Hello, Monaparty node administrators.

How about your happy Monapaty festa in autumn?

This article describes how to upgrade your federated node.

Why special ?

“Node upgrade in fall, 2020” is a big upgrade. So you must do some more tasks than usual.

Step by Step

Uninstall older version

fednode uninstall

Don’t worry. Docker volumes is kept back.

Switch your branch to monaparty and pull commits.

cd fednode/
git checkout monaparty
git pull

Finally federated node supports monaparty (means the stable master) branch. I strongly recommend run your nodes with this branch.

Of course, you can keep using monaparty-develop. But it’s a breeding edge.

Check configuration

fednode configcheck

Brand-new indexd-server support is added in this upgrade. So there will be some differences between your configuration and official’s.

Please fix them.

You may use for i in config/*/*.default; do cp $i $(dirname $i)/$(basename $i .default); done if you see it.

Install new nodes.

fednode install full master

In case you don’t want to install Counterwallet, you can use fednode install counterblock master or fednode install base master instead.

Update nodes.

fednode Update

In this version of fednode have some bugs. So you must run update command.

In horrible, the update process is finished with an error like this.

Fatal error: Invalid checksum: src/vendors/bitcoinjs-lib/bitcoinjs.min.js

But. It’s OK for now even if you might not believe me. Trust.

Just wait for 2 or 3 days.

The database will run full re-parse. It will required 2 or 3 days.

extra: In case re-parse was stopped with inconsistency.

In some cases, re-parse may be stopped with the transaction inconsistency.

You can resolve this by deleting old databases.

Here is the step-by-step.

Stop Counterparty servers

fednode stop counterparty
fednode stop counterparty-testnet

Check the local path for the volume

docker volume inspect federatednode_counterparty-data

You will get result like this.

[
    {
        "CreatedAt": "2020-10-01T05:54:04Z",
        "Driver": "local",
        "Labels": null,
        "Mountpoint": "/var/lib/docker/volumes/federatednode_counterparty-data/_data",
        "Name": "federatednode_counterparty-data",
        "Options": null,
        "Scope": "local"
    }
]

"Mountpoint" is the target.

Remove database related files

sudo sh -c 'rm /var/lib/docker/volumes/federatednode_counterparty-data/_data/monaparty.db*'

The path should be arranged to fit your environment.

Restart servers

fednode start counterparty
fednode start counterparty-testnet

Pray

The latest database image may be downloaded if you are lucky. :-)

If you aren’t, the full re-parse process may be run. ;-) Please wait for 2 or 3 days.
