3.8. Attaching a Storage Domain to a Data Center
This Ruby example attaches an existing NFS storage domain, mydata, to an existing data center, mydc. This example is used to attach both data and ISO storage domains.
Get the reference to the root of the services tree:
Locate the service that manages the storage domains and use it to
search for the storage domain:
Locate the service that manages the data centers and use it to
search for the data center:
Locate the service that manages the data center where you want to
attach the storage domain:
Locate the service that manages the storage domains that are attached
to the data centers:
Use the "add" method of service that manages the attached storage
domains to attach it:
Wait until the storage domain is active:
# Get the reference to the root of the services tree:
system_service = connection.system_service
# Locate the service that manages the storage domains and use it to
# search for the storage domain:
sds_service = system_service.storage_domains_service
sd = sds_service.list(search: 'name=mydata')[0]
# Locate the service that manages the data centers and use it to
# search for the data center:
dcs_service = system_service.data_centers_service
dc = dcs_service.list(search: 'name=mydc')[0]
# Locate the service that manages the data center where you want to
# attach the storage domain:
dc_service = dcs_service.data_center_service(dc.id)
# Locate the service that manages the storage domains that are attached
# to the data centers:
attached_sds_service = dc_service.storage_domains_service
# Use the "add" method of service that manages the attached storage
# domains to attach it:
attached_sds_service.add(
OvirtSDK4::StorageDomain.new(
id: sd.id
)
)
# Wait until the storage domain is active:
attached_sd_service = attached_sds_service.storage_domain_service(sd.id)
loop do
sleep(5)
sd = attached_sd_service.get
break if sd.status == OvirtSDK4::StorageDomainStatus::ACTIVE
end
