Hi, Dilip Did your driver set the key pool_name and value when init_capabilities called in cinder volume init_host? If didn’t set the key pool_name and value, it will be none.

[cid:image001.png@01D15DD9.4533BCC0] Thanks Dilip From: Dilip Sunkum Manjunath [mailto:dilip.sunkummanjun...@toshiba-tsip.com] Sent: Tuesday, February 02, 2016 7:19 AM To: openstack@lists.openstack.org<mailto:openstack@lists.openstack.org> Cc: 'itzdi...@gmail.com' Subject: [Openstack] [CINDER] Scheduler Support for pools issue, not picking free pools Hi all, Use Case : Step 1 * I have multiple backend pools, * Updated the get_volume_stats() method to hold the pools information returned from storage API’s Sample log : [{'pool_name': '0', 'total_capacity_gb': 838, 'QoS_support': False, 'thick_provisioning_support': True, 'reserved_percentage': 1, 'consistencygroup_support': False, 'thin_provisioning_support': True, 'free_capacity_gb': 83.79999999999995}, {'pool_name': '1', 'total_capacity_gb': 1126, 'QoS_support': False, 'thick_provisioning_support': True, 'reserved_percentage': 1, 'consistencygroup_support': False, 'thin_provisioning_support': True, 'free_capacity_gb': 67.56000000000017}] Step 2 * In Create volume method am reading the pool information as storage api need pool info(on which pool in need to create) * Like pool_id = volume_utils.extract_host(volume['host'], level='pool') by making use of below import from cinder.volume import utils as volume_utils Problem am facing is: The scheduler is not always picking the free pool which has space, it returns the pool which don’t have space. I came to know when I printed the volume['host'] and above pool id. Is there anything else I must do? Please suggest.
