Rebuilding pools - cannot find migrated files

[raspino]

I have added a new drive to my freenas box so I can increase an existing pool of 3 10TB drives (zpool one) to 4 10TB drives . I also have a second pool that has two 10TB drives (zpool two). I took a snapshot of the data in the zpool one and sent it to zpool two which appeared to have worked but I cannot find the data in zpool two because when I cd into the pool, I don't see the data I sent. It appears the send command worked because when I attempt to send the snapshot to zpool two again, I get the following error:

root@freenas[~]# zfs send -R zpoolone@migrate | zfs recv -Fv zpooltwo
cannot receive new filesystem stream: destination has snapshots e.g. zpool@migrate) must destroy them to overwrite it warning:

How do I confirm that the send command work if I cannot find the files in the zpool two ?

You should be able to see the directory tree and all the files. Check zfs list to see if there is data on the pool

I checked zfs list and unfortunately I don't see it in the directory. zfs list shows only the top level name of the pool and other system paths but not the data files I copied. When I cd into the pool, I am able to see all existing files that were already in the pool but not the new ones I sent. Puzzling.

You did the replication wrong. Try again and remove the snapshot on the destination

Do you mean, this is wrong ?
root@freenas[~]# zfs send -R zpoolone@migrate | zfs recv -Fv zpooltwo ?

Well it's wrong because it didn't work. No clue what you did wrong. Try giving it a pool/dataset for the recv side, not just the pool.

 

[raspino]

how do I specify the data set. Perhaps start from where I create a new dataset.

 

[raspino]

I created the new data set so I just have to specify it in my send/receive command.
root@freenas[~]# zfs send -R zpoolone@migrate | zfs recv -Fv zpooltwo ?

 

[raspino]

I think I found out how to do it. I will check to see if the files transferred correctly after the send/receive is finished.

 

[raspino]

It worked. I am able to see the files now.
