Integrate volumedriver fencing #970

Closed khenderick closed 7 years ago

khenderick commented 7 years ago

Integrate volumedriver fencing: https://github.com/openvstorage/volumedriver/pull/120

khenderick commented 7 years ago

Remark: check for compatible alba version to be integrated at the same time.

khenderick commented 7 years ago

We can only enable this flag when used with an Alba backend.

khenderick commented 7 years ago

Fixed by #996, packaged in openvstorage-2.7.4-rev.4084.68cc098

JeffreyDevloo commented 7 years ago

Information

The change in framework introduced a new parameter 'vrouter_use_fencing' in the volumedriver config. This parameter should default to 'false' by the volumedriver but framework will configure it to 'true' by default.

Code wise

sdc = StorageDriverConfiguration('storagedriver', vdisk.vpool_guid, vdisk.storagedriver_id)
sdc.load()
if 'vrouter_use_fencing' in sdc.configuration.get('volume_router'):
    print 'Parameter in config'
    if sdc.configuration.get('volume_router')['vrouter_use_fencing'] is True:
        print 'Parameter set to the default value'

Code above gives:

Parameter in config
Parameter set to the default value

Test result

Test passed.
