zfs discuss - Sep 2006 - is there any way to merge pools and zfs file systems together?

Weird question but I have two separate pools and I have zfs file system on both 
of them, I wanted to see if there is a way to merge them together?!? or I have 
to dump content to tape (or some other location) then destroy both pools make 
one big pool of those two and then create zfs on it and recover data?!?

thanks for help or any info.

Chris

Chris,

You could use ''zfs send/recv'' to migrate one of the
filesystems to pool
you want to keep. You will need to make sure that the properties for 
that filesystem are correct after migrating it over. Then you can 
destroy the pool you just migrated off of and add those disks to the 
pool you migrated to. This will prevent you from having to destroy all 
and restore.

Thanks,
George

great, yeah thats an option but I dont have anough space so I will have to copy 
those files off the system I guess and then do it, or at least from one pool 
from what I can see and then add another drive to my pool... that will work 
slightly faster :)

thanks.
