If you do this a lot, and you are moving a whole volume or a qtree, beg your boss to buy snapmirror. If that doesn't work, beg your sales rep for a snapmirror eval license, then after it works so awesome, beg your boss to buy it again.
ndmpcopy does work fine though, espeically when mixed with rsync to catch things up. It depends on how active the volume is, because you'll need to rsync or do NDMP incrmentals to catch it up before you switch your mount point.
If you do this a lot (I suspect a lot of people do move stuff around often for the same reaons you suggest) and you have the $$ to consider it, you should check out www.acopia.com. They have really neat magic for dynamically moving stuff around. I haven't tested acopia, but it looks really interesting.

if you have the license, snapmirror works the best for this kind of operation. :)

Hi,
I'm new to managing Filers - I hope you'll put up
with a newb question or two while I get on my feet. I've not been left entirely on my own here - but there are two unix guys here to mange a lot of servers where before there were four of us .. and the two guys who had done this job previously are the ones who left for greener pastures. So I've got a mature and reasonably stable infrastructue to work with at least.
My first task is to move a volume from a busy
filer to a non-busy filer.
- The preferred method (for our shop, I'm told)
is to use ndmpcopy
I've got shell access to both filers, they can
ping each other. I've got a desination volume created.
ndmpcopy [options] source destination
The source and destination specify a hostname (no
problem) and aboslute pathname of the directory to be used for the transfer. Does this mean the absolute pathname of the source/destination volume? Or .. something else? If the former how do I find that?
- Unless there is a better way to do this? I can
of course mount both volumes via NFS from a 3rd host and simply move then but (from what I've read) ndmpcoy is a better choice.
