I'm quite interested in whats going on in those directories.

You may want to run an itrc search and see if You can get Dave Olker to look at this thread. He's pretty good with NFS.

Steven,
Thanks for your support, I will query the ITRC. I will post the resolution as soon as that is possible.

The system was updated a 10 days ago, it didn't have a problem until a few days ago.
What is equally strange, is that I can NFS mount and access ( see )F/S's from one of our HP systems, but not those from the AIX system. But at the same time the another one of our Linux servers can ( same flavor ) mount and access those same F/S's from the AIX also?
