gcloud beta compute instances detach-disk - detach disks from Compute Engine virtual machine instances

gcloud beta compute instances detach-diskINSTANCE_NAME(--device-name=DEVICE_NAME    |--disk=DISK)[--disk-scope=DISK_SCOPE; default="zonal"][--zone=ZONE][GCLOUD_WIDE_FLAG …]

Detaching a disk without first unmounting it may result in incomplete I/Ooperations and data corruption. To unmount a persistent disk on a Linux-basedimage, ssh into the instance and run:

sudoumount/dev/disk/by-id/google-DEVICE_NAME

gcloudbetacomputeinstancesdetach-diskmy-instance--disk=my-disk

To detach a device named 'my-device' from an instance named 'my-instance', run:

gcloudbetacomputeinstancesdetach-diskmy-instance--device-name=my-device

INSTANCE_NAME

Name of the instance to operate on. For details on valid instance names, referto the criteria documented under the field 'name' at:https://cloud.google.com/compute/docs/reference/rest/v1/instances

Exactly one of these must be specified:

--device-name=DEVICE_NAME

Specifies a disk to detach by its device name, which is the name that the guestoperating system sees. The device name is set at the time that the disk isattached to the instance, and needs not be the same as the persistent disk name.If the disk's device name is specified, then its persistent disk name must notbe specified using the--disk flag.

--disk=DISK

Specifies a disk to detach by its resource name. If you specify a disk to removeby persistent disk name, then you must not specify its device name using the--device-name flag.

--disk-scope=DISK_SCOPE; default="zonal"

The scope of the disk.DISK_SCOPE must be one of:

regional

The disk specified in --disk is interpreted as a regional disk in the sameregion as the instance. Ignored if a full URI is provided to the--disk flag.

zonal

The disk specified in --disk is interpreted as a zonal disk in the same zone asthe instance. Ignored if a full URI is provided to the--disk flag.

--zone=ZONE

Zone of the instance to operate on. If not specified, you might be prompted toselect a zone (interactive mode only).gcloud attempts to identify theappropriate zone by searching for resources in your currently active project. Ifthe zone cannot be determined,gcloud prompts you for a selection withall available Google Cloud Platform zones.

To avoid prompting when this flag is omitted, the user can set thecompute/zone property:

gcloudconfigsetcompute/zoneZONE

A list of zones can be fetched by running:

gcloudcomputezoneslist

To unset the property, run:

gcloudconfigunsetcompute/zone

Alternatively, the zone can be stored in the environment variableCLOUDSDK_COMPUTE_ZONE.
