copying more than 2GB(disk to disk)

[mehul_3]

Hi there!
I am going to implement a hot backup(oracle9i Database)on hp-ux11i server.
I was getting stuck when I copied a file from disk to disk which is greater than 2GB and an individual datafile size is of appr. 25GB.
Is there any way/solution to copy an individual file more than 2GB.
I can use fbackup to copy directly to tape but could not be appended the contents to previous backup.

Any help is greately appreciated.

Mehul,

Check out whether your destination Filesystem allows files bigger than 2Gig. File /etc/fstab has option as largefiles.
If not you will not be able to copy your Files bigger than 2 Gig.

following is the entry in /etc/fstab
/dev/vg01/lvol10 /opt/install vxfs rw,suid,largefiles,delaylog,datainlog 0 2

more over when you create a new filesystem during creation you should mention

#newfs -F vxfs -o largefiles /dev//rlvol1

then mount it with the above given options in /etc/fstab.

cp -rp will help you the best.

Hi,

It seems that largefiles options is not set on the file system where you are copying your files. Check /etc/fstab for the option as mentioned earlier. Also if not set you can set this option online using

#fsadm -F vxfs -o largefiles /dev/vgxx/lvolyy

you could always use the dd command.

#dd if= of=

enjoy!

I do agree with the dd command but I would like to copy entire directory structure with subdirectory and files into which it resides
e.g say I wants to copy /u01/gdbs/datafiles to /u05/hotbackup

Any idea!

Mehul,

We have been doing it on our servers using cp -rp . Full filesystem move. Please confirm whether your dest. Filesystem allows files bigger that 2GB. Check in fstab and characteristics given by Devender
