transfer data

matthew mills — Tue, 20 Jan 2004 16:16:37 GMT

I am trying to transfer a few large files from one HPUX server to another. I can not use ftp. I am using the â cp -r -p â command on a NFS mount. The error message I am getting is:
cp: cannot access /net/VA/compindex.dbf: Value too large to be stored in data type
cp: cannot /net/VA/comp_1.dbf: Value too large to be stored in data type
cp: cannot access /net/VA/comp_temp_01.dbf: Value too large to be stored in data type.

these are the file size:
3145736192 comp_1.dbf
2621448192 comp_temp_01.dbf
3145736192 compindex.dbf

Please

Hi Matthew,

Does the destination FS for these files support largefiles?

Also you want to insure that you're using NFS v3 on this mount as I seem to remember that v2 did not support files >2GB.
Run
rpcinfo on both client & server to determine NFS version running.

HTH,
Jeff

Hi,

Looks like the largefiles is not enabled on /VA filesystem on the remote server. Try enabling it.

Hi,

You will need to do it on the remote server. If you have online-jfs installed on that server, you could do

fsadm -o largefiles /mount_point

If you don't have online-jfs, then you will need to umount the filesystem and then enable largefiles. /mount_point is the mount point containing the directory that is NFS exported.

umount /mount_point
fsadm -o largefiles /dev/vgxx/lvolx

/dev/vgxx/lvolx is the logical volume containing the filesystem.

mount /mount_point
