Just to make it clear that before downgrade, need run "tune2fs -O ^quota" on all MDT and OST devices.

Hi Johann,

Cliff is working on the performance part(section 4), I don't have the permission to access Hyperion. Section 5(DNE part) is now skipped, and for the rest of part have all been tested(by autotest or manually).

[Johann Lombardi (Inactive)]

That's good news.

Sarah, could you please share with me the performance numbers?

[Jodi Levi (Inactive)]

It appears the tests were run twice on the 2.3.59 tag on both ldiskfs and ZFS and all passed.
Sarah can comment more.

[Johann Lombardi (Inactive)]

Have we finally run the whole test plan? No major issues found?

Sarah, it looks good to me. Thanks.

For the online OST addition testing, here are the test steps, please comment if it is not enough.

1. set up lustre with one OST-0, enable quota and create a file then use up all the blocks
2. online OST addition to the file system
3. check if the quota is enabled on the new OST-1
4. create a new file make sure it is on the new OST-1 and then write, should expect EDQUOT
5. delete the first file on OST-0 and write again on OST-1, should expect success

I have updated the document. I think we need to run the same test with a lustre version <2.4 in order to compare.

Johann,
Can you please add the details for what the performance test should entail? Also, how is Quota enabled on Hyperion?
Thank you!

Does this need to be stressed at scale?

Yes, it would be great to run the performance test on hyperion.

If no: does this have a feature that needs to be enabled or disabled during normal SWL testing?

I don't think SWL has any special code for quota. That said, we can probably run it on a filesystem with quota enabled.
