Configura la replica asincrona dei dischi permanenti

Questo documento descrive come configurare la replica asincrona. La replica asincrona è utile per il ripristino di emergenza con RPO e RTO bassi.

Per abilitare la replica asincrona dei dischi, completa i seguenti passaggi:

  1. Configura una coppia di replica dei dischi per configurare la replica asincrona.
  2. Avvia manualmente la replica per iniziare a replicare i dati tra il disco primario e quello secondario.

Limitazioni

  • I dischi secondari devono essere vuoti al momento della creazione. Non possono essere creati da immagini, snapshot o altri dischi.
  • La replica asincrona non è supportata per Hyperdisk ML o Hyperdisk Throughput.
  • Non puoi configurare la replica asincrona per Hyperdisk nella console Google Cloud . Devi utilizzare Google Cloud CLI, Terraform o REST.

Prima di iniziare

Configurare una coppia di replica del disco

Prima di poter replicare i dati tra i dischi, devi configurare la replica completando le seguenti attività:

  1. Scegli una coppia di regioni e le regioni principale e secondaria.
  2. (Facoltativo) Se devi coordinare la replica in un gruppo di dischi, crea un gruppo di coerenza nella regione primaria. Devi aggiungere dischi primari a un gruppo di coerenza prima di avviare la replica.
  3. Crea o seleziona i dischi principali. Se vuoi, puoi aggiungere questi dischi al gruppo di coerenza.
  4. Crea dischi secondari vuoti.

Requisiti del disco

I dischi devono soddisfare i seguenti requisiti per essere utilizzati come dischi primari o secondari per la replica asincrona:

  • Tipo di disco: devi utilizzare uno dei seguenti tipi di disco:
    • Disco permanente bilanciato
    • Disco permanente (SSD) prestazionale
    • Hyperdisk bilanciato
    • Hyperdisk bilanciato con disponibilità elevata
    • Hyperdisk Extreme
  • Dimensioni: inferiore o uguale a 64 TiB.
  • Tipo di crittografia: Google-owned and Google-managed encryption keys o chiavi di crittografia gestite dal cliente (CMEK).
  • Modalità multi-writer: puoi attivare la replica asincrona per i dischi Hyperdisk bilanciato e Hyperdisk bilanciato ad alta affidabilità in modalità multi-writer. Per tutti gli altri tipi di dischi, il disco deve essere in modalità di lettura e scrittura.
  • Località: si trova in una regione supportata (o in una zona all'interno di una regione supportata).

Crea o seleziona un disco primario

Il disco principale è il disco di avvio o di dati collegato alla VM in cui viene eseguito il workload. Puoi utilizzare qualsiasi disco preesistente che soddisfi i requisiti del disco come disco primario oppure puoi creare un nuovo disco. Se vuoi utilizzare un disco esistente come disco primario, non devi eseguire alcuna configurazione aggiuntiva sul disco. Vai a creare un disco secondario per completare la configurazione della replica asincrona.

Crea un disco primario

Crea un disco primario utilizzando i metodi descritti in uno dei seguenti documenti.

  • Crea un disco di avvio principale durante la creazione di una VM. (Facoltativo) Aggiungi il disco a un gruppo di coerenza creando la VM utilizzando gcloud CLI o REST e specificando uno dei seguenti elementi:

    • Se crei la VM utilizzando gcloud CLI, specifica il flag --create-disk:

      --create-disk=disk-resource-policy=projects/PROJECT/regions/REGION/resourcePolicies/CONSISTENCY_GROUP_NAME

    • Se crei la VM utilizzando REST, specifica la proprietà resourcePolicies:

      "disks":
{
…
"resourcePolicies": "projects/PROJECT/regions/REGION/resourcePolicies/CONSISTENCY_GROUP_NAME"
}

  • Crea un disco dati principale durante la creazione di una VM. (Facoltativo) Aggiungi il disco a un gruppo di coerenza creando la VM utilizzando gcloud CLI o REST e specificando uno dei seguenti elementi:

    • Se crei la VM utilizzando gcloud CLI, specifica il flag --create-disk:

      --create-disk=disk-resource-policy=projects/PROJECT/regions/REGION/resourcePolicies/CONSISTENCY_GROUP_NAME

    • Se crei la VM utilizzando REST, specifica la proprietà resourcePolicies:

      "disks":
{
…
"resourcePolicies": "projects/PROJECT/regions/REGION/resourcePolicies/CONSISTENCY_GROUP_NAME"
}

  • Crea un disco dati principale senza creare una VM. Se vuoi, aggiungi il disco a un gruppo di coerenza creando la VM utilizzando la consoleGoogle Cloud , gcloud CLI o REST e specificando uno dei seguenti elementi:

    • Se crei il disco utilizzando la console Google Cloud , seleziona il gruppo di coerenza dal menu a discesa Gruppo di coerenza.

