Features


Migrate Node​

This feature enables users to seamlessly transfer or migrate their shards to new nodes, particularly useful when encountering issues like corrupted files on their existing nodes.

Requirements​

  • Auth-Key: The auth-key of the node from which shards are to be recovered. Without this key, moving the node is not possible.
  • Node Migration: If migrating due to hardware failure, the new node's commitment and specifications should match those of the old node.

Functionality​

  • Shard Recovery: Recovers shards on the node in case of accidental deletion or hardware failure.
  • Recovery Time: Full shard recovery may take hours or days.
  • Reputation Impact: Frequent migrations may result in reduced reputation or reputation slash.

Steps to migrate devices:​

Access The Move Nodes Option​

  • Open the Storage Nodes page of the web dashboard.
  • Select Node Details on the node you'd like to migrate.
  • Select the 3-dot menu to reveal the Move Node option.

Inserting Auth Key​

  • After selecting "Move Node" a dialogue box prompting us to insert the auth key will appear.
  • Enter the auth key and click on the "Begin" button to initiate the shard moving process, as shown in the screenshot.
note

The changes will be reflected within hours or days.


Resize Node​

Once a node operator stakes the IAG equivalent to their initial storage commitment, they have the option to increase the storage commitment any time while the node is active. When resizing, the operator must sign and submit a new Cardano transaction. This transaction includes an additional stake equivalent to the amount of storage being added, based on the staking calculation formula.

Requirements​

  1. The updated storage amount should be greater than the already provided storage.
  2. The node must be online during the resizing of the device.
note

If the resizing is to be done by changing the storage hardware device, the storage node app has to be installed on the new device, using the same auth-key of the node. In such case, the shards on the node will be recovered gradually.
