I think a faced a badly balanced pool after adding more disks many years
ago, and just wrote the files to themselves using rsync or similar to make
zfs rebalance them. After doing a bit of google, I just found this script
which appears to to something similar (although it creates a real copy
first and does not write files to themselves directly):
