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/518ae7e9-ea71-4133-871f-affeadf6ec72

test_27Cg failed with the following error:

Timeout occurred after 112 minutes, last suite running was sanity

Test session details:
clients: https://build.whamcloud.com/job/lustre-master/4415 - 4.18.0-425.10.1.el8_7.x86_64 (2.12.9)
servers: https://build.whamcloud.com/job/lustre-b2_12/164 - 3.10.0-1160.49.1.el7_lustre.x86_64 (master)

The patch https://review.whamcloud.com/50487 "LU-16693 lod: ENODEV on setstripe with wrong OST#" landed in commit v2_15_55-80-gd96b98ee6b fails 100% in interop mode because it tries to create an invalid file layout, but the error return code -ENODEV from an old server will be retried indefinitely by the client. The patch fixes the server to return -EINVAL, but that fix is not present on old servers, so the subtest needs to be skipped in this case.
