Choices:

  • false

  • true

size

string

Desired volume size in GB to allocate when state=present (specify size without suffix).

New (or additional) size of volume when state=resized. With the + sign the value is added to the actual size of the volume and without it, the value is taken as an absolute one.

Choices:

  • false

state

string

Indicates desired state of the disk.

state=present can be used to create, replace disk or update options in existing disk. It will create missing disk or update options in existing one by default. See the create parameter description to control behavior of this option.

Some updates on options (like cache) are not being applied instantly and require VM restart.

Use state=detached to detach existing disk from VM but do not remove it entirely. When state=detached and disk is unused[n] it will be left in same state (not removed).

state=moved may be used to change backing storage for the disk in bounds of the same VM or to send the disk to another VM (using the same backing storage).

state=resized intended to change the disk size. As of Proxmox 7.2 you can only increase the disk size because shrinking disks is not supported by the PVE API and has to be done manually.

To entirely remove the disk from backing storage use state=absent.

Choices:

  • "present" ← (default)

  • "resized"

  • "detached"

  • "moved"

  • "absent"

storage

string

The drive’s backing storage.

Used only when state is present.

target_disk

string

The config key the disk will be moved to on the target VM (for example, ide0 or scsi1).

Default is the source disk key.

Used only when state=moved.

target_storage

string

Move the disk to this storage when state=moved.

You can move between storages only in scope of one VM.

Mutually exclusive with target_vmid.

Consider increasing timeout in case of large disk images or slow storage backend.

target_vmid

integer

The (unique) ID of the VM where disk will be placed when state=moved.

You can move disk between VMs only when the same storage is used.

Mutually exclusive with target_vmid.

timeout

integer

Timeout in seconds to wait for slow operations such as importing disk or moving disk between storages.

Used only when state is present or moved.

Default: 600

trans

string

Force disk geometry bios translation mode.

Choices:

  • "auto"

  • "lba"

  • "none"

validate_certs

boolean

If false, SSL certificates will not be validated.

This should only be used on personally controlled sites using self-signed certificates.

Choices:

  • false ← (default)

  • true

vmid

integer

The unique ID of the VM.

You can specify either vmid or name or both of them.

werror

string

Write error action.

Choices:

  • "enospc"

  • "ignore"

  • "report"

  • "stop"

wwn

string

The drive’s worldwide name, encoded as 16 bytes hex string, prefixed by 0x.
