Ce document explique comment redimensionner et cloner des disques de réplication asynchrone.
Artifact Registry est utile pour la reprise après sinistre à faibles RPO et RTO. Pour en savoir plus sur la réplication asynchrone, consultez À propos de la réplication asynchrone.
Limites
Le disque principal et le disque secondaire doivent avoir la même taille. Si vous redimensionnez un disque principal qui est en réplication active, le disque secondaire est automatiquement redimensionné. Si le disque secondaire ne peut pas être redimensionné automatiquement, vous devez le redimensionner manuellement pour qu'il fasse la même taille que le disque principal. La réplication est suspendue jusqu'à ce que le disque secondaire fasse la même taille que le disque principal.
Vous ne pouvez pas cloner des disques principaux à partir d'un groupe de cohérence. Vous devez cloner les disques principaux individuellement. Toutefois, vous pouvez cloner des disques secondaires à partir d'un groupe de cohérence.
Si ce n'est pas déjà fait, configurez l'authentification.
L'authentification est le processus permettant de valider votre identité pour accéder aux services et aux API Google Cloud .
Pour exécuter du code ou des exemples depuis un environnement de développement local, vous pouvez vous authentifier auprès de Compute Engine en sélectionnant l'une des options suivantes :
Select the tab for how you plan to use the samples on this page:
Console
When you use the Google Cloud console to access Google Cloud services and
APIs, you don't need to set up authentication.
gcloud
Installez Google Cloud CLI.
Après l'installation,
initialisez Google Cloud CLI en exécutant la commande suivante :
Pour utiliser les exemples d'API REST de cette page dans un environnement de développement local, vous devez utiliser les identifiants que vous fournissez à gcloud CLI.
Installez Google Cloud CLI.
Après l'installation,
initialisez Google Cloud CLI en exécutant la commande suivante :
Pour en savoir plus, consultez la section S'authentifier pour utiliser REST dans la documentation sur l'authentification Google Cloud .
Redimensionner des disques
Si vous avez besoin d'espace de stockage supplémentaire ou de limites de performances accrues, vous pouvez augmenter la taille d'un disque principal jusqu'à 64 Tio.
Vous ne pouvez pas réduire la taille d'un disque.
Lorsque vous redimensionnez un disque principal qui réplique activement un disque secondaire, la taille de ce disque est augmentée pour atteindre la même taille que celle du disque principal.
Si le disque secondaire ne peut pas être redimensionné automatiquement, vous devez le redimensionner manuellement pour qu'il fasse la même taille que le disque principal.
CONSISTENCY_GROUP : URL du groupe de cohérence contenant les disques secondaires à cloner. Exemple : projects/PROJECT/regions/REGION/resourcePolicies/CONSISTENCY_GROUP_NAME.
LOCATION_FLAG : option d'emplacement pour les disques du groupe de cohérence. Pour les disques régionaux, utilisez --region. Pour les disques zonaux, utilisez --zone.
LOCATION : région ou zone dans laquelle se trouvent les disques du groupe de cohérence. Pour les disques régionaux, utilisez la région. Pour les disques zonaux, utilisez la zone. Les clones sont créés à cet emplacement.
REST
Clonez tous les disques secondaires dans un groupe de cohérence à l'aide de l'une des méthodes suivantes :
Pour cloner des disques zonaux dans un groupe de cohérence, utilisez la méthode disks.bulkInsert :
POST https://compute.googleapis.com/compute/v1/projects/CLONE_PROJECT/zones/ZONE/disks/bulkInsert

If you resize a primary disk that is actively replicating, then the secondary disk is automatically resized. If the secondary disk fails to resize automatically, then you must manually resize it to the same size as the primary disk. Replication is paused until the secondary disk is the same size as the primary disk.\n- You can't clone primary disks from a consistency group. You must clone primary disks individually. However, you can clone secondary disks from a consistency group.\n\nBefore you begin\n----------------\n\n- [Create a primary disk](/compute/docs/disks/async-pd/configure#create_a_primary_disk).\n- [Create a secondary disk](/compute/docs/disks/async-pd/configure#create_a_secondary_disk).\n- If you haven't already, set up [authentication](/compute/docs/authentication).
