• Type: Bug
• Resolution: Duplicate

• Environment: (So far only) DNE
• Severity: 3

Description

replay-single test_65b fails with 'No early reply'. We see this test fail frequently for PPC64 client testing. If we ignore the PPC failures, we see this test fail for DNE configurations from 16 FEB 2020 with https://testing.whamcloud.com/test_sets/9766a818-51c7-11ea-a90e-52540065bddc. In all of these cases, replay-single tests 0c and 0d fail with 'mount fails' and then a test after 65b will hang.

Looking at the test_suite for a recent failure at https://testing.whamcloud.com/test_sets/2efe802a-db0c-4424-af23-e1a7e8ce99a4, we see the test output
