From cc9d3c382bc1674884c2e5e468d51230a9503dee Mon Sep 17 00:00:00 2001 From: Jun'ichi Nomura Date: Fri, 13 Sep 2013 14:54:30 +0900 Subject: [PATCH] dm mpath: do not fail path on -ENOSPC Since ENOSPC is a target-side error, dm-mpath should just pass the error information to upper layer instead of retrying itself with path failover. Otherwise it will end up failing all paths down while path checkers find all paths ok. ENOSPC can now be returned from SCSI device after commit a9d6ceb8 ("[SCSI] return ENOSPC on thin provisioning failure").
