Playbooks to install a Kava node with Chainlayer Quicksync
- on your local machine install ansible
- make sure you have ssh-key access to the target machine with either root or a user with sudo rights
git clone https://github.com/chainlayer/quicksync-kava.git
# edit group_vars/kava.yml file
vim group_vars/kava.yml
# edit ansible-hosts.yml file
vim ansible-hosts.yml
cd quicksync-kava
./quicksync
If for whatever reason the download is cancelled, you can resume it manually (assuming default variables):
sudo su - kavauser
cd /home/kavauser
aria2c --continue -x 5 https://get.quicksync.io/kava-7-pruned.20210624.0210.tar.lz4
cd .kvd
tar -I lz4 -xf /home/kavauser/kava-7-pruned.20210624.0210.tar.lz4
exit
# enable and start kava with sudo
sudo systemctl enable kvd
sudo systemctl start kvd
Downloading the blockchain using the quicksync option can take a long time! Ansible will not give you any feedback unfortunately. You can check if aria2c is still working by checking top on the host or checking the aria.log file in the download dir for progress
You need enough harddisk space to store the download as well as the unpacked chain, lz4's compression rate is roughly 30% so you would need at least 2,4 time the download size in disk space. A variable called cl_download_dir can be used to specify a different download directory, that way you could add a temporary second disk for the download and remove it afterwards.
Normally Ansible playbooks are idempotent meaning you can run them multiple times with the same result. This playbook should be idempotent as well however running it a second time will download the whole quicksync another time and is therefore not recommended.
