DB errors in Armory prevent sending bitcoin

Problem solved, and thanks for all the help! The issue seems to have been on the bitcoin core side.

I actually already tried rebuilding ArmoryDB (deleting the whole databases folder in between) and it seems to fail at the same block file.

I spun up a new VM running the same docker environment, but doing a fresh bitcoin download this time to see if maybe there is something actually wrong with my bitcoin database. Everything worked correctly with the new bitcoin database.

It complains that it cannot find older blkXXXXX.dat files, in this case blk02641.dat. Can you confirm that file is in your blockchain data folder? Im going to assume it is for the remainder of this post.

Quote

"ArmoryDB --db-type=DB_BARE --ram-usage=1"

This setting is too approximative, the main way to clamp memory usage in ArmoryDB is by reducing thread count (--thread-count=X).

I don't know how memory is managed between containers and host. I've ran into the oomkiller a few times when running beefy containers + using a bunch of memory on the host (im on arch) and while the system recovers, a lot of processes blow up unpredictably. I can't tell if you're running in this issue because of corrupted data or because of weirdness with resource load within containers.

My suspicion is that a parser thread dies mid scan and you're seeing the consequences of that (block files are grabbed as whole, this would explain one file failing to scan entirely). --ram-usage controls how many block files can be parsed concurrently. Bitcoin Core keeps block files within 128MB so that's a proxy for memory usage in ArmoryDB. --thread-count limits the amount of threads the scanner gets to use and is a better predictor of resource load.

This is what I suggest for now:

1. Try to rescan (not rebuild) your db. If it fails at a different block file, then you are running into a concurrency issue. Toy with --ram-usage and --thread-count, maybe it will pass.
2. If it fails at the same block file, delete your database folder and try again. Does it fail at the same block file again during the new scan? It's possible the concurrency issue hit during the build phase and you're seeing the symptoms at the scan phase
3. In general, this is old code I haven't looked at in a while. If this problem persist, I'd invite you to try out the new code in the dev branch, as that's stuff I can realistically debug and fix.

OK, I've tried deleting the database folder and restarting everything. It goes well until it get a "Missing file map for output scan, this is unexpected" error. I also updated my Dockerfile to run everything as a regular user.

I did find this thread https://bitcointalksearch.org/topic/armory-is-not-scanning-transaction-history-3055574 referring to that error back in 2018. I'm not sure whether it's still applicable. My bitcoin node is definitely online in this case and is keeping in sync.

Not sure if "ArmoryDB --db-type=DB_BARE --ram-usage=1" as mentioned in that thread would be helpful here either.

I'm going to try doing a rebuild instead.

You're better off delete Armory's databases folder in this case (/root/.armory/databases)

I'd suggest you run as user instead of root too. You can add the following to your dockerfile:

Code:

#add the user while in root
ARG USERNAME=armory
RUN useradd -ms /bin/bash $USERNAME

#switch to user
USER $USERNAME

#run build steps here

I started running it in docker just because I had a bunch of issues getting it to build on Ubuntu 22.04 and it provided a good way to get an environment where could build everything and have it work correctly. The docker container has all of Armory and Bitcoin in it, so I'm not trying to containerize the individual components, just manage the environment that way.

I tried to run ArmoryDB --rescan by itself and it looks like the actual ArmoryDB process is just crashing shortly after starting the rescan. I'm going to try doing a rebuild instead.

Are you trying to dockerize it because you're on a Windows host or is there another reason? Depending on what you're trying to achieve, I can help you with the docker file or the setup as a whole. If you're armed with patience, you could help me make the dev branch user friendly (at least the build & launch steps). That stuff works (I've been using it for my own stuff for over a year now), I just cant get around to make it user friendly. At any rate, a few notes:

1. ArmoryDB tracks the addresses in your wallets. If it sees them once, it will know then until you wipe/rebuild the "databases" folder (what the --dbdir argument points at). Since your db knows your addresses (it wouldn't try to scan otherwise), you can run "ArmoryDB --rescan" on its own (without either ArmoryQt or Core running) to get better verbose.

2. Dockerizing ArmoryDB isn't really useful imo. This is a headless C++ process, it doesn't have any linkage with Qt nor any other GUI library, it's the easiest part of the puzzle to build & run on any host OS. It needs read access to blockchain data and ~10GB for itself persisted across runs, so you will have to mount part of your host file system in there in all likelihood. It also mmap's the blockchain data, I don't know how docker/containerd/k8s deals with that. On the other hand, it talks to ArmoryQt via a socket, so you can run ArmoryDB and Core on your host, and containerize the client.

3. Containerizing the client is your best return on investment, this is where all the exotic requirements come from. I would run as a user, setup a python venv and install the dependencies via pip off of a lightweight image. This could probably work on alpine. I expect the main hurdle is to expose something that looks like a X server to the image.

Thanks! I've been running a rescan since you posted, but I'm not sure if it's stuck. The progress bar is at 100%, and the spinner next to it isn't moving. CPU usage is at 100% for the armory python process though. I'm not sure if I should be seeing any indication of progress. Should I wait it out some more, or is it time to try something else?

Do I need to upgrade bitcoin core to a newer version? Is this the pruning issue I've seen mentioned?

You can update Core but make sure to disable blockchain data pruning or it will erase historical block data from your disk, which Armory requires.

Rebuild my blockchain db? Anything else I should try?

Hard to say without seeing the full log file. From what you're showing, looks like some db data is mangled. I suggest a rescan, not a rebuild (yet).

I have an armory instance running with bitcoin core 0.20.0 and armory 0.96.5. It loads and I can see a balance in my wallet, but I cannot send any bitcoin from it. Clicking the "Send Bitcoins" button results nothing happening in the GUI and the following errors on the console:
