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 → Non-replicated disk placement group.
Enter a name for the placement group. The naming requirements are as follows:
- The name must be from 3 to 63 characters long.
- It may contain lowercase Latin letters, numbers, and hyphens.
- The first character must be a letter and the last character cannot be a hyphen.
If required, add a group description.
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 command line interface yet, install and initialize it.

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

View the description of the CLI command to create a disk placement group:
```
yc compute disk-placement-group create --help
```
Create a placement group in the default folder with one of the 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 your 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: {}
