Fence agents

Primary LanguageMakefile

This work was done for a client who finally did not pay me one cent for it ( http://e-conception.fr ), so if you do have a chance do the same to them don't think twice about it.

Installation du module 'fencing' pour online sur proxmox a partir des sources

BIG FAT WARNING

this is a bad idea!

you need at least three machines, and so the drbd and fencing config will need adaptation

remplacer

  • YOUR_ONLINE_API_KEY par le token privé obtenu de https://console.online.net/fr/api/access
  • OTHER indique toujours la machine qui est pas utilisé pour la construction
  • YOURMACHINEIP OTHERMACHINEIP par les adresses ip des machines
  • ONLINE_ID OTHER_ONLINE_ID par les identifiants online des serveurs (seul les chiffres, sans le préfix sd-)
  • MACHINEHOSTNAME OTHER_MACHINEHOSTNAME le nom d'hote des machines, défault est sd-ONLINE_ID par online
  • IncrementPreviousValue en incrémentant la valeur précédente

ajouter dans le fichier /etc/default/redhat-cluster-pve sur les deux machines:

FENCE_JOIN="yes"

Sur l'interface proxmox

  • Vue Datacenter
  • dans l'onglet HA
  • activer la nouvelle configuration (bouton 'Activate')

Pour activer la gestion Haute Disponibilité pour une machine virtuelle existante

  • Vue Datacenter
  • dans l'onglet HA
  • bouton add
  • HA managed VM/CT
  • mettre l'id numérique de la VM souhaité
  • clicker activate pour activer la nouvelle configuration cluster
