[lustre-discuss] Inquiry Regarding LBUG Issue in Lustre 2.15.5 with RoCE and Sanity Test Coverage

[권세훈]

Hello,

My name is Sehoon Kwon, and I’m a developer at Gluesys, a storage solution provider based in South Korea.

We are currently working with Lustre version 2.15.5, and during testing in a RoCE environment, we encountered an LBUG issue. Upon checking the community issue tracker (LU-16637), we confirmed that a similar issue had been reported and resolved in a later release (Lustre 2.16).

We also noted that there had been an effort to backport the fix to the b2_15 branch. However, based on our investigation, it appears that the patch has not yet been merged. As the stability of the fix remains unverified in this branch, we are preparing to evaluate the patch internally, referring to the Mallo-based testing you conducted as a reference.
We have backported the commit addressing LU-16637 to our ZFS-based Lustre 2.15.5 environment and successfully completed the build process, along with several other fixes.

Following the Testing HOWTO on the Lustre Wiki, we executed sanity.sh and observed that the script includes nearly 1000 test cases. However, in some shared test logs from Whamcloud, we noticed that only around 300 tests were actually run.

We would appreciate your clarification on the following points:


 
 Are there any default test sets or predefined exclusions when running sanity.sh?
  Alternatively, does Whamcloud maintain an internal list of commonly executed tests?
 
 
 For the 2.15 branch, is there any recommended test suite or guideline for verifying backported patches?
 
 
 In addition to the sanity suite, we are aware of several other test categories.
  If there is a commonly used baseline set for general validation, your guidance would be greatly appreciated.
 


We aim to align our testing with community standards and ensure compatibility and stability, so any information or reference materials you could provide would be of great help.

Thank you very much for your support.

Best regards,
Sehoon Kwon
