None of the NetApp drivers declare support for multiattach yet, so I think this is expected behavior. Are we sure it's not supported here? I'm looking at the Liberty code for cinder and it seems like the eseries support multiattach but by default it's disabled and needs to be enabled? We are not supporting multi-attach as an OSP8 feature. |
Description of problem: Create a volume as multi-attach is failed with "No valid host was found. No weighed hosts available" using Netapp back-end Version-Release number of selected component (if applicable): python-cinder-7.0.1-5.el7ost.noarch openstack-cinder-7.0.1-5.el7ost.noarch python-cinderclient-1.4.0-1.el7ost.noarch How reproducible: 100% Steps to Reproduce: 1. Configure Netapp as back-end 2. Create a multi-attach volume Actual results: Creating a multi-attach volume is failed Expected results: Creating a multi-attach volume should succeed Additional info: [stack@instack ~]$ cinder create 1 --allow-multiattach --volume-type netapp1 [stack@instack ~]$ cinder show de99494c-8e5c-440a-83cc-ed43fd2a43a5 +---------------------------------------+--------------------------------------+ | Property | Value | +---------------------------------------+--------------------------------------+ | attachments | [] | | availability_zone | nova | | bootable | false | | consistencygroup_id | None | | created_at | 2016-02-14T07:50:03.000000 | | description | None | | encrypted | False | | id | de99494c-8e5c-440a-83cc-ed43fd2a43a5 | | metadata | {} | | migration_status | None | | multiattach | True | | name | None | | os-vol-host-attr:host | None | | os-vol-mig-status-attr:migstat | None | | os-vol-mig-status-attr:name_id | None | | os-vol-tenant-attr:tenant_id | 3a85e4a722e64171be1f495f3c47ccc8 | | os-volume-replication:driver_data | None | | os-volume-replication:extended_status | None | | replication_status | disabled | | size | 1 | | snapshot_id | None | | source_volid | None | | status | error | | user_id | 895a2cab60e449939bc1764458f305a3 | | volume_type | netapp1 | +---------------------------------------+--------------------------------------+ From scheduler log: 2016-02-11 09:45:43.669 2798 ERROR cinder.scheduler.flows.create_volume [req-cdd32b70-dc44-4d78-8b71-dbfb201ba3ae 895a2cab60e449939bc1764458f305a3 3a85e4a722e64171be1f495f3c47ccc8 - - -] Failed to run task cinder.scheduler.flows.create_volume.ScheduleCreateVolumeTask;volume:create: No valid host was found.
