Recommeneded partitioning scheme:

Raid 1 (mirror) 40 000MB ext4 /
SWAP
- HDD less than 130gb = 16GB swap
- HDD more than 130GB and RAM less or equal to 64GB = 32GB swap
- HDD more than 130GB and RAM more than 64GB = 32GB swap
Remaining for lv ext4 /var/lib/vz (LVM)

Hetzner Proxmox Installation Guide

includes and runs the (install-post.sh) script

Select the Rescue tab for the specific server, via the hetzner robot manager
- Operating system=Linux
- Architecture=64 bit
- Public key=optional
--> Activate rescue system
Select the Reset tab for the specific server,
Check: Execute an automatic hardware reset
--> Send
Wait a few mins
Connect via ssh/terminal to the rescue system running on your server and run the following

wget https://raw.githubusercontent.com/extremeshok/xshok-proxmox/master/hetzner-install.sh -c -O install-hetzner.sh && chmod 777 hetzner-install.sh && ./install-hetzner.sh

Reboot
Connect via ssh/terminal to the new Proxmox system running on your server and run the following

wget https://raw.githubusercontent.com/extremeshok/xshok-proxmox/master/lvm2zfs.sh -c -O lvm2zfs.sh && bash lvm2zfs.sh && rm lvm2zfs.sh

Reboot
Post Install: Now login via ssh as root and create a password, which will be used for the webinterface when logging in with pam authentication

Disables the enterprise repo, enables the public repo
Adds non-free sources
Adds the latest ceph
Fixes known bugs (public key missing, max user watches, etc)

https://raw.githubusercontent.com/extremeshok/xshok-proxmox/master/install-post.sh

return value is 0

Or run install-post.sh after installation

wget https://raw.githubusercontent.com/extremeshok/xshok-proxmox/master/postinstall.sh -c -O postinstall.sh && bash postinstall.sh && rm postinstall.sh

Enable Docker support for an LXC container (pve-enable-lxc-docker.sh) optional

There can be security implications as the LXC container is running in a higher privileged mode.

curl https://raw.githubusercontent.com/extremeshok/xshok-proxmox/master/pve-enable-lxc-docker.sh --output /usr/sbin/pve-enable-lxc-docker && chmod +x /usr/sbin/pve-enable-lxc-docker
 pve-enable-lxc-docker container_id

Convert from LVM to ZFS (lvm2zfs.sh) run once

Converts the storage LVM into a ZFS raid 1 (mirror)

Uses the LVM with the path/mount of /var/lib/vz
Will automatically detect the required raid level and optimise
1 Drive = zfs (single)
2 Drives = mirror (raid1)
3-5 Drives = raidz-1 (raid5)
6-11 Drives = raidz-2 (raid6)
11+ Drives = raidz-3 (raid7)

NOTE: WILL DESTROY ALL DATA ON /var/lib/vz

wget https://raw.githubusercontent.com/extremeshok/xshok-proxmox/master/lvm2zfs.sh -c -O lvm2zfs.sh && bash lvm2zfs.sh && rm lvm2zfs.sh

Create ZFS from devices (createzfs.sh) optional

Creates a zfs pool from specified devices

Will automatically detect the required raid level and optimise
1 Drive = zfs (single)
2 Drives = mirror (raid1)
3-5 Drives = raidz-1 (raid5)
6-11 Drives = raidz-2 (raid6)
11+ Drives = raidz-3 (raid7)

NOTE: WILL DESTROY ALL DATA ON SPECIFIED DEVICES

wget https://raw.githubusercontent.com/extremeshok/xshok-proxmox/master/createzfs.sh -c -O createzfs.sh
bash createzfs.sh poolname /dev/device1 /dev/device2

Creates default routes to allow for extra ip ranges to be used (addiprange.sh) optional

If no interface is specified the default gateway interface will be detected and used.

wget https://raw.githubusercontent.com/extremeshok/xshok-proxmox/master/addiprange.sh -c -O addiprange.sh
bash addiprange.sh ip.xx.xx.xx/cidr interface_optional

Create Private mesh vpn/network (tincvpn.sh)

tinc private mesh vpn/network which supports multicast, ideal for private cluster communication

wget https://raw.githubusercontent.com/extremeshok/xshok-proxmox/master/tincvpn.sh -c -O tincvpn.sh && bash tincvpn.sh -h

Example for 3 node Cluster

First Host (hostname: host1)

bash tincvpn.sh -i 1 -c host2

Second Host (hostname: host2)

bash tincvpn.sh -i 2 -c host3

Third Host (hostname: host3)

bash tincvpn.sh -i 3 -c host1
