running

Maintenance should be performed only on the hosts in the reservation block which have running VMs.

unused

Maintenance should be performed only on the hosts in the reservation block which have no running VMs.

--zone=ZONE

Zone of the reservation to perform-maintenance. If not specified and the compute/zone property isn't set, you might be prompted to select a zone (interactive mode only).
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 be 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.
