I had to do a zfs send | zfs recv to move data form a single disk back to a raidz1 pool.
The single disk was using 1.83T of space but when I ran the command: zfs send Backup@now | zfs -dF Data, the space is now taking up almost double on the new raidz1.
Is this normal? I would assume that there is some parity information but I wouldnt assume this much. Here is the output right now from iostat while the send/recv command is still running. It looks like it moves the snapshot over then "decompresses it"?? I dont use compression and the original pool was not compressed.

I tried the search box, but nothing come up about this. THanks. :)
