I build my (almost) fanless home server. 00:00 Intro 00:34 Build 23:45 Stuck button breaks BMC 27:05 BMC and BIOS settings 33:30 Proxmox Install with network ISO 37:40 Proxmox network config 40:40 Temperatures 41:01 SR-IOV for PCI passthrough 41:23 Hot temperatures with rsync + ZFS 43:36 Chipset fan 46:21 Fan speed settings 47:41 TrueNAS: transfer files from old RAID array 50:03 Stress testing for temperatures Parts list: * Nofan CS-70 case * Nofan P-400A PSU * Ryzen 5600 CPU * Noctua NH-P1 cooler * ASRock Rack X570D4U motherboard * Micron 2x32GB ECC RAM 3200 https://uk.crucial.com/memory/Server-DDR4/MTA18ASF4G72AZ-3G2R Idle power is around 35W with disks spun down; 45W with disks running. Transferring from mdadm RAID 1 (mirror) array to ZFS mirror vdev: 1) Backup to third disk (at least) 2) Use this command on Proxmos terminal to identify IOMMU groups: cat /proc/cmdline; for d in /sys/kernel/iommu_groups/*/devices/*; do n=${d#*/iommu_groups/*}; n=${n%%/*}; printf 'IOMMU group %s ' "$n"; lspci -nns "${d##*/}"; done 3) Create VM for TrueNAS and pass through the device with the SATA controller 4) Install TrueNAS and choose one of the disks to make a single disk stripe vdev 5) Create a dataset on the pool 5) Export the new pool then shut down TrueNAS VM 6) Create and start a Debian or Ubuntu VM with same hardware settings 7) On that VM, mount the old mdadm RAID array: i) sudo mkdir /mnt/oldraid ii) sudo mdadm --examine /dev/sdd1 # trial and error /dev/sd* to find the right disk iii) sudo losetup --find --show --offset=134217728 /dev/sdd1 #offset is 8x result from examime command iv) sudo mount /dev/loop6 /mnt/old_disk/ 8) Mount the new ZFS disk: i) sudo zpool import # will list the available pools ii) sudo zpool import my_pool # add -f switch if you forgot to export iii) sudo zfs load-key -L prompt my_pool/my_dataset v) sudo zfs mount my_pool/my_dataset 9) Copy files: rsync -av --progress /mnt/old_disk/* /my_pool/my_dataset/ 10) Unmount/export: zfs export my_pool 11) Shutdown Debian/Ubuntu VM; start TrueNAS VM; remember to unlock dataset if encrypted
