Following should have happened, If delete operation is performed gluster 
keeps file in .unlink directory if it has open fd.
In this case since lazy umount is performed, ganesha server may still 
keep the fd's open by that client so gluster keeps
the unlink directory even though it is removed from fuse mount.
