Error: Unpack directory 'db' already exists, please move or delete it -- on arm64

[TheStophe]

I'm getting this error in the logs after a few hours of downloading (seen using docker stats). This repeats upon node auto restart continuously.

So on my archlinux arm64, I pulled the image using

docker pull ghcr.io/blinklabs-io/cardano-node:8.9.1@sha256:4ad71c0a4bbf09c01e93d583d646ea9d951312026968d9173017762b9e814708

From latest package 8.9.1

https://github.com/blinklabs-io/docker-cardano-node/pkgs/container/cardano-node

I run the docker container startup using

docker run --detach \
  --name cardano-node \
  --restart unless-stopped \
  -e CARDANO_BLOCK_PRODUCER=false \
  -e CARDANO_SHELLEY_KES_KEY=/opt/cardano/config/keys/kes.skey \
  -e CARDANO_SHELLEY_OPERATIONAL_CERTIFICATE=/opt/cardano/config/keys/node.cert \
  -e CARDANO_SHELLEY_VRF_KEY=/opt/cardano/config/keys/vrf.skey \
  -v /src/cardano/node-keys:/opt/cardano/config/keys \
  -v /srv/cardano/node-db:/opt/cardano/data \
  -v /srv/cardano/node-ipc:/opt/cardano/ipc \
  -p 3001:3001 \
  -p 12798:12798 \
  ghcr.io/blinklabs-io/cardano-node run

When I check /srv/cardano/node-db after the error posts, the /srv/cardano directory only has the node-keys dir made (node-db) does not exist.

I then deleted the entire container and ran it again with /srv/cardano/node-db directory made. Still the same "Unpack directory db" error.

[TheStophe]

Note: All my directories for node-db and node-ipc are empty, maybe a permissions thing?

[wolf31o2]

This should be resolved in 8.9.2, where we updated Mithril to a version that has this fixed.

[wolf31o2]

Can you try this again with an 8.9.2 image?

[TheStophe]

I tried it again, looks like a slightly different error. At first the docker run command does nothing. Had to chmod the data/db with

sudo chmod -R 777 /opt/cardano/data

then here's the second run.

docker run --detach \
  --name cardano-node \
  -v node-data:/data/db \
  -v node-ipc:/ipc \
  -e NETWORK=mainnet \
  -p 3001:3001 \
