From 246a6b572458af000a216f1e00ba1dea9414c7d6 Mon Sep 17 00:00:00 2001 From: Boaz Harrosh Date: Fri, 6 Jan 2012 09:28:12 +0200 Subject: [PATCH] pnfs-obj: pNFS errors are communicated on iodata->pnfs_error commit 5c0b4129c07b902b27d3f3ebc087757f534a3abd upstream. Some time along the way pNFS IO errors were switched to communicate with a special iodata->pnfs_error member instead of the regular RPC members. But objlayout was not switched over. Fix that! Without this fix any IO error is hanged, because IO is not switched to MDS and pages are never cleared or read. [Applies to 3.2.0.
