zfs discuss - May 2007 - how to move a zfs file system between disks

Hi all,

I am trying to write a script to move disk partitions from one disk to another.
The ufs partitions are transfered using ufsdump and ufsrestore - quite easily.

My question is :
How can I do a dump and restore of a partition that contains a ZFS file system?

P.S. 
My script would have access to the disk and its partitions , but offline - when
the machine was booted from NFS.
So I need to get access to the ZFS filesystem partition name /dev/dsk/ , either
directly or by mounting the root directory and find the partition by some zfs
command (which I do not know).

Thanks !!

Does it sound possible at all ,
or cannot be done  with the current ZFS commands yet?

You can do this using zfs send and receive. See
http://blogs.sun.com/chrisg/entry/recovering_my_laptop_using_zfs for an example.
If the file system was remote then you would need to squeeze some ssh commands
into the script but the concept is the same.

Thanks
actually I already saw the script mentioned there.

Is it possible to use zfs send/receive when the disk is not mounted?
i.e. give it device name as paramter and not zfs partition names?

It is not possible to use send and receive of the pool is not imported. It is
however possible to use send and receive when the file system is not mounted.
