[LU-12869] interop: lustre-rsync-test test 2a fails with 'Failure in replication; differences found.'

Duplicate — Wed, 12 Aug 2020 09:22:32 +0000

We have seen lustre-rsync-test test_2a fail with 'Failure in replication; differences found.' once for 2.10.8 servers and 2.12.3 RC1 testing; see https://testing.whamcloud.com/test_sets/93e5d5ae-eac2-11e9-9874-52540065bddc . Note that this test fails 100% of the time for PPC client testing. This ticket does not cover the PPC failures.

In the suite_log, we don’t see any obvious errors
