Overview

The instructions below will fully install Heimdall's data folder by downloading each file individually instead of working with zipped archives. In short, download the file that will tell aria2c which files to download and which directory to save them to. Then, use aria2c to download all of the Heimdall files. Last, modify the ownership of the files so Heimdall can access them.

Pruning

Our snapshot is pruned to provide a smaller option for node operators who don’t need a to query Heimdall. Below are the settings we changed to prune:

# /var/lib/heimdall/data/config/config.toml

[storage]

discard_abci_responses = true
compact = true
compaction_interval = 1000

[storage.pruning]

interval = "2h" 
indexer_pruning_enabled = true

# /var/lib/heimdall/data/config/app.toml

min-retain-blocks = 2500000

Download and Install

1. Navigate to the folder with your data folder in it, then download the file containing which files to download. You might need to do this as the root user.

cd /var/lib/heimdall
rm -r ./data
wget <https://snapshots-eu.vaultstaking.com/polygon/heimdall-mainnet-files.txt>

1. Open tmux or use screen/nohup to keep downloading after you close your connection.

tmux

1. Download the files using aria2c.

sudo aria2c -j 4 -x 4 --console-log-level=warn --auto-file-renaming=false --summary-interval=3600 -c -i ./heimdall-mainnet-files.txt

3. This will download files with root ownership. Change all files to be owned by heimdall and the nogroup group

sudo chown -R heimdall:nogroup /var/lib/heimdall

1. Start Heimdall and let it catch up.

sudo service heimdalld start
