Comprendre la fusion en direct dans la virtualisation RedHat (RHV)

La fusion en direct est une suppression d'instantané pendant que la machine virtuelle est en cours d'exécution. Une fusion en direct est lancée lorsqu'un utilisateur clique sur la commande "supprimer" associée à un instantané de disque pendant que la VM est en cours d'exécution. La fusion en direct est une opération asynchrone et le processus est assez complexe.

Voici le tableau du flux de fusion en direct des événements :

Moteur VDSM
Supprimer la commande d'instantané
RemoveSnapshotSingleDiskLiveCommand
MergeExtendCommand merge :cette opération est effectuée par le processus qemu en cours d'exécution et surveillée par libvirt
MergeVDSCommand getVolumeInfo
MergeStatusCommand Étendre le volume :Ceci est basé sur le format de volume (brut/vache) à étendre. L'extension de la taille ne peut s'exécuter que sur SPM.
DestroyImageCommand Synchronisation de la chaîne de volumes après la fusion en direct :mettez à jour les métadonnées de stockage d'une chaîne d'images après la fin d'une fusion en direct.
Tâches d'effacement/synchronisation SPM/HSM à partir des hôtes et de la base de données

Prenons l'exemple d'un instantané de laboratoire "test002" de suppression en direct. Vous verrez l'état de verrouillage lorsque l'opération est en cours dans la base de données du moteur et cette entrée d'instantané disparaîtra une fois la suppression de l'instantané terminée.
