|
|
*{command}* moves a Compute Engine virtual machine
|
|
from one zone to another. Moving a virtual machine might incur downtime
|
|
if the guest OS must be shut down in order to quiesce disk volumes
|
|
prior to snapshotting.
|
|
|
|
For example, running the following command moves the instance
|
|
called `example-instance-1` with its attached persistent disks,
|
|
currently running in `us-central1-b`, to `us-central1-f`.
|
|
|
|
$ gcloud compute instances move example-instance-1 --zone=us-central1-b --destination-zone=us-central1-f
|
|
|
|
Note: Moving VMs or disks by using the `{command}` command might
|
|
cause unexpected behavior. For more information, see https://cloud.google.com/compute/docs/troubleshooting/known-issues#moving_vms_or_disks_using_the_moveinstance_api_or_the_causes_unexpected_behavior.
|
|
|
|
Please note that gcloud compute instances move does not yet support
|
|
instances which have regional persistent disks attached. Please see
|
|
https://cloud.google.com/compute/docs/disks/regional-persistent-disk for
|
|
more details.
