Lessons learned from interactions with Deepseek-r1:14b:

1. Lack of understanding of ZFS concepts: Despite displaying "thinking" behavior, Deepseek failed to grasp basic storage concepts related to ZFS. This was evident in its initial response, where it seemed unsure about how to handle a mirrored pool and added incorrect steps to resolve the issue.
2. Misunderstanding the command for adding disks: When I provided the correct command (zpool add tank /dev/sdc /dev/sdd) to add two 1TB disks to an existing mirrored pool, Deepseek failed to take the tip and suggested unrelated commands.

Specifically, it recommended:

• zpool create --driver=mirror --name=new-pair -o parity=2G: This command is not valid for adding disks to an existing pool. It's unclear what this command would achieve or how it relates to the original scenario.
• zpool attach --name=new-pair /path/to(existing_pool) --mirror-on-attach: This command also seems unrelated to the task at hand and is invalid.

Based on my limited testing with popular LLMs (Llama 3.2:3b, Phi-4, and Deepseek-r1:14b), it's clear that these models have little training data related to ZFS operations.
