• Type: Bug

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

Since we are running version interop testing between master (future 2.15.0) and 2.14.0 and latest 2.12, we no longer run interop testing with 2.13.0 and can close this ticket.

2.12 clients don’t support overstripping and are skipped due to a check in sanity-pfl tests 0b and 0c.
2.14.0 client support stripe count limits and these tests don't need to be skipped.
