Yujian, you can verify by doing a yum install posix on any node. If the src include your change, then we are good. If not, please contact Joshua to sync the repo with yum

Thanks Minh for this info. I've verified this by provisioning Lustre 2.1.3 test nodes and run posix test on them, the posix-1.0-wc1 package contained the new changes and posix test passed:

The change on LSB-VSX POSIX test suite has been pushed into the toolkit repository. Let's wait for a successful posix test run performed by autotest and then we can close this ticket as resolved.

I just verified again that the same failure also occurred on ext4 filesystem. After updating the LSB-VSX POSIX test suite to disable the terminal file test in pathconf.32, Lustre POSIX compliance testing passed on T.pathconf test set (baseline is ext4):

Lustre branch: master

Actually, Yujian is working on a fix.

This item needs to be added to the release notes.

The unlink.6 and write.15 failures are LU-380. The readdir.6 failure is LU-379. This ticket is used to track pathconf.32 failure.

I found that while formatting a partition/disk as ext4 filesystem and run POSIX test suite on it to generate baseline, the pathconf.32 test also failed. However, if a loop device is used to be formatted as ext4, the test passed. So, the issue is related to the baseline, not Lustre.

Since Lustre never pass all the POSIX test cases. We need to check whether above failures are new ones or known issues.

Yu Jian,
Can you please take a look at this one?

I have reproduced this manually. This seems like Posix issue
