Hello,

I am moving 20 GB of data from a 220 to a 330. A support engineer at Network Appliance suggested using ndmpcopy. I acquired this software and compiled it on a Solaris 2.5.1 machine and am now testing.

I have a 190 MB directory that I copied from the 220 to the 330 in 9 minutes using GNU tar over the public 10mbs network.

I then tried to copy the same data using ndmpcopy. It took 1 hour 6 minutes! I set up a direct ethernet connection between the two filers running at 100mbs full duplex.

From a Solaris 2.6 workstation on the public network I kicked off the ndmpcopy. nac220 is the 220, nac330 is the 330 and nac330-bak is the private 100mb network connection between the two.

Here is my command:

ndmpcopy nac220:/vol/vol0/testdir nac330:/vol/vol0/testdir -sa root:pass -da root:pass -d nac330-bak

One other piece of info--the 220 is used to store Netnews data. When I am testing I have not turned news off, so the data is continually changing. When I do the actual transfer news will be turned off. But I can't turn it off for my testing.

1. Is my ndmpcopy command correct?

2. Is it abysmally slow because the news is still up?

Thanks for any help.
