  1. Attempting to add new nvme drive cache leading to 'Wrong Pool State "Invalid Expansion"'

    Matthew Flower posted a topic in General Support
    I currently have a single nvme drive in my cache pool with 723 GB of data on it. I've recently installed a second nvme drive, with the intention of adding it to the cache pool. I took the array offline, set the cache pool to two slots, and added my new drive to the pool. When I attempted to bring it back online, I received the error in the subject. I previously read this post with a similar error message, but it wasn't 100% clear to me if its the exact same problem or if there may be a different solution now. Is deleting and recreating the cache pool the right move? Should I be trying to use the mover to clear out the cache first? Thanks in advance for any advice you might have.
