GCLOUD COMPUTE INSTANCES DETACH-DISK(1)


NAME

       gcloud_compute_instances_detach-disk - detach disks from Compute Engine
              virtual machine instances


SYNOPSIS

       gcloud compute instances detach-disk NAME [--device-name DEVICE_NAME |
              --disk DISK] [--format FORMAT] [--help] [--project PROJECT_ID]
              [--quiet, -q] [--zone ZONE] [-h]


DESCRIPTION

       gcloud compute instances detach-disk is used to detach disks from
       virtual machines.

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

           $ sudo umount /dev/disk/by-id/google-DEVICE_NAME


POSITIONAL ARGUMENTS

       NAME
           The name of the instance to detach the disk from.


FLAGS

       --device-name DEVICE_NAME
           Specifies a disk to detach by its device name, which is the name
           that the guest operating system sees. The device name is set at the
           time that the disk is attached 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 not be specified
           using the --disk flag.

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

       --zone ZONE
           The zone of the instance to detach a disk from. If not specified,
           you will be prompted to select a zone.

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

               $ gcloud config set compute/zone ZONE

           A list of zones can fetched by running:

               $ gcloud compute zones list

           To unset the property, run:

               $ gcloud config unset compute/zone

           Alternatively, the zone can be stored in the environment variable
           CLOUDSDK_COMPUTE_ZONE.

   GLOBAL FLAGS
       --format FORMAT
           Specify a format for printed output. By default, a command-specific
           human-friendly output format is used. Setting this flag to one of
           the available options will serialize the result of the command in
           the chosen format and print it to stdout. Supported formats are:
           json, text, yaml.

       --help
           Display detailed help.

       --project PROJECT_ID
           The Google Cloud Platform project name to use for this invocation.
           If omitted then the current project is assumed.

       --quiet, -q
           Disable all interactive prompts when running gcloud commands. If
           input is required, defaults will be used, or an error will be
           raised.

       -h
           Print a summary help and exit.


NOTES

       This command is in the Google Cloud SDK compute component. See
       installing components if it is not installed.
