Solana 1.9.x Release Overview For Validators

The new 1.9.x release will be landing in mainnet soon. Here are some important new features to be aware of for validators:

1. Incremental snapshots

Snapshot size has become very large (On the order of 20 to 30GB to get a validator up and running). This change creates smaller incremental snapshots. Important: Once a validator starts using incremental snapshots, it cannot go back to version 1.8.

Recommended Upgrade Procedure:

Step 1: Create sol User With SSH Access

Assuming you are logged into the remote machine with sudo privledges

sudo useradd sol
sudo usermod -aG sudo sol

Next verify that the sol user has sudo privledges:

sudo ls /root/

The Alpenglow community cluster is ready for validators to join! The cluster is currently waiting for super majority to start. Validators will likely join over the next few days. If you are not part of the gensis set, we can delegate to your validator afterwards.

Operators should do the following to join the cluster:

Checkout the alpenglow branch from Ashwin’s github:

git clone https://github.com/AshwinSekar/solana.git agave
cd agave
