Chunk 11.1

In this chunk, the assistant focused on getting the QA deployment of the FGW distributed storage system fully operational after the initial setup. The first major task was resolving the kuri service failures caused by "dirty migration" states in the YugabyteDB CQL keyspaces. The assistant identified that the test suite had left migration flags set to `dirty = true` in the `schema_migrations` table for the `filecoingw_kuri_01`, `filecoingw_kuri_02`, and `filecoingw_s3` keyspaces, and fixed them by manually updating the flags to `false`, allowing the kuri daemons on both nodes to start and run successfully. The next cluster of tasks involved configuring cross-node communication. The assistant discovered that the Cluster Topology API was returning empty results because the `FGW_BACKEND_NODES` environment variable was not set. After adding this configuration, the API correctly showed both nodes as healthy. However, cross-node S3 reads failed because each kuri node could only serve data from its local blockstore, not from the peer node. To solve this, the assistant deployed the s3-proxy frontend on the head node, configured it with the proper environment variables (CQL hosts and backend node list), and set it up as a systemd service via the existing ansible roles. This architecture ensures that all S3 requests go through the proxy, which routes them to the correct backend node based on the object's stored metadata. A key theme was the careful handling of configuration and the use of proper infrastructure automation. When the user asked why the assistant was not using ansible, the assistant immediately pivoted from manual SSH commands to updating the QA inventory and deploying the s3-proxy via the existing playbooks. The final verification showed both nodes receiving traffic during the load test, with cross-node read/write operations working correctly through the proxy. The assistant also reverted unintended uncommitted code deletions that removed GC and cache integration code, restoring the repository to a clean state matching the committed milestones.
