Ubuntu 20.04 Bitcoin Core v0.20.1
I start bitcoind as follow:
./bin/bitcoind -conf=/home/blockchain/bitcoin-0.20.1/bitcoin.conf -reindex
After reindex done, and sync to the latest block, I stop bitcoind with cmd as below:
./bin/bitcoin-cli -conf=/home/blockchain/bitcoin-0.20.1/bitcoin.conf stop
And now I start bitcoind again without -reindex and it shows inconsistencies error, and told me need to reindex again.