    • Se crei il disco utilizzando gcloud CLI, specifica il flag --resource-policies:

      --resource-policies=projects/PROJECT/regions/REGION/resourcePolicies/CONSISTENCY_GROUP_NAME

    • Se crei il disco utilizzando REST, specifica la proprietà resourcePolicies:

      "disks":
{
…
"resourcePolicies": "projects/PROJECT/regions/REGION/resourcePolicies/CONSISTENCY_GROUP_NAME"
}

    Sostituisci quanto segue:

    • PROJECT: il progetto che contiene il gruppo di coerenza
    • REGION: la regione in cui si trova il gruppo di coerenza
    • CONSISTENCY_GROUP_NAME: il nome del gruppo di coerenza a cui aggiungere il disco

Crea un disco secondario

Il disco secondario è un disco di dati in una regione separata dal disco principale, che riceve e scrive i dati replicati dal disco principale. Quando configuri la replica asincrona, devi creare un nuovo disco secondario vuoto che faccia riferimento al disco primario.

Per creare un disco secondario con le stesse proprietà del disco primario, segui i passaggi descritti in Creare un disco secondario identico al disco primario.

Per creare un disco secondario diverso dal disco primario, consulta Creare un disco secondario personalizzato.

Crea un disco secondario identico al disco primario

Questa sezione descrive come creare un disco secondario identico al disco primario.

  • Per la replica asincrona di Persistent Disk, puoi creare un disco secondario con la consoleGoogle Cloud , gcloud CLI o REST.

  • Per la replica asincrona Hyperdisk, puoi utilizzare gcloud CLI, Terraform o REST.

Console

Crea un disco secondario e avvia la replica nel seguente modo:

  1. Nella console Google Cloud vai alla pagina Dischi.

    Vai a Dischi

  2. Fai clic sul nome del disco principale. Viene visualizzata la pagina Gestisci disco.

  3. Fai clic su Crea disco secondario.

  4. Nel campo Nome, inserisci un nome per il disco.

  5. Nella sezione Località, esegui una delle seguenti operazioni:

  6. Fai clic su Crea. Compute Engine crea il disco e avvia la replica.

gcloud

Crea un disco secondario utilizzando il comando gcloud compute disks create:

gcloud compute disks create SECONDARY_DISK_NAME \
    --SECONDARY_LOCATION_FLAG=SECONDARY_LOCATION \
    --size=SIZE \
    --primary-disk=PRIMARY_DISK_NAME \
    --PRIMARY_DISK_LOCATION_FLAG=PRIMARY_LOCATION \
    --primary-disk-project=PRIMARY_DISK_PROJECT

Per creare un disco secondario regionale, specifica anche il flag --replica-zones:

--replica-zones=ZONE_1,ZONE_2

Sostituisci quanto segue:

  • SECONDARY_DISK_NAME: il nome del disco secondario.
  • SECONDARY_LOCATION_FLAG: il flag di posizione del disco secondario. Per creare un disco secondario a livello di regione, utilizza --region. Per creare un disco secondario a livello di zona, utilizza --zone.
  • SECONDARY_LOCATION: la regione o la zona del disco secondario.
  • SIZE: le dimensioni, in GB, del nuovo disco. La dimensione deve essere uguale a quella del disco primario. Le dimensioni consentite vanno da 10 GB a 2000 GB, con incrementi di 1 GB.
  • PRIMARY_DISK_NAME: il nome del disco primario da cui il disco secondario riceve i dati.
  • PRIMARY_LOCATION_FLAG: il flag di posizione del disco principale.
    • Per un disco primario a livello di regione, utilizza --primary-disk-region.
    • Per un disco primario a livello di zona, utilizza --primary-disk-zone.
  • PRIMARY_LOCATION: la regione o la zona del disco primario.
    • Per un disco a livello di regione, utilizza la regione.
    • Per i dischi a livello di zona, utilizza la zona.
  • PRIMARY_PROJECT: il progetto che contiene il disco primario.
  • ZONE_1: una delle zone in cui viene replicato il disco regionale. Deve essere una zona all'interno della regione specificata e deve essere diversa da ZONE_2.
  • ZONE_2: una delle zone in cui viene replicato il disco regionale. Deve essere una zona all'interno della regione specificata e deve essere diversa da ZONE_1.

