Watch the bitswap ledger in one terminal.

while true
do
  for peer in $(ipfs swarm peers | awk -F/ '{ print $NF }')
  do
    ledgerdata=$(ipfs bitswap ledger $peer)
    if [[ -n "$(echo $ledgerdata | grep -v '\t0$' | grep -v '\t0.000000$' | grep Bytes)" ]]
    then 
        date
        echo $peer

Start the download in one terminal.

ipfs get -o /tmp/bigfile QmYi6yy3ygc3dNJETqFvvyXdZx28dNyNbZLHkiimhd8Jzd

Note: Do you have it already in your repo? You can remove it, i.e. ipfs repo gc. If the download is stalling, you can do the same download from another node in parallel.

ToDo: What is different, if a peer nearby has the big file already downloaded?
