feat(pallet-tfgrid): allow `hdd only` nodes to register on chain #971

Closed renauter closed 5 months ago

renauter commented 6 months ago

Description

We want to allow registration of HDD only nodes on chain for Holochain usage.

Implemented solution:

  1. Similar to what already exists for SSD, add a minimum HDD size requirement on resources.validate_hru()
  2. Then, on validating, make sure node has at least 1 minimum storage capacity available 
    ensure!(resources.validate_hru() || ensure!(resources.validate_sru() , Error::<T>::InvalidStorageInput);

A "reasonable" minimum HDD size requirement is set to 100 GB (same as SSD).
