Shalom,

You can safely delete them

I would use a find +mtime

It is always good to keep your system fully patched with the latest stable NFS patches.

This may be a client issue though.

These occur when NFS files are removed and a process still has the file open.

>SEP: I would use a find +mtime

That's: find -mtime +nnn

Thank you for your reply

But, i want to kwon what is those files.
Did files made by server processor or
client?.

>I want to know what is those files.

Files that have been removed but were busy.

>Did files made by server or client?

Most likely by the server but it could be symmetric.

Re: many .nfsXXXX files in several directories

Thanks a lot.

I tried about the file occured as below:
1. A file create on the nfs client.
2. open the file with vi.
3. remove the file from nfs server.
4. the file close on the nfs client.
5. i find .nfsXXXX file
but, I don't found .nfsXXX file

is there problem my test schenario?

Re: many .nfsXXXX files in several directories

>2. open the file with vi.

This opens the file, reads it and then closes it.

>is there problem my test scenario?

Yes, you must leave the file open, try using "tail -f" on the file.

Re: many .nfsXXXX files in several directories

Hi,

I've had such files at my filesystem several times.
They were created at the server while running an application at a client, then trying to delete a file unsed by the application.
Normally, I believe, the .nfsxxx files should be deleted when the server (or the application at the client) doesn't need the file anymore.
Maybe this occures if you use hpux applications like 'vi' (and close vi), but it doesn't happen sometimes with foreign apps.
