Re: [Engine-devel] Fwd: storagedomain status via API
Hi Ryan, SD status available only in datacenter context [1], as some of domains may be shared between datacenters, i.e: dc = api.datacenters.get(name="xxx") sd = dc.storagedomains.get(name="images-cluster1") sd.status [1] except of 'unatached' domains. On 08/27/2012 05:11 PM, Itamar Heim wrote:

Should all created storage domains have 'status' in the API? Below, I've got one active NFS data domain, and a second ISO domain defined, but not activated. the <status> element is only available for the the ISO domain.
I'd really like a way to enumerate the storage domains, and check whether a domain is OK or not.
via python shell ovirt-sdk:
iso = api.storagedomains.get(name='isos-20120614') iso.name 'isos-20120614' iso.status.state 'unattached' sd = api.storagedomains.get(name='images-cluster1') sd.name 'images-cluster1' sd.status.state Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'NoneType' object has no attribute 'state'

Hi Ryan,
He Michael,
SD status available only in datacenter context [1], as some of domains may be shared between datacenters, i.e:
dc = api.datacenters.get(name="xxx") sd = dc.storagedomains.get(name="images-cluster1") sd.status
[1] except of 'unatached' domains.
Right, this does make checking the state/status of a storage domain programtically troublesome. I can get a list of all storagedomains, but only some of them will have. the 'status' attribute. If it doesn't have the status attribute, then I need to enumerate all of the datacenters, and for each datacenter, I can list the storage domains, and check the status there. Any reason the status of each storagedomain can't be present under api/storagedomains? Also, any tips on deleting 'unattached' domains via the python bindings?

storagedomain can be shared between different datacenters, i.e it may have status X in DC1 and Y in DC2, so only use-case for SD to have status outside of DC context, is when it not attached yet.
Also, any tips on deleting 'unattached' domains via the python bindings?

OK, that makes sense.
