NO-System - Proxmox (pve) only for Hetzner

Install Proxmox Recommendations

Recommeneded partitioning scheme:

• Raid 1 (mirror) 40 000MB ext4 /
• Raid 1 (mirror) 30 000MB ext4 /xshok/zfs-cache only create if an ssd and there is 1+ unused hdd which will be made into a zfspool
• Raid 1 (mirror) 5 000MB ext4 /xshok/zfs-slog only create if an ssd and there is 1+ unused hdd which will be made into a zfspool
• SWAP
• • HDD less than 130gb = 16GB swap
• • HDD more than 130GB and RAM less than 64GB = 32GB swap
• • HDD more than 130GB and RAM more than 64GB = 64GB swap
• Remaining for lv xfs /var/lib/vz (LVM)

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

LVM to ZFS

wget https://raw.githubusercontent.com/CasCas2/xshok-proxmox/master/lvm-2-zfs.sh -c -O lvm-2-zfs.sh  && chmod +x lvm-2-zfs.sh
 ./lvm-2-zfs.sh && rm lvm-2-zfs.sh

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

Advance Installation Options

Assumptions: Proxmox installed, SSD raid1 partitions mounted as /xshok/zfs-slog and /xshok/zfs-cache, 1+ unused hdd which will be made into a zfspool

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

Create ZFS from unused devices (createzfs.sh)

NOTE: WILL DESTROY ALL DATA ON SPECIFIED DEVICES

wget https://raw.githubusercontent.com/CasCas2/xshok-proxmox/master/createzfs.sh -c -O createzfs.sh && chmod +x createzfs.sh
./createzfs.sh poolname /dev/device1 /dev/device2

Create ZFS cache and slog from /xshok/zfs-cache and /xshok/zfs-slog partitions and adds them to a zpool (xshok_slog_cache-2-zfs.sh) optional

NOTE: WILL DESTROY ALL DATA ON SPECIFIED PARTITIONS

wget https://raw.githubusercontent.com/CasCas2/xshok-proxmox/master/xshok_slog_cache-2-zfs.sh -c -O xshok_slog_cache-2-zfs.sh && chmod +x xshok_slog_cache-2-zfs.sh
./xshok_slog_cache-2-zfs.sh poolname

• Reboot

------- SCRIPTS ------

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/CasCas2/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 (lvm-2-zfs.sh) run once

Converts the a MDADM BASED LVM into a ZFS raid 1 (mirror)

• Defaults to mount point: /var/lib/vz
• Optional: specify the LVM_MOUNT_POINT ( ./lvm-2-zfs.sh LVM_MOUNT_POINT )
• Creates the following storage/rpools
• zfsbackup (rpool/backup)
• zfsvmdata (rpool/vmdata)
• /var/lib/vz/tmp_backup (rpool/tmp_backup)
• Will automatically detect the required raid level and optimise.
• 1 Drive = zfs
• 2 Drives = mirror
• 3-5 Drives = raidz-1
• 6-11 Drives = raidz-2
• 11+ Drives = raidz-3

NOTE: WILL DESTROY ALL DATA ON LVM_MOUNT_POINT

wget https://raw.githubusercontent.com/CasCas2/xshok-proxmox/master/lvm-2-zfs.sh -c -O lvm-2-zfs.sh && chmod +x lvm-2-zfs.sh
./lvm-2-zfs.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/CasCas2/xshok-proxmox/master/createzfs.sh -c -O createzfs.sh && chmod +x createzfs.sh
./createzfs.sh poolname /dev/device1 /dev/device2

Create ZFS cache and slog from /xshok/zfs-cache and /xshok/zfs-slog partitions and adds them to a zpool (xshok_slog_cache-2-zfs.sh) optional

Creates a zfs pool from specified devices

• Will automatically mirror the slog and stripe the cache if there are multiple drives

NOTE: WILL DESTROY ALL DATA ON SPECIFIED PARTITIONS

wget https://raw.githubusercontent.com/CasCas2/xshok-proxmox/master/xshok_slog_cache-2-zfs.sh -c -O xshok_slog_cache-2-zfs.sh && chmod +x xshok_slog_cache-2-zfs.sh
./xshok_slog_cache-2-zfs.sh poolname

CREATES A ROUTED vmbr0 AND NAT vmbr1 NETWORK CONFIGURATION FOR PROXMOX (network-configure.sh) run once

Autodetects the correct settings (interface, gatewat, netmask, etc) Supports IPv4 and IPv6, Private Network uses 10.10.10.1/24 Also installs and properly configures the isc-dhcp-server to allow for DHCP on the vmbr1 (NAT) ROUTED (vmbr0): All traffic is routed via the main IP address and uses the MAC address of the physical interface. VM's can have multiple IP addresses and they do NOT require a MAC to be set for the IP via service provider

NAT (vmbr1): Allows a VM to have internet connectivity without requiring its own IP address Assignes 10.10.10.100 - 10.10.10.200 via DHCP

Public IP's can be assigned via DHCP, adding a host define to the /etc/dhcp/hosts.public file

Tested on OVH and Hetzner based servers

ALSO CREATES A NAT Private Network as vmbr1

NOTE: WILL OVERWRITE /etc/network/interfaces A backup will be created as /etc/network/interfaces.timestamp

wget https://raw.githubusercontent.com/CasCas2/xshok-proxmox/master/network-configure.sh -c -O network-configure.sh && chmod +x network-configure.sh
./network-configure.sh && rm network-configure.sh

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

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

wget https://raw.githubusercontent.com/CasCas2/xshok-proxmox/master/network-addiprange.sh -c -O network-addiprange.sh && chmod +x network-addiprange.sh
./network-addiprange.sh ip.xx.xx.xx/cidr interface_optional

ZFS Snapshot Usage (Diabled for now)

# list all snapshots
zfs list -t snapshot
# create a pre-rollback snapshot
zfs-auto-snapshot --verbose --label=prerollback -r //
# rollback to a specific snapshot
zfs rollback <snapshotname>
