Description

sanity-pfl test_0b fails for interop testing starting on 24 DEC 2020 for Lustre server version < 2.13.57.36 and Lustre client version >= 2.13.57.36. So far, we only see this failure for 2.13.0 servers and master clients. sanity-pfl test 0b was modified by patch v2_13_57-32-ga58cdc9 (“LU-14191 lod: comp stripe count limit check”). This patch also added sanity-pfl test_0c which is also failing.

Looking at suite_log for the first failure with this error at https://testing.whamcloud.com/test_sets/e26503ed-449e-4070-84e3-8af9d129fad9, we see
