Hello All
Wadding some drives and another pool to a previously established FreeNas system in production. I am adding some 6TB HGST NAS drives. I think I am seeing some weird Parallel test from the Solnet Array Test, but can't figure out why. What do you make of this?
Drives are all on a single SAS2 Channel, but I don't think that is the bottle neck.
