 Some notes on setting up a new Proxmox server:
+  * Install on ZFS root (set advanced options ''ashift'' to either 9 for 512-byte sector ssds, or 12 for 4k sectors)
+    * (Check what sector sizes an SSD supports with ''nvme id-ns -H /dev/nvme0n1 | grep "Relative Performance"''
   * Run community [[https://community-scripts.github.io/ProxmoxVE/scripts?id=post-pve-install|post-pve-install]] to enable open-source repos, update and disable nag screen
   * Join node into cluster (datacenter->clusters grab join info from existing cluster, join cluster on new node)
