 ====== 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.
-=== Package updates fail after ProxMox install ===
+==== Enable remote VNC login ability to ProxMox guests ====
-The automatic package update script will fail, because ProxMox “assumes” you will have a subscription (silly ProxMox).  To fix this, the process must run at least once (and fail) and then it can be flipped to the “no-subscription repository” as follows…
-  Select “Repositories” underneath “Updates”
-  Disable the ceph-quincy and pve repositories
-  Click “Add”
-  In the Repository drop-down box, select “No-Subscription” and click Add.
-=== Enable remote VNC login ability to ProxMox guests ===
 Edit the file - **/etc/pve/local/qemu-server/<VMID>.conf**
@@ Line 17: / Line 33: @@
 A VNC connection to the guest is now possible by specifying the **host** IP address and the port chosen ("5977" in the example above).
-=== Syslog not installed by default ===
+==== Location of pertinent directories/files ====
-To install:
+ISOs get stored at **/var/lib/vz/template/iso**
-  apt install -y rsyslog
-=== Disable/remove the annoying "no subscription" message that pops during login ===
-<color red>**As of 8.4.5, this no longer works; currently researching alternatives** - https://free-pmx.pages.dev/tools/free-pmx-no-subscription/ might be one.</color>
-Login to the ProxMox node via ssh and run the following code:
+===== ZFS Stuff =====
-  sed -Ezi.bak "s/(function\(orig_cmd\) \{)/\1\n\torig_cmd\(\);\n\treturn;/g" /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js && systemctl restart pveproxy.service
-If/when the proxmox-widget-toolkit package gets updated, this command will need to be run again.
+  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
