Description

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/dc77145c-b7d3-4010-a7a2-f8435f9353ff

Test session details:
clients: https://build.whamcloud.com/job/lustre-reviews/101478 - 4.18.0-477.27.1.el8_8.x86_64
servers: https://build.whamcloud.com/job/lustre-b2_15/81 - 4.18.0-513.9.1.el8_lustre.x86_64

there are a number of sanity interop test failures with 2.15.4 servers

Please review the test failures to determine for each one:

• when did the failure first start happening?
• is this a new test added since 2.15.50 was forked from b2_15?
• should the test be skipped because of an older MDS or OSS version?
• is this a legitimate regression?
• if not a clear case of new test with old server, ensure an LU ticket is open for it with details and add to always_except
