tar command question

dictum9 — Thu, 20 Apr 2006 09:01:29 GMT

OK, I am getting confused with it, here is the situation.

I have 2 directories:

/oracle and /oracle_temp

I need to move the contents of /oracle to /oracle_temp, it's about 12GB. I just created the oracle_temp LV and mounted it.

How do I run the tar command to copy all the files? Or do I use find and cpio?

cd /oracle
tar cf - . | ( cd /oracle_temp ; tar xf - )

I suggest you to use the cpio pipe, no restrictions on file size and the right mamagement of links and permissions.

find source_dir -depth -print | cpio -pcdumv newdir

Shalom etc,

I'd use the mv or cp command

mv /oracle/* /oracle_temp

cp -R /oracle/* /oracle_temp

The database must be down if this includes database data files.

Hi,

# find /oracle | cpio -pcmudv /oracle_temp

If the lvs are on two systems scp -rp will work well.

cpio is much faster.

cd /oracle
find . â xdev â depth â print|cpio â pmd /oracle_temp

Unless you've got it backed up with Data Protector, in which case I'd use that.

OK, this one is working great, thanks to all.

# find /oracle | cpio -pcmudv /oracle_temp

Apologies for the formatting in my earlier response - that's what I get for copying from Mickeysoft T*rd! And mine was the first response when I typed it - honest! When I say that cpio is faster, I mean compared with tar rather than compared with someone else's solution. My solution again (typed rather than copied):

cd /oracle
find . -xdev -depth -print|cpio -pmd /oracle_temp

The following did not copy all the files, why is that? It left out
the 9ias director. And the space is fine.

# find /oracle | cpio -pcmudv /oracle_temp

# ll /oracle
total 6
drwxr-xr-x 7 oracle dba 1024 Jul 14 2005 9ias
drwxr-xr-x 2 root root 96 Jun 1 2005 lost+found
drwxr-xr-x 2 oracle dba 2048 Apr 18 13:12 v10

ll /oracle_temp
total 0
drwxr-xr-x 2 root root 96 Apr 20 09:52 lost+found
drwxr-xr-x 5 oracle dba 96 Apr 20 10:24 oracle

It appears to have copied everything across in a single directory called oracle. Have you looked inside this directory?

I had to remove everything and start over. This one copied all the files correctly.

find . -xdev -depth -print|cpio -pmd /oracle_temp
