## virtualisierungsstack
|
|
|
|
|
|
|
|
## Ausbau-Varianten
|
|
|
|
### single node
|
|
|
|
- storage pool
|
|
- raid controller with lvm - ceph and zfs dont support raid controller - if raid controller used change to mode and use zfs
|
|
|
|
### Clustering ohne HA
|
|
|
|
- several storage pools
|
|
- pools not shared - individual
|
|
|
|
### zfs cluster with asynchron replication
|
|
|
|
- at least two pools
|
|
- in between quorum device which replicates the config between the nodes
|
|
|
|
### ceph cluster
|
|
|
|
- at least 3 nodes
|
|
- pool is combined and shared
|
|
|
|
## Installation
|
|
|
|
- its possible to provide custom toml files to install proxmox automatically
|
|
- zfs raid1 for boot drive
|
|
- define correct hostname; not so easy to change later
|
|
- modify update repos as first step! and update/upgrade the system
|
|
- hardware: always better to have as many interface ports as possible
|
|
- 2x 1 Gbit for mgmt
|
|
- 2x 10 Gbit for VMs (redundant, bond via LACP- \{needs stacked switches\} or backup-mode)
|
|
- 2x 25 Gbit for Ceph storage clustering
|
|
- single node at least 4 ports and for clustering at least 6 ports
|
|
- remove ip address of virtual bridge and set it directly on physical interface. Thus the VMs cant see the proxmox ip
|
|
- bond ports for VMs (ideally tow 10 Gbit ports) and setp virtual bridge on bond0 so that it can be used by VMs ( set 'VLAN aware' at bridge)
|
|
- its possible to create a bond for the web ui port
|
|
|
|
|
|
## VM creation
|
|
|
|
- id ranges can be configured in datacenter manager
|
|
- set tags at creation
|
|
- choosing guest os type properly as some features are directly set correctly; otherwise performance issues can arrise
|
|
- qemu agent recommended to install. improves snapshots and other stuff
|
|
- set at disk settings always: 'discard' and 'ssd emulation'. Otherwise ceph or other clustering solutions dont properly about changes on the disks
|
|
- best practice is to use virtio for storage and for network as it is the fastest
