Huge LV transfer 1

[mixmouse]

I have a huge LV,more than 130G needs to be transfered to from old disk using JFS to a new disk using JFS2. I tried to use "cp", but cp command has a buffer limited, so I can not use "cp -R *" to move files.
I think about the tape backup, but it takes too long to finish, also I don't have enough tapes to do store this huge LV. What about disk mirroring?

Is there any other ways to do this job?

Thanks.

cd /olddir
find . -print | cpio -pd /newdir

"man cpio" for details.

Thank you. This is a truly wonderful idea.

There is another way to do this, using tar, as follows:

cd /olddir
tar -cf - | ( cd /newdir ; tar -xvf - )

The first tar creates an archive stream on its stdout, and a shell reads it into the stdin of the another tar after changing working directory.

The second tar is set to verbose to see if all files are transferred in order.

tar won't work if any of the files are over 2GB in size.

Yes, you are right. AiX native tar (especially in version 4.3.3) can't handle big files over 2 Gigs. GNU tar can do it. Backup/restore commands also work.

also the pax command - as an alternative to tar
