Proxmox adding missing LVM thin Pool
When adding another node to the proxmox cluster and the LVM is missing it is not possible to add it correctly over the web interface. But here is how it works.
lsblk vgcreate pve /dev/sdc lvcreate -L 30G -n data pve lvconvert --type thin-pool pve/data
delete the VLM (just in case you need it)
lvchange -an /dev/data/data
reducing DNS packet size for nameserver to 1232
To solve this add a new file
/etc/dnsmasq.d/99-edns.conf
in this file add a single line:
edns-packet-max=1232
restart your DNS resolver
Vim: copy/cut paste without selecting line numbers
Let’s say I want to copy/cut lines 34 to 65. I use :34,65y (Copy/Yank) or :34,65d (Cut/Delete).
stuck at Install_SQLSupport_CPU64_Action

Install_SQLSupport_CPU64_Action,this happened to me for the second time, once at work and once at home.
The solution: You will need to browse to this installation path:

Install_SQLSupport_CPU64_Action run SQLSUPPORT.msiAnd follow the installation procedure.
Once installed, run the following command in cmd:
taskkill /F /FI "SERVICES eq msiserver"The SQL Server setup will continue and succeed.
