Workaround: restart bitcoind.
Problem:
/usr/bin $ ./bitcoin-cli createwallet hello true
error code: -1
error message:
BerkeleyBatch: Error 2, can't open database wallet.dat
That's the end result, but before the error, here's what I did...
Steps to reproduce:
/usr/bin $ ./bitcoin-cli createwallet hello true
{
"name": "hello",
"warning": ""
}
/usr/bin $ ./bitcoin-cli createwallet hello true
error code: -4
error message:
Wallet hello already exists.
/usr/bin $ ./bitcoin-cli unloadwallet hello
/usr/bin $ ./bitcoin-cli createwallet hello true
error code: -4
error message:
Wallet hello already exists.
/usr/bin $ rm -rf /.bitcoin/testnet3/wallets/hello
/usr/bin $ ./bitcoin-cli createwallet hello true
error code: -1
error message:
BerkeleyBatch: Error 2, can't open database wallet.dat
/usr/bin $ ./bitcoin-cli --version
Bitcoin Core RPC client version v0.17.0
I was working in an Alpine docker container on an OSX host.
