copying files larger than 2GB to nfs mount file system

[itai weisman]

hi everyone,
does anyone know how can copy files that are larger than 2GB to a nfs mounted file system?
both machines (exporting machine and mount nfs machine) runs HPUX 11.11.
thanks ppl

Hi,

What is the problem you are facing in doing so ? The only worry that should bother this should be that your file system should have large file options enabled on the original host whcih is exporting this. Check for this and report any errors encountered.

To check large file options

#fsadm -F vxfs /mount_point

HTH,

In addition, to enable it use:

fsadm -o largefiles /my/filesystem

i have exported a file system, that is formatted for largefiles (i'm able to put 2gb+ files on it locally, or put it with rcp from remote machines) but if i mount it from another machine (using nfs) - i can't put large files in it. (it sais - 'file too big' ) as cp output. (i used vxdump and tar as well in order to check where the problem is, it happens no matter how i try to put the file). i'm pretty sure the key to the solution to this problem will be on the nfs server side - since i managed to put files on a Celerra based nfs export, the was mounted the same way as the problematic machine.
i use NFS ver 3.
I also tried to put files from non HP machine (Solaris 9) - and it wouldn't work either.
i couldn't find any special option on man pages for 'exportfs' command..
any ideas?

I'm not sure about cp, but I'm pretty sure that "tar" don't support large files, "gtar" must be used.

Did you "exportfs" the filesystem, before or after you enabled the largefiles support?

Also, I found Bill Hassel's reply about similar issue, that there are some patches to be installed so NFS ver 3 will support largefiles. Is your system up to date?


Sorry for the mess, but I'm "shooting in the dark". Maybe something will hit ...
