[Gluster-users] [Gluster-devel] missing files

Sorry.  Thought about this a little more. I should have been clearer.  
The files were on both bricks of the replica, not just one side.  So, 
both bricks had to have been up... The files/directories just don't show 
up on the mount.

I was reading and saw a related bug 
(https://bugzilla.redhat.com/show_bug.cgi?id=1159484).  I saw it 
suggested to run:

         find <mount> -d -exec getfattr -h -n trusted.ec.heal {} \;

I get a bunch of errors for operation not supported:

[root at gfs02a homegfs]# find wks_backup -d -exec getfattr -h -n 
trusted.ec.heal {} \;
find: warning: the -d option is deprecated; please use -depth instead, 
because the latter is a POSIX-compliant feature.
