Using ZFS replication to migrate FreeNAS

[Wolfeman0101]

I've setup ZFS replication on my old FreeNAS box and it looks like the data is on the new box although it hasn't caught up with the snapshots yet. My question is I'm seeing the new FreeNAS drives filling up but I don't see any data. Is that normal? Also once the snapshots catch up what are my next steps to get off the old sever onto the new one?

I'm not sure what you mean here. Where don't you see data? You should be able to go to the folder on the target that is being replicated to and see your folders and data.

After the data is transferred, setup any shares and jails just like on the original, then decide if you'd rather move the IP address from the old server to the new one, or just reconfigure your clients to use the new IP. It kinda really depends on you and your environment.

So on the target I see nothing except 1 folder that has nothing to do with replication. On the PUSH server I have Vol1 going to volume1/Rodgers. When I look at volume1/Rodgers it's empty.

Code:

user@Packers:/mnt/volume1/Rodgers % df -h

Is the "user" folder under "Rogers" something you created manually? If the dataset location for the replication target isn't empty, it will (or should) fail. Can you run du -h from /mnt/volume1/Rogers

PS-I like the naming convention and avatar.

Thanks! GO PACK GO!

The user folder is the home folder for the user I created. I changed the replication to a new empty dataset I created.

Code:

user@Packers:/mnt/volume1/Rodgers % du -h
83k    ./user
84k    .

Is the replication finished? You won't see anything at the destination until it is.

I ditched ZFS replication for RSYNC. I was just having issues with ZFS replication and I'm familiar with RSYNC.
