Did you correctly stopped bitcoind before copying the state directory ?
Sure. Here is the script that stops my bitcoind. Is this correct stopping?
[suser@power ~]$ cat /home/suser/bitcoin-core/.bitcoin/stop.sh
#!/bin/sh
if [ -f /home/suser/bitcoin-core/.bitcoin/bitcoind.pid ]; then
kill $(cat /home/suser/bitcoin-core/.bitcoin/bitcoind.pid)
fi
I stopped it before copying. I am using bitcoin core 0.16.0
