sanity-hsm test_604 fails with 'No matching NOPEN entry'. Looking at the suite_log, the full output from test_604 is

  Trace dump:
  = /usr/lib64/lustre/tests/test-framework.sh:5900:error()
  = /usr/lib64/lustre/tests/sanity-hsm.sh:5571:test_604()

The ‘Permission denied’ cat errors are seen in tests that pass, but, in those tests we do see another NOPEN entry in the changelog after the third cat of the file.

There is nothing of interest in the console logs.

We’ve seen this error twice for RHEL 8 clients starting 10 JAN 2020
2.12.4 https://testing.whamcloud.com/test_sets/fd46e654-349c-11ea-adca-52540065bddc
2.14.0 (ARM client) https://testing.whamcloud.com/test_sets/27e8c5e0-35a0-11ea-b1e8-52540065bddc

Note: PPC client have failed this test for at least the past year with the same error message, but these failures have the additional error “lfs changelog: cannot access changelog: Invalid argument” and many sanity-hsm tests fail before test 604. Thus, I think the PPC client failures for this test are different from the RHEL8 failures.
