cp problem

Achilles_2 — Mon, 09 Jul 2007 22:58:20 GMT

Hello there,

I face a problem if the file size is too large, e.g, 3Gig, I can't use rcp, cp and mv command because it returns the error:
cp: xxx.tar: File too large

So do any expert have any suggestion to copy such kinds of file?

Thanks

To what are you trying to copy it? (To a
file system which doesn't support large
(>2GB) files?)

Why not show the actual commands and their
actual output?

Display the options setup for your destination filesystem:

fsadm /dev/vg00/rlvol1

or whatever filesystem you are using. You will see something like this:

fsadm /dev/vg00/rlvol1
file system : /dev/vg00/rlvol1
magic number : 95014
feature bits : 1
file system supports : nolargefiles, longfilenames

In this example, lvol1 does *NOT* allow any files larger than 2Gb. Use fsadm to change the capabilities of a filesystem (man fsadm_vxfs)

eg.

mkfs -F vxfs -o largefiles /

Oops should be fsadm not mkfs

Yes, the destination that you are copying the file too must be enable with large files.

For example you trying to move file to /misc(the lvol1 is mounted to /misc):
Check if it is largefilesystem
#fsadm -F vxfs /dev/vg01/rlvol1
nolargefiles

To Enable Largefilesystem
#umount /misc
#fsadm -F vxfs -o largefiles /dev/vg01/rlvol1
#fsadm -F vxfs /dev/vg01/rlvol1
largefiles

To Disable Largefilesystem
#umount /misc
#fsadm -F vxfs -o nolargefiles /dev/vg01/rlvol1
#fsadm -F vxfs /dev/vg01/rlvol1
nolargefiles
