[SOLVED] Unable to Create rootdir Content in Volume ID for Container

[edsamodra]

Hello,

I am encountering an issue with content storage creation using the Proxmox API. Specifically, I am trying to create a subvolume format with rootdir content in my storage using the following API endpoint:

POST /api2/json/nodes/{node}/storage/{storage}/content

Here is the JSON parameter I used:

{
 "filename": "subvol-1007-disk-0",
 "node": "project-a",
 "size": "8G",
 "storage": "datastore",
 "vmid": 1007,
 "format": "subvol"
}

However, the content created is of type "images" instead of "rootdir". As we know, image content is intended for virtual machines, not containers. Could someone please assist me in understanding why this is happening and how to correctly create rootdir content?

Thank you in advance for your help.

A rootdir, as the name implies is the root volume for a container. It is usually created automatically when you create a container. The image you selected will be placed on this volume.

However, the naming is no different from a disk that was created for a VM.

The API you picked simply creates a new volume. It can be used for CT or VM. But to use it as a RootDir/RootFS you would need to specify it as a parameter in POST of https://pve.proxmox.com/pve-docs/api-viewer/#/nodes/{node}/lxc

Good luck.

Thank you! You're right.
My problem solve by this: Use the special syntax STORAGE_ID:SIZE_IN_GiB to allocate a new volume.
