From cbdabc7f8bf14ca1d40ab1cb86f64b3bc09716e8 Mon Sep 17 00:00:00 2001 From: Andy Adamson Date: Tue, 1 Mar 2011 01:34:20 +0000 Subject: NFSv4.1: filelayout async error handler Use our own async error handler. Mark the layout as failed and retry i/o through the MDS on specified errors. Update the mds_offset in nfs_readpage_retry so that a failed short-read retry to a DS gets correctly resent through the MDS.
