Hi Xiubo,
I uploaded a test script with session output showing the issue. When I look at
your scripts, I can't see the stat-check on the second host anywhere. Hence, I
don't really know what you are trying to compare.
Frank,
I did that manually and that's not included in the script.
If you want me to run your test scripts on our system for comparison, please
include the part executed on the second host explicitly in an ssh-command.
Running your scripts alone in their current form will not reproduce the issue.
I saw your updating in the tracker and I will try it.
Thanks

Hi Xiubo,
thanks for the update. I will test your scripts in our system next week.
Something important: running both scripts on a single client will not produce a
difference. You need 2 clients. The inconsistency is between clients, not on
the same client. For example:
Frank,
Yeah, I did this with 2 different kclients.
Thanks
Setup: host1 and host2 with a kclient mount to a cephfs under /mnt/kcephfs
Test 1
- on host1: execute shutil.copy2
- execute ls -l /mnt/kcephfs/ on host1 and host2: same result
Test 2
- on host1: shutil.copy
- execute ls -l /mnt/kcephfs/ on host1 and host2: file size=0 on host 2 while
correct on host 1
Your scripts only show output of one host, but the inconsistency requires two
hosts for observation. The stat information is updated on host1, but not
synchronized to host2 in the second test. In case you can't reproduce that, I
will append results from our system to the case.
Also it would be important to know the python and libc versions. We observe
this only for newer versions of both.
Best regards,
