How to transfer a node into another chain?

Note

You can use either docker or docker-compose commands.

Attention

Before you start, please, find your node and a chain you intend to move your node into in this file.

To transfer your node into another chain:

1. Stop your node by using one of the following commands:

   docker stop tpnode && docker rm tpnode

   or

   docker-compose down

2. Back up your node by using the following command:

   tar -cvjf ~/thepower_before.tar.bz2 /opt/thepower

3. Delete the database and logs using the following command:

   find /opt/thepower/db ! -path "*/db/cert/*" -exec rm {} \; && rm /opt/thepower/log/*    

4. Edit the configuration:

   1. Delete all data in square brackets in the following line:

      {tpic,#{peers => [], port => 1800, allow_rfc1918 => true}}.

   2. Add the following line:

      {replica, true}.

   3. Add the following:

      {upstream, [
      "Insert_here_your_upstream_link1",
      "Insert_here_your_upstream_link2"
      ]}.
      Attention

      Take the upstream links from the file.

5. Start the node using one of the following commands:

   docker run -d \
   --name tpnode \
   --restart unless-stopped \
   --mount type=bind,source=/opt/thepower/db,target=/opt/thepower/db \
   --mount type=bind,source=/opt/thepower/log,target=/opt/thepower/log \
   --mount type=bind,source=/opt/thepower/node.config,target=/opt/thepower/node.config \
   -p 1800:1800 \
   -p 1080:1080 \
   -p 1443:1443 \
   thepowerio/tpnode

   or

   docker-compose up -d

6. After going through the steps above, make sure that all works correctly:

   curl -s https://<hostname>:1443/api/node/status | jq .status.blockchain.chain,.status.blockchain.header.chain

   where

   • <hostname> is your node name.

7. If the above-mentioned command returns two indifferent values, it means that the node has become a Consensus Node in a new chain. It must be reflected in configuration. To do this:

   1. Stop the node.

   2. Back it up.

   3. Open node.config file in editing mode and make the following changes:

      • Delete {upstream ...}. line,

      • Delete {replica, true} line,

      • Delete db/peers file,

      • Replace {tpic,#{peers ... }}. with a line from the table below, according to your chain number:

        Chain number	Line
        1025	{tpic,#{peers => [{"c1025n02.thepower.io", 41025},{"c1025n04.thepower.io", 41025},{"http://c1025n05.thepower.io", 41025}], port => 41025, allow_rfc1918 => true}}.
        1026	{tpic,#{peers => [{"c1026n3.thepower.io", 41026},{"c1026n6.thepower.io", 41026},{"power-node.allsteeply.com", 41026}], port => 41026, allow_rfc1918 => true}}.
        1027	{tpic,#{peers => [{"c1027n7.thepower.io", 41027},{"thepower.lefey.ru", 41027},{"c1027n10.thepower.io", 41027}], port => 41027, allow_rfc1918 => true}}.
        1037	{tpic,#{peers => [{"c1037n2.deinfra.net", 1800},{"tpnode.nova-network.systems", 1800}], port => 1800, allow_rfc1918 => true}}.
        1038	{tpic,#{peers => [{"c1038n5.deinfra.net", 1800},{"c1038n6.deinfra.net", 1800},{"c1038n12.deinfra.net", 1800}], port => 1800, allow_rfc1918 => true}}.

      • Check tpic ports:

        • for chains 1025, 1026, 1027 actual ports are 41025, 41026,41027.

        • for chains 1037 and 1038 actual port is 1800.

          Attention

          Please, specify these ports in node start-up command or in docker-compose.yml.

      • Save changes.

      • If you had a Consensus Node, exclude genesis.txt from start-up command or from docker-compose.yml.

      • Start the node.

      • Check that your node is working. The above-mentioned command must return same chain numbers, and a temporary must change.

   Then you will get two numbers: zero and a new chain number. As a first value, you'll get zero for Seed Nodes and an old chain number for Consensus Nodes.
