Description Kesavan 2021-12-17 07:57:42 UTC

Today, we can apply quota to individual subvolume. However when working on a multi-tenant environment, the storage admin wants to provision quota for a given subvolumegroup, so one level above the subvolume.
It will be nice if we could set a desired quota per subvolumegroup.

Hi Kotresh,

The workflow you describe is correct.

The deletion of the subvolumegroup will only happen on cluster uninstallation and the controller will block if Subvolumes still exists.
Can you elaborate on the subvolumegroup deletion behavior and why an immediate deletion could be an issue?

Thanks.

Thanks Sebastien and Orit for the answers. Reply inline.

When a subvolume is deleted, it is moved to trash directory and the call is
returned to user with success. The actual deletion happens asynchronously.
The trash directory of the subvolumes has to reside inside subvolumegroup if quota
is enabled because of [1]. If the subvolumegroup deletion is received immediately after
subvolumes deletion, the caller would receive 'EAGAIN' until the trash directory is empty.
So I think this behavior is fine ?

If the deletion fails with EAGAIN we can easily catch it, but the controller will retry on failure anyways so this behavior is fine.

Comment 21 Amarnath 2022-10-02 17:21:52 UTC

Hi @khiremat,

I am able to set file quota to subvolumegroup.
Here is the scenario i tried

Created SubvolumeGroup
File quota set to 3

with this, I am able to create more than three subvolumes.I tried to create 4 and it did not throw any error
When I try to create file inside the subvolume it fails with the quota exceeded error.

Can you comment on the above Scenario?


Regards,
Amarnath

Hi Kotresh,

Below are the scenarios that have been tested with respect to subvolumegroup bytes quota.
Could please point if we have to validate any other things.


Subvolume is allowing to set larger value than subvolumegroup  -- Failed

Hi Kotresh,

I was thinking this was related to attributes quota.
Thanks for PR details.
Now I have tested it as a parameter which has been introduced as part of subvolumegroup creation
