Hi,

This means that that particular userid does not have permission to read the contents of that directory.

as root
ls -la in the directory.

There is probably some wierd permission thing going on.

To change dir you need execute permission.
Read is possibly off.

A strange exmaple of permissions.
create a dir with write perms.
make the files in that dir read only.
rm the files from the dir.

The dir contains the files index. the index can be removed from the dir.

rm the files from the dir as any user btw.

All of non-user root have the right permission.
especially the owner of the directory has the same problem.

hi,

"ls -A" shows all files, except "." and ".."

"ls -a" shows all files, including "." and ".."

probably nothing new to you, but anyway ;-)

Thierry.

Hi,

Do you see '.'? Or any other .* file? Maybe 'ls' is aliased to 'ls -A' which is default (see the man page, focus on -A).

Whith the user root, I put all the permission on the ".." files..

how's the filesystem mounted?

type mount -p

Is it nfs exported/mounted?

hi bill,

here is the output of mount -p
dev/vg01/lvol2 /DA/SAS/prod vxfs delaylog,nodatainlog 0 0

It's not a nfs file system..

The inode table in sar will always look full shortly after a reboot. This table is a cache of current and recently opened files. Unfortunately, the kernel does not provide a simple way to determine reusable entries, thus the sar metric shows all inodes including files that were recently closed.

As mentioned, the ability to 'see' directories and files using ls/ll is solely dependent on the permissions of the parent directory. If you create a directory with 700 permissions, any attempt to use ls/ll on the directory will report: "unredable" for all but the owner.

And if you try to cd into the directory, you will get "Permission denied".
