Hi All, planning out the pools in my new server. I've got 8 disks for the unraid main XFS array, which has dual parity. I also have a pair of nvme drives which will be a zfs pool for docker and vms. I will also likely have a pair of Samsung 2.5" SATA SSD's as a zfs mirror for cache. I have a homelab 15 so lots of room for drives. I want to create a zfs storage pool for my critical shares, such as immich photos, nextcloud data, etc. I have 7x 4TB Ironwolf hard drives available. Some ideas: 1) 2x 2x-drive mirror vdevs 2) 4 disk raidz2 3) 6 disk raidz2 4) 7 disk raidz3. I have about 4TB of data to store on this pool currently. It will grow slowly as I add new family photos. Due to leaving some space for zfs headroom, options 1 and 2 may not give enough longterm capacity for growth, but at least with option 1, it is easy to expand. Since I already own 7 disks, is option 4 outrageous? Let me know your thoughts.
