Attaching a disk to a VM

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

1. See the description of the CLI command for attaching disks:

   yc compute instance attach-disk --help
   

2. Get a list of VMs in the default folder:

   yc compute instance list
   

   Result:

   +----------------------+-----------------+---------------+---------+----------------------+
   |          ID          |       NAME      |    ZONE ID    | STATUS  |     DESCRIPTION      |
   +----------------------+-----------------+---------------+---------+----------------------+
   | fhm0b28lgfp4******** | first-instance  | ru-central1-a | RUNNING | my first vm via CLI  |
   | fhm9gk85nj7g******** | second-instance | ru-central1-a | RUNNING | my second vm via CLI |
   +----------------------+-----------------+---------------+---------+----------------------+
   

3. Select ID or NAME of the VM, e.g., first-instance.

4. Get a list of disks in the default folder:

   yc compute disk list
   

   Result:

   +----------------------+--------------+-------------+-------------------+--------+----------------------+-----------------+-------------+
   |          ID          |     NAME     |    SIZE     |       ZONE        | STATUS |     INSTANCE IDS     | PLACEMENT GROUP | DESCRIPTION |
   +----------------------+--------------+-------------+-------------------+--------+----------------------+-----------------+-------------+
   | a7lqgbt0bb9s******** | first-disk   | 20401094656 |   ru-central1-a   | READY  | a7lcvu28njbh******** |                 |             |
   | a7lv5j5hm1p1******** | second-disk  | 21474836480 |   ru-central1-a   | READY  |                      |                 |             |
   +----------------------+--------------+-------------+-------------------+--------+----------------------+-----------------+-------------+
   

5. Select ID or NAME of the disk, e.g., first-disk. To view a list of disks attached to the VM, run this command:

   yc compute instance get --full first-instance
   

6. Attach the disk to the VM:

   yc compute instance attach-disk first-instance \
     --disk-name first-disk \
     --mode rw
   

   To automatically delete the disk when deleting the VM, set the --auto-delete flag.

   Note

   Empty disks do not have a file system. If you are attaching an empty disk, partition and mount it manually. Alternatively, rather than attaching an empty disk, you can create a snapshot of the boot disk and use it to create a VM.

   If an error occurs, stop the VM:

   yc compute instance stop first-instance
   

   Then, try to attach the disk once again.

7. If the VM was stopped, restart it:

   yc compute instance start first-instance
   

With Terraform, you can quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. These files store the infrastructure description written in HashiCorp Configuration Language (HCL). If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

Terraform is distributed under the Business Source License. The Yandex Cloud provider for Terraform is distributed under the MPL-2.0 license.

For more information about the provider resources, see the relevant documentation on the Terraform website or its mirror.

If you do not have Terraform yet, install it and configure the Yandex Cloud provider.

1. In the configuration file, add the new secondary_disk section to the yandex_compute_instance resource description:

   resource "yandex_compute_instance" "vm-1" {
     ...
     secondary_disk {
         disk_id = "<disk_ID>"
     }
     ...
   }
   

   Where disk_id is the secondary disk ID.

   Note

   The secondary disk and VM must be in the same availability zone.

   For more information about yandex_compute_disk properties, see this Terraform article.

2. Apply the new configuration:

   1. In the terminal, go to the directory where you edited the configuration file.

   2. Make sure the configuration file is correct using this command:

      terraform validate
      

      If the configuration is correct, you will get this message:

      Success! The configuration is valid.
      

   3. Run this command:

      terraform plan
      

      You will see a detailed list of resources. No changes will be made at this step. If the configuration contains any errors, Terraform will show them.

   4. Apply the changes:

      terraform apply
      

   5. Type yes and press Enter to confirm the changes.

   Terraform will update all the required resources. You can check the update using the management console.

Use the attachDisk REST API method for the Instance resource or the InstanceService/AttachDisk gRPC API call.

1. Connect to the VM via RDP.

2. Run Computer Management (the compmgmt.msc snap-in) as an administrator.

3. Under Storage, select Disk Management.

   Note

   When you attach a disk to a running VM, it might not appear in the list. In that case, restart the OS and repeat the steps in this guide.

4. If the attached disk is Offline, right-click it and select Online.

5. Assign a drive letter to the attached disk, if required. To learn how to do this, see the relevant Microsoft documentation.

6. Open Explorer to check that the attached disk is properly mounted and available.

4. If the attached disk is Offline, right-click it and select Online.

5. Initialize the disk. To do this, right-click it and select Initialize Disk. This will open the Initialize Disk dialog box.

6. Select the partition style and click OK.

7. Create partitions on the disk. To do this, right-click an empty disk and select New Simple Volume.

8. Use the New Simple Volume Wizard to set the partition size, assign a drive letter, and specify the file system type.

9. Open Explorer to check that the attached disk is properly mounted and available.
