[Openstack] 答复: [OpenStack] [CINDER] Scheduler Support for pools issue, not picking free pools
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.

主题: Re: [Openstack] [OpenStack] [CINDER] Scheduler Support for pools issue, not
picking free pools
Does it have anything to do with capabilities option?
Pool_name seems to be none.

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': 83.75}, {'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': 67.560017}]
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.
Thanks
Dilip

Any chance you can share a link to either a patch in gerrit or the code on
Github?
