To create a placement group for non-replicated disks:

Management console

CLI

API

In the management console, select the folder where you want to create a disk placement group.
Select Compute Cloud.
In the left-hand panel, select Placement groups.
Go to the Non-replicated disk placement groups tab.
In the top-right corner, click Create and select Non-replicated disk placement group.
Enter a name for the placement group. The naming requirements are as follows:
- It must be 2 to 63 characters long.
- It may contain lowercase Latin letters, numbers, and hyphens.
- It must start with a letter and cannot end with a hyphen.
Provide a description for the disk placement group, if required.
Specify the availability zone.
Select a placement strategy: spread or partition.

If you select the partition placement strategy, specify the number of partitions for non-replicated disks.
Click Create.

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

The folder specified in the CLI profile is used by default. You can specify a different folder through the --folder-name or --folder-id parameter.

See the description of the CLI command for creating a disk placement group:
```
yc compute disk-placement-group create --help
```
Create a disk placement group in the default folder with one of the following placement strategies:
- Spread placement:
```
yc compute disk-placement-group create \
  --name <disk_placement_group_name> \
  --zone <availability_zone> \
  --strategy SPREAD
```
  Where:
  - --name: Disk placement group name.
  - --zone: Availability zone.
  - --strategy: Placement strategy.
- Partition placement:
```
yc compute disk-placement-group create \
  --name <disk_placement_group_name> \
  --zone <availability_zone> \
  --strategy PARTITION \
  --partition-count <number_of_partitions>
```
  Where:
  - --name: Disk placement group name.
  - --zone: Availability zone.
  - --strategy: Placement strategy.
  - --partition-count: Number of partitions, two to five.

Get a list of disk placement groups in the default folder:

yc compute disk-placement-group list

Result:

+----------------------+---------------------+-------------------+--------+---------------+
|          ID          |        NAME         |       ZONE        | STATUS |   STRATEGY    |
+----------------------+---------------------+-------------------+--------+---------------+
| epd3oalmkmbp******** | drbasic-partition-1 | ru-central1-b | READY  | PARTITION [3] |
| epdn7r7co1v4******** | drbasic-spread-2    | ru-central1-b | READY  | SPREAD        |
+----------------------+---------------------+-------------------+--------+---------------+

Get information about the created disk placement group by specifying its name:

yc compute disk-placement-group get \
  --name <placement_group_name>

Result:

id: epd4sug6kesk********
folder_id: w3qrbj9swoty********
created_at: "2021-03-23T12:49:59Z"
name: first-group
zone_id: ru-central1-b
status: READY
spread_placement_strategy: {}

Use the create REST API method for the DiskPlacementGroup resource or the DiskPlacementGroupService/Create gRPC API call.
