Solana Mainnet RPC - Update Solana Version | SLV

Maintaining a Solana validator includes updating the Solana version.

This page explains how to update your Solana mainnet RPC.

Update SLV Version

To update your SLV validator version, run the following command:

bash
$ slv upgrade

Update SLV Default Version Settings

To update the default settings for your SLV validator, run the following command. Using the --config-only flag will only update the ~/.slv/versions.yml file.

bash
$ slv r update:version --config-only

┌─ Mainnet Validators ───────────────────────┐
  Agave: 2.1.14 → 2.1.16
  Jito: 2.1.14 → 2.1.16

┌─ mainnet Validators ───────────────────────┐
  Agave: 2.2.3 = 2.2.3
  Firedancer: 0.406.20113 = 0.406.20113

┌─ Mainnet RPCs ────────────────────────────┐
  Agave: 2.1.16 = 2.1.16
  Jito: 2.1.16 = 2.1.16
  Geyser: v5.0.1+solana.2.1.16 = v5.0.1+solana.2.1.16

✔ Default versions updated

As shown in the log above, the default settings have been updated.

When there are version changes, they are displayed with ->.

When there are no changes, they are displayed with =.

Apply Solana Version Update

To apply a Solana mainnet update, run the following command.

To apply the update to all validators, run the command without the -p flag.

To apply the update to a specific validator, use the -p flag to specify the validator's public key.

You can also specify multiple validators by separating their public keys with commas.

bash
slv rpc update:version -n mainnet -p <your-validator-pubkey>

Running the above command will update the Solana CLI version on your node.

At this point, the update has not yet been applied, so you'll need to restart your node.

Restart After Solana Version Update

※ ⚠️ Restarting your node will cause it to lose synchronization with the network, so please restart with caution.

bash
slv r restart -n mainnet -p <your-validator-pubkey>

Debug and Monitoring

After deployment, you can debug and monitor your Solana node. You can check the status of your Solana node using the following commands.

Connect to your validator using SSH with the appropriate IP address:

bash
ssh solv@<your-validator-ip>

Check the status of your Solana node:

bash
solv m

solv is an alias for agave-validator -l /mnt/ledger. This setting is added to ~/.profile when deploying the Solana node.
