Hi, if you have had faulted disks in some raidsets that would explain imbalance as zfs "avoids" writing to them while they are in faulted state. I've encountered similar imbalance but that is due later changes in pool configuration where vdev's were added after first one's got too full. Anyway, this is an issue, as your writes will definitely get slower after first raidsets get more full, as mine did, writes went from 1.2GB/s to 40-50KB/s and freeing up some space made problem go away (total pool capacity was around 60%).
