Hi,

Just an idea, but I think that you can use
remote copy :
cd /fs1
rcp -r * hp2:/fs2

Also, you can try something like

cd /fs1
tar cvf - . | remsh hp2 -l root "cd /fs2 ; tar xvf -"
(you need a .rhost)

i'd do like the following:

cd /fs1 on machine hp1
tar cf . | remsh hp2 "cd /fs2 && tar xf -"

On hp2 in your $HOME/.rhosts insert:
hp1 your-account

Herv?s suggestion will work, your example wont.
rcp will work once the .rhosts is configured and the hostname can be looked up.

Hi
I will say use rdist command. It will keeps all your permissions and ownership unchanged.

# RDist File
# Run as:
# rdist -f filename
#
# To test RDist file:
# rdist -n -f filename
#
# To run on selected hosts:
# rdist -f filename -m host1 -m host2 ....
#
HOSTS = (
remotehost
)

FILES = (
/fs2
)

${FILES} -> ${HOSTS}
install -i -h -R /fs2;

Hi

U have got a number of solution. OK, Good. But I am asking that why don't U try through NFS. I will list out the procedure.

U have HP1 system with fs1 file system and HP2 server with fs2 file system.

U want to transfer fs1 data of HP1 to fs2 of HP2.

First in HP1.

IF NFS server service is not running
#cd /etc
#cd rc.config.d
#vi nfsconf

Change the value of NFS-SERVER variable to 1

make sure that both machines are pinging each other by using host name. If not do changes in /etc/hosts file.

#cd /sbin/init.d
#./nfs.server start
#exportfs -o root=HP2 -i /fs1 (see man page of exportfs)
#exportfs (now it should show /fs1 in list)

Now go to HP2

Check up nfsclient service is running or not.
If not
#cd /etc/rc.config.d
#nfsconf

Change the value NFS_CLIENT variable to 1

#cd /sbin/init.d
#nfs.client start
#cd /
#mkdir /HP1fs1
#mount hp1:/fs1 /HP1fs1
#cd HP1fs1
#find . -xdev -depth -print | cpio -pxdm /fs2

U can use cp -r command also, as ur wish.

Best of luck

Hi nitin,

consider S1 and S2 (server one and two ) and you want to copy the entire file system /fs1 from S1 to S2, do the following :

1. Login into S2 server.
2. Edit the $HOME/.rhosts and put in it a line like the following for example:

S1 root

3. This allow root user to execute remote commands from server S1 on server S2.

4. Log to S1 and execute on server S1 the following command :

rcp -rp /fs1 S2:/

this will create directory /fs1 (and all its subdirectories) on S2 with the same ownership, last modification date and time.

Hi,
If you r using rcp -pr or find to copy you should check the .* files are copied to the destination. I have encountered the problem with both rcp and find while x'fering files within system and to remote system.

Goodluck.
