    Description

      This issue was created by maloo for Andreas Dilger <adilger@whamcloud.com>

      This issue relates to the following test suite run: https://testing.whamcloud.com/test_sets/470452f2-b812-4f0e-9ba3-0a16eb2284c4

      test_56wc failed with the following error:

      md5sum: /mnt/lustre/d56wc.sanity/f56wc.sanity: Invalid argument
      file data has changed (1)
      

      Test session details:
      clients: https://build.whamcloud.com/job/lustre-master/4615 - 5.14.0-427.42.1.el9_4.x86_64
      servers: https://build.whamcloud.com/job/lustre-b2_15/100 - 4.18.0-553.27.1.el8_lustre.x86_64

      It looks like this has failed interop testing 100% with b2_15 servers and master clients since 2025-03-14 and was passing 100% before 2025-03-06:
      https://testing.whamcloud.com/search?client_branch=master&server_branch=b2_15&horizon=15552000&test_set_script_id=f9516376-32bc-11e0-aaee-52540025f9ae&sub_test_script_id=24b24afa-b8f6-11e7-8afb-52540065bddc&source=sub_tests#redirect

      It doesn't look like it relates to kernel versions on the client and server, so it is likely related to a landing at that time.
