[LU-12656] sanity-flr test 200 fails with 'failed writing to :’

Duplicate — Thu, 6 Jul 2023 01:00:56 +0000

sanity-flr test_200 fails with messages similar to 'failed writing to 1540352:850912'. It looks like this test is failing for “new” kernels running for Ubuntu 18.04 and RHEL8 clients. This issue started around 5 May 2019.

Looking at the client test_log for https://testing.whamcloud.com/test_sets/f6a78ce6-b5bb-11e9-b88c-52540065bddc, we see a lot of resync failures and a write ‘input/output error’:
