November 12, 2025Nov 12 I currently have 1 NVME drive formatted as BTRFS used to store non critical data in a share (outside of the array). I'd like to add another NVME drive to expand this storage without adding redundancy as I'm happy to lose data and I want the most space possible.If I understand correctly my only option is to use RAID0 for BTRFS which stripes data across both drives. Meaning if one drive fails I lose ALL data, rather than just whats on that one drive.Is there a way to configure both drives to work effectively as singles but be able to have share spanning both of them (similar to how the array works)?

Is there a way to have a share span two pools then?
November 12, 2025Nov 12 Community Expert You can have a share using the pools, one set as primary, and the other as secondary storage, but the mover will move the data from one to the other.
