+===== Upgrading =====
+Always upgrade with ''dist-upgrade'' !
+<code bash>apt update && apt dist-upgrade</code>
 ===== Installation =====
+  * BIOS:
+      * Enable VT
+      * Enable IOMMU
   * Choose ZFS
     * Leave some free space on HDD for swap partition
       * Click "Advanced Options" and manually set "hdsize"
-      * On system with 2x 2TB HDDs, Proxmox installer on ZFS RAID1 propose only ''hdsize=953MB''
+      * Installer 6.1-2 BUG: On system with 2x 2TB HDDs, Proxmox installer on ZFS RAID1 propose only ''hdsize=953MB''. This issue gone with Proxmox 6.2.
     * Do not create swap on ZFS zvol!
   * reboot
   * manually configure  VLAN network from console [[https://pve.proxmox.com/wiki/Network_Configuration#_vlan_802_1q|VLAN 802.1Q]]
+    * check if it is still necessary. Perhaps enabling ''VLAN aware birdge'' from GUI is enough

+==== issues ====
+=== initramfs ===
+Proxmox installed on ZFS RADI1. After reboot, Proxmox boots into initramfs.
+From initramfs console:
+<code bash>
+zfs list
+Try running '/sbin/modprobe zfs' as root to load them.
+</code>
+REASON: no root cmdline, because UEFI boot was used instead of grub loader.
+SOLUTION: force legacy boot in BIOS
+OR TRY:
+<code bash>
+echo -n " rootdelay=5" >> /etc/kernel/cmdline
+pve-efiboot-tool refresh
+</code>
+=== initramfs ===
+REASON: ZFS invoked too soon: [[https://pve.proxmox.com/wiki/ZFS:_Tips_and_Tricks#Boot_fails_and_goes_into_busybox]]
+<code bash>
+modprobe zfs
+zpool import -N -f rpool
+exit
+</code>
 ==== post-installation tips ====
+  * set MAC address prefix: `Datacenter` -> `Options`. Locally Administered Address Ranges are: <code>x2-xx-xx-xx-xx-xx
+x6-xx-xx-xx-xx-xx
+xA-xx-xx-xx-xx-xx
+xE-xx-xx-xx-xx-xx
+</code>
+  * Speedup migrations to set unencrypted network traffic (in secured networks!): <file /etc/pve/datacenter.cfg>
+migration: network=first_cluster_host_ip/22,type=insecure</file>
   * disable subscription repo:\\ <code bash>sed -i.bak 's|deb https://enterprise.proxmox.com/debian/pve buster pve-enterprise|\#deb https://enterprise.proxmox.com/debian/pve buster pve-enterprise|' /etc/apt/sources.list.d/pve-enterprise.list</code>
   * add no subscription repo: <code bash>echo 'deb http://download.proxmox.com/debian/pve buster pve-no-subscription' > /etc/apt/sources.list.d/pve-no-sub.list</code>
-  * upgrade
+  * <code bash>apt-get update</code>
-  * SMART disk monitoring\\ <file | /etc/smard.conf>
+  * <code bash>apt-get upgrade</code>
+  * <code bash>apt-get install dropbear busybox-static --no-install-recommends</code>
+  * Update grub config: <file | /etc/default/grub>
+GRUB_CMDLINE_LINUX_DEFAULT="rootdelay=15 mitigations=off panic=30 nomodeset textonly video=vesafb:off video=efifb:off"
+</file><code bash>update-grub</code>

-  * (NOT NEEDED) Activate ZFS e-mail notification [[https://pve.proxmox.com/pve-docs/pve-admin-guide.html#chapter_zfs]]
+  * Activate ZFS e-mail notification [[https://pve.proxmox.com/pve-docs/pve-admin-guide.html#chapter_zfs]]
+    * <code bash>systemctl enable --now zfs-zed</code>
   * Use own internal CA signed cert for Web UI: [[https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysadmin_certificate_management|Certificate Management]]
     * For clustering Proxmox is using own self signed certs! Do not replace them!
+  * Postfix relay:<code bash>apt-get install postfix bsd-mailx
+wget https://raw.githubusercontent.com/Tontonjo/proxmox/master/ez_proxmox_mail_configurator.sh
+bash ez_proxmox_mail_configurator.sh
+</code>
+  * Assign admin permissions: [[https://pve.proxmox.com/wiki/User_Management#_real_world_examples]]
+  * For HDDs storage, limit Proxmox operation speed to 50000KiB: <code bash>pvesm set local --bwlimit default=50000</code>
+    * to remove limit: <code bash>pvesm set local --delete bwlimit</code>
+  * Enable IOMMU
+    * in `GRUB_CMDLINE_LINUX_DEFAULT` and add kernel parameter `intel_iommu=on` or `amd_iommu=on`
+    * <file /etc/modules>
+vfio
+vfio_iommu_type1