REST

Crea un disco secondario zonale o regionale utilizzando uno dei seguenti metodi:

  • Per creare un disco secondario a livello di zona, utilizza il metodo disks.insert:

    POST https://compute.googleapis.com/compute/v1/projects/SECONDARY_DISK_PROJECT/zones/SECONDARY_DISK_LOCATION/disks

{
"name": "SECONDARY_DISK_NAME",
"sizeGb": "DISK_SIZE",
"type": "DISK_TYPE"
"asyncPrimaryDisk": {
  "disk": "projects/PRIMARY_DISK_PROJECT/PRIMARY_DISK_LOCATION_PARAMETER/PRIMARY_DISK_LOCATION/disks/PRIMARY_DISK_NAME"
  }
}

  • Per creare un disco secondario regionale, utilizza il metodo regionDisks.insert:

    POST https://compute.googleapis.com/compute/v1/projects/SECONDARY_DISK_PROJECT/regions/SECONDARY_DISK_LOCATION/disks

{
"name": "SECONDARY_DISK_NAME",
"sizeGb": "DISK_SIZE",
"type": "DISK_TYPE"
"asyncPrimaryDisk": {
  "disk": "projects/PRIMARY_DISK_PROJECT/PRIMARY_DISK_LOCATION_PARAMETER/PRIMARY_DISK_LOCATION/disks/PRIMARY_DISK_NAME"
  }
}

Sostituisci quanto segue:

  • SECONDARY_DISK_PROJECT: il progetto per il disco secondario.
  • SECONDARY_DISK_LOCATION: la regione o la zona per il disco secondario.
    • Per un disco a livello di regione, utilizza la regione.
    • Per un disco a livello di zona, utilizza la zona.
  • SECONDARY_DISK_NAME: il nome del disco secondario.
  • DISK_SIZE: le dimensioni del disco secondario. Deve essere uguale alla dimensione del disco primario.
  • PRIMARY_DISK_PROJECT: il progetto che contiene il disco primario.
  • PRIMARY_DISK_LOCATION_PARAMETER: il parametro di posizione per il disco primario.
    • Per un disco primario a livello di regione, utilizza regions.
    • Per un disco primario a livello di zona, utilizza zones.
  • PRIMARY_DISK_LOCATION: la regione o la zona del disco primario. Per i dischi a livello di regione, utilizza la regione. Per i dischi a livello di zona, utilizza la zona.
  • PRIMARY_DISK_NAME: il nome del disco primario da cui il disco secondario riceve i dati.

Terraform

Per creare un disco secondario identico al disco primario, utilizza la risorsa compute_disk.

resource "google_compute_disk" "secondary_disk" {
  name = "secondary-disk"
  type = "pd-ssd"
  zone = "europe-west3-a"

  async_primary_disk {
    disk = google_compute_disk.primary_disk.id
  }

  physical_block_size_bytes = 4096
}

Per scoprire come applicare o rimuovere una configurazione Terraform, consulta Comandi Terraform di base.

Crea un disco secondario personalizzato

Questa sezione descrive come creare un disco secondario personalizzato, ovvero un disco secondario le cui proprietà differiscono da quelle del disco primario.

Se il disco primario è un disco di avvio, non puoi modificare o rimuovere nessuna delle funzionalità del sistema operativo guest del disco primario. Puoi aggiungere solo altre funzionalità del sistema operativo guest. Per maggiori informazioni, consulta Personalizzazione del disco secondario.

Puoi creare un disco secondario personalizzato con gcloud CLI, REST o Terraform. Non puoi personalizzare il disco secondario dalla console Google Cloud .

gcloud

Per creare un disco secondario personalizzato, utilizza il comando gcloud compute disks create come descritto in Crea un disco secondario identico al disco primario. Utilizza flag aggiuntivi per personalizzare le proprietà del disco secondario.

Di seguito sono riportati alcuni esempi di come personalizzare il disco secondario:

  • Per specificare funzionalità aggiuntive del sistema operativo guest, utilizza il parametro --guest-os-features.

     --guest-os-features=UEFI_COMPATIBLE,GVNIC,MULTI_IP_SUBNET

  • Per assegnare etichette aggiuntive al disco secondario, utilizza il parametro --labels. 
      --labels=secondary-disk-for-replication=yes

Per creare un disco secondario personalizzato, utilizza lo stesso metodo descritto in Crea un disco secondario identico al disco primario. Specifica campi aggiuntivi per personalizzare le proprietà del disco secondario.

Di seguito sono riportati alcuni esempi di come personalizzare il disco secondario:

  • Per specificare funzionalità aggiuntive del sistema operativo guest, utilizza il campo guestOsFeatures. Puoi specificare solo funzionalità aggiuntive del sistema operativo guest. Non puoi modificare o rimuovere nessuna delle funzionalità del sistema operativo guest copiate dal disco primario. 
    "guestOsFeatures": [
  {
    "type": "NEW_FEATURE_ID_1"
  },
  {
    "type": "NEW_FEATURE_ID_1"
  }
]
  • Per assegnare etichette aggiuntive al disco secondario, utilizza il campo labels. 
      "labels": [
    {
      "key": "value"
    },
  ]

      labels = {
    environment = "dev"
  }

Avvia replica

Dopo aver creato un disco primario e uno secondario, devi avviare la replica per iniziare a replicare i dati dal disco primario al disco secondario.
