James Bottomley 77a4229719 [SCSI] Retry commands with UNIT_ATTENTION sense codes to fix ext3/ext4 I/O error ... There's nastyness in the way we currently handle barriers (and discards): They're effectively filesystem commands, but they get processed as BLOCK_PC commands. Unfortunately BLOCK_PC commands are taken by SCSI to be SG_IO commands and the issuer expects to see and handle any returned errors, however trivial. This leads to a huge problem, because the block layer doesn't expect this to happen and any trivially retryable error on a barrier causes an immediate I/O error to the filesystem. The only real way to hack around this is to take the usual class of offending errors (unit attentions) and make them all retryable in the case of a REQ_HARDBARRIER. A correct fix would involve a rework of the entire block and SCSI submit system, and so is out of scope for a quick fix.
