      Description

      sanity test_271f started failing on November 27, 2018 with the error '1 READ RPC occured'. So far, this failure is only seen with non-DNE and ZFS configurations.

      Looking at the logs for a recent failure at https://testing.whamcloud.com/test_sets/faa5559a-f9ef-11e8-8512-52540065bddc , the client test_log contains

      There is no indication of any problems in the console logs.

      This failure looks different from LU-11532 in that this failure does not look like a bash/test error. In early November, there was a modification made to this test by path https://review.whamcloud.com/33490 , but the start of these failures is delayed from the landing of this patch.
