====== ProxMox Notes ======

===== Post-Install Tasks =====
==== Disable/remove the annoying "no subscription" message that pops during login ====
Visit https://free-pmx.pages.dev/tools/free-pmx-no-subscription/ and install the package located there.

==== Set up notification emails ====
Datacenter > Notifications

==== Set up remote syslogging ====
  apt update && apt -y install rsyslog
Once installed, edit /etc/rsyslog.conf and add the following section to the bottom; provide the proper IP address where noted:
  # Remote syslog config
  *.info;daemon.notice;authpriv.* @<log aggregator IP>:514

==== Install lshw ====
  apt update && apt -y install lshw

==== Suppress repeated smartd alerts ====
Edit /etc/smartd.conf and add entries such as the following:
  /dev/sda -C 197+ -C 198+
This will cause smartd to send emails only if the selected parameters increment; otherwise emails get sent every 24 hours as long as the values remain non-zero (which they always will once they aren't).

===== Useful Notes and Tips =====
CLI command **qm** is your friend.  List/manipulate VMs and such with this utility.

==== Enable remote VNC login ability to ProxMox guests ====
Edit the file - **/etc/pve/local/qemu-server/<VMID>.conf**

Add **args: -vnc 0.0.0.0:77** to the end of the file (choose a unique number after the **:** for each guest)

A VNC connection to the guest is now possible by specifying the **host** IP address and the port chosen ("5977" in the example above).

==== Location of pertinent directories/files ====
ISOs get stored at **/var/lib/vz/template/iso**

===== ZFS Stuff =====

  zfs get mounted,mountpoint,canmount
  zfs list

==== Create a multi-disk zfs pool without RAID ====
  zpool create -o ashift=12 zpool /dev/sda /dev/sdb
