From 2379475bda40de6349e94506e0c7ea9386c9b514 Mon Sep 17 00:00:00 2001 From: Kaushal M Date: Mon, 31 Oct 2011 12:33:50 +0530 Subject: cluster/afr : Fix self-heal of special files Fixes self-heal of special files like device files, fifo files, socket files etc. Does it by doing the following: * Prevent setting of pending data xattr on a special file during entry self-heal when a new file is created. * Allow data self-heal to be started on all file types other than directories. During data self-heal, for special files just erase pending xattrs, if those xattrs were set by previous releases of glusterfs.
