February 22, 20242 yr I currently have two pools configured. Pool 1 is the "system" drive, storing appdata, domains, etc. This is a 2x512Gb NVME btrfs raid 1. This pool is working great for me. Pool 2 is my "work" drive. It's the write cache for the array, as well as storage for downloads/processing files. Right now, this is a 2x1Tb SSD btrfs raid 1. I'm looking at options for expanding pool 2, with it's primary job to remain as a "work drive", so I need a combination of speed & size, but maintaining at least some level of redundancy. The raid1 level that I'm currently using takes away 50% of the space, and gives no beneficial speed benefits. I can easily add 4 more 1Tb SSD's to that pool, but probably not all at once. I'm not sure what filesystem would be the best in this use case, and I only know that ZFS exists, but I've never used it. So, what would be the best filesystem in this use case? Because it's only storing data temporarily, I'm not as worried about being able to expand the pool as I add more drives, but I'd like to get started on it now, with the 2 drives I currently have, so that I can start getting used to it. Or, if it's best to leave it as-is until I add at least 2 more drives, I have no problem with that, but I'd still like to hear what suggestions everyone has.
