Re: [Openstack] [OpenStack] [CINDER] how to get updated pool info when multi users create volumes on pool configured?
Hi Xing, Thanks for replay, I tried because the use case was to support both in single pool. I was thinking in same as to read the volume type in scheduler, however since it is a new requirement that affects everyone it might not be good to change now. I shall try with the other approach pools for thin /thick and update you.

Hi Dilip, I see. If thin_provisioning is true and max_over_subscription_ratio is valid, the scheduler will treat it as thin provisioning. We do not prevent driver from reporting both thin and thick support to be true. However, I think we need to make a change. I suggest that you have one pool for thin and the other one for thick but don't report both thin and thick support from the same pool. That will avoid this problem. Another possible alternative is to require thin/thick provisioning to be in extra specs and use that info in the scheduler, however that will be a new requirement that affects everyone. So I am not in favor of that approach. Can you use one pool for thin and another for thick in your testing?

Hi Dilip,
Can you please clarify your question? If a driver reports both
thin_provisioning and thick_provisioning to True and reports free_capacity
based on thin provisioning , and you want to provision a thick volume, the
scheduler won’t block it and it fail when the driver tries to create volume?
If you can describe the exact problem, we can try to find a solution.
Thanks,

Hi all,
The problem what I noticed is, in update stats we send thick and thin volume
support as true. This issue can be reproduced.
So the over provision and thick and thin parameters are reason, scheduler is
not blocking for thick volume based on the capacity if it is thick, it Is
passing to the driver which forces driver to handle a particular use case!!
I believe this has to handle at the above layer, however it will not know what
kind of volume is created using volume types, I think this also has to be
considered in scheduler!
Any one has a better approach? For this or is it better to write own filters to
avoid writing in driver?
Thanks

Hi, Dilip
Generally, Cinder scheduler will consume the free_capacity_gb after chose the
host for a volume creation, could see the consume_from_volume function in
host_manager.py.
That keep the pool capacity gb updated correctly when multi users are creating
volume.

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.
