Previously discussed here: LoadBlockIndexDB: transaction index disabled but thread was abandoned. Started a new thread here.

Twice I have gotten the same error:

2018-11-20 15:43:41 LoadBlockIndexDB: transaction index disabled 2018-11-20 15:43:41 : You need to rebuild the database using -reindex to change -txindex. Please restart with -reindex or -reindex-chainstate to recover. 2018-11-20 15:43:41 Aborted block database rebuild. Exiting.

Here is my procedure that results in the error:

  • Shutdown bitcoind on server #1
  • ran rsync -Lru --info=progress2 /path/to/blockchain /path/to/external/usb (note: /path/to/external/usb is a BLANK directory on the external drive)
  • unmounted external USB
  • plug into Raspberry Pi, boot
  • Made sure blockchain was visible in /home/USER/.bitcoin
  • Ran bitcoind at the terminal.

Notes:

  • txindex is turned on in bitcoin.conf on server #1
  • txindex is also on in bitcoin.conf in /home/user/.bitcoin. on the raspberry pi I can verify bitcoind on the raspberry pi is loading that exact .conf, see the log below.
  • commenting out #txindex in the bitcoin.conf file and simply running bitcoind with no flags results in a successful startup.

Here's the output of my log file when it failed:

I COULD just run bitcoind -reindex but that doesn't solve the problem of 'what is causing the txindex database to not work between machines.' I feel like this is an important question to answer.

    Are you using the same version of Bitcoin Core on both machines? Which files and directories are you copying over (give filenames, not just "blockchain") Commented Nov 20, 2018 at 16:47
  • Server #1 BCC version: 0.17.0.1 Raspberry Pi BCC version: 0.16.3 I'm copying the entire bitcoin directory including: banlist.dat, bitcoin.conf, blocks, chainstate, database, debug.log, fee_estimates.dat, indexes, mempool.dat, and peers.dat I bet the version difference is the problem. I'll upgrade BCC on the RPi Commented Nov 20, 2018 at 18:35
  • Yes, in 0.17 the format of the txindex changed, so 0.16 will see it as a database without txindex. Commented Nov 20, 2018 at 18:48

Bitcoin Core 0.17.0 changed how the txindex is handled. The txindex is no longer stored where it used to be, so using a data directory from 0.17.0+ with an older version of Bitcoin Core will result in the older version not recognizing the txindex. You will need to upgrade your raspberry pi to use Bitcoin Core 0.17+.
