This issue was created by maloo for Andreas Dilger <[e-mail]>

This issue relates to the following test suite run: https://testing.whamcloud.com/test_sets/82a7f1ec-1aec-4c81-9abf-64b971919547

test_57b failed with the following error:

Test session details:
clients: https://build.whamcloud.com/job/lustre-b_es6_0/464 - 4.18.0-425.13.1.el8_7.x86_64
servers: https://build.whamcloud.com/job/lustre-b_es6_0/680 - 4.18.0-425.19.2.el8_lustre.ddn17.x86_64

This fails occasionally since 2024-07-28 on various branches.

It seems possible that it may relate to xattrs/ACLs being created on the files, but I would expect the difference in allocated blocks in this case to be a multiple of 100 files created, instead of the 32 or 36 blocks reported.
