threshold-statesync

A threshold based statesync script that will automate cosmos validator storage management.

Installation

To prepare to install Threshold Statesync, run the following commands:

sudo su
git clone https://github.com/iprouteth0/threshold-statesync
cd threshold-statesync
chmod +x deploy.sh

Then, run the deploy.sh. The systemd argument can be passed to install using systemd service and timer files. Otherwise, crontab will be used to routinely run the scripts:

# To install with systemd files
./deploy systemd 

# To install with crontab
./deploy

For chains that require snapshots due to oracle files or wasm files not being obtained via statesync;

chmod +x deploy-snapshot.sh

# To install with systemd files
./deploy-snapshot.sh systemd

# To isntall with crontab
./deploy-snapshot.sh

Usage

Depending on the installation method, either the crontab file or the threshold-*.service files control the script behavior. Multiple arguments can be passed to configure the script to your system settings within these files.
