Hi all, I am a bit confused. I thought that if I have a RAIDz2 with 2x3tb and 2x2tb disks, then (since there is a 2 drive redundancy) I should only have 2tb storage available, but I seem to have 3tb?!? I guess that I can lose the 2x3tb and still have >2tb data on the 2x2tb disks… reading old posts seems to point towards space being the smallest disk, but has this changed?
Ignore the degradation, I am in the process of removing the GELI encryption. according to How to remove encryption from a ZFS volume (while keeping the data) | TrueNAS Community
