Workflow quota resize - formula issue with spacecalculation

scheckel — Thu, 05 Jun 2025 06:09:07 GMT

Hi,

has somebody done a quota resize workflow.

Example have a volume with some qtrees in it. Customer wants to change the size of one qtree. So volumesize also need to be modified.So usable size should be the sum of all quotas in the volume.

My workflow is ok without snapreserve, but with something the calculation is wrong.

Would be great when somebody can check the formula:

'+' + (int)((size * ('1.' + volume.snapshot_reserved_percent)) - qtree.disk_limit_mb)

I will attach the workflow.

Best wishes,

Markus.

Hi Markus,

The workflow that has been attached when unzipped gives me xml files. We were expecting to see dar files. Could you please reattach the workflow?

Hi Markus,

I have just looked into your formula used for vol size calculation, I think it might required some changes as below,

'+' + (int)( (size * ('1.' + volume.snapshot_reserved_percent) ) - (qtree.disk_limit_mb* ( '1.' + volume.snapshot_reserved_percent)) )

Suppose if your qtree size is 100g then your volume size would be 120g( with 20% snapreseve calcuation)

Then if you are going to increase qtree size to 200g then your volume size needs to be calculated as 240. But with your formula it would be 260, that's why we need to calculate the snapreserve on qtree size as well while deducting it.

Let me know if I'm missing any basic thing here..!
