I think this is probably something like what I want, the problem is I'm not really "getting it" yet. If you could explain just what is happening here in an example. Let's say I have this setup; oldpool = 10 x 500GB volumes, with two mounted filesystems; fs1 and fs2 I create newpool = 12 x 1TB volumes using new storage hardware. newpool thus has a lot more capacity than oldpool, but not the same number of physical volumes or the same size volumes. I want to replicate oldpool and thus oldpool/fs1 and oldpool/fs2 on newpool/fs1 and newpool/fs2. And I want to do this in a way that allows me to "switch over" from oldpool to newpool on a day that is scheduled with the customers and then take oldpool away. So on Monday I take a snapshot of oldpool, like you say; zfs snapshot -r oldp...@sendit And I send/recv it to newpool; zfs send -R oldp...@sendit | zfs recv -vFd newpool At this point does all of that data, say 3TB or so, start copying over to the newpool? How do I monitor the progress of the transfer? Once that initial copy is done, on say Wednesday, how do I then do a final "sync" from oldpool to newpool to pick up any changes that occurred since the first snapshot on Monday. I assume that for this final snapshot I would unmount the filesystems to prevent any changes by the customer. Sorry I'm being dense here, I think I sort of get it but I don't have the whole picture.
