Please upgrade Flow Verification node to v0.33.20-patch.1

hello Verification @Node Operators -

The height coordinated upgrade is now complete.

If you are running a Flow Verification node, please upgrade your node to docker tag v0.33.20-patch.1 or alternatively, v0.33.20-patch.1-without-netgo-without-adx or v0.33.20-patch.1-without-adx or v0.33.20-patch.1-arm as per your hardware.

Optional Steps

After the node restarts, if you observe that the disk usage on the node spikes unusually high, you can do the following to avoid running out of disk space:

  1. Stop the node.

  2. Move the data folder (mv /var/flow/data /var/flow/old_data - adjust the path to the data directory as per your setup)

  3. If the file /var/flow/bootstrap/public-root-information/root-protocol-state-snapshot.json exists, rename it to something else. (mv /var/flow/bootstrap/public-root-information/root-protocol-state-snapshot.json /var/flow/bootstrap/public-root-information/root-protocol-state-snapshot.json_old)

  4. Add the following docker flags to allow the node to use dynamic bootstrapping to come up,

--dynamic-startup-access-address=secure.mainnet.nodes.onflow.org:9001 \
--dynamic-startup-access-publickey=28a0d9edd0de3f15866dfe4aea1560c4504fe313fc6ca3f63a63e4f98d0e295144692a58ebe7f7894349198613f65b2d960abf99ec2625e247b1c78ba5bf2eae \
--dynamic-startup-epoch-phase=EpochPhaseStaking

  1. Update the docker tag to v0.33.20-patch.1 or alternatively, v0.33.20-patch.1-without-netgo-without-adx or v0.33.20-patch.1-without-adx or v0.33.20-patch.1-arm as per your hardware (if not already done).

  2. Start the node.

  3. If the node running is OK at this point, delete the backup folder rm -rf /var/flow/old_data and the root snapshot file rm -f /var/flow/bootstrap/public-root-information/root-protocol-state-snapshot.json_old.

We observed that a verification node may experience a large spike in disk usage when coming up hence suggesting moving the data folder in step 2 and using dynamic bootstrapping which lets the node start off the current block height.

Please make this change in the next 24 hours.

As per policy, rewards will be withheld if the node is not updated within 24 hours.

No action is needed from other node types.

Thank you,
Flow Foundation
