The issue is seen in interop testing with Lustre clients 2.12.3.57 and later with any server with version less than 2.12.3.57. Patch https://review.whamcloud.com/36406/ for LU-11670 adds sanityn test 103 and landed to b2_12 on 12 December 2019. The test has a version check, but it may not be the correct version

4734 test_103() {
4735         [ $(lustre_version_code $ost1) -lt $(version_code 2.10.50) ] &&
4736                 skip "Lockahead needs OST version at least 2.10.50"
