From f46a3198b1a3d794c23b8ac2ab9334326c4918c8 Mon Sep 17 00:00:00 2001 From: Venkatesh Somyajulu Date: Fri, 3 Jan 2014 13:54:25 +0530 Subject: cluster/afr: Unable to self heal symbolic links Problem: Under the entry self heal, readlink is done at the source and sink. When readlink is done at the sink, because link is not present at the sink, afr expects ENOENT. AFR translator takes decisions for new link creation based on ENOENT but server translator is modified to return ESTALE because of which afr xlator is not able to heal. Fix: The check for inode absence at server includes ESTALE as well.
