[Gluster-devel] rc8

[Anand Avati]

Ender,
  There was a bug fix which went in to git today which fixes a similar
bug.. a case where a subset of the files would be recreated if there
are a lot of files (~1000 or more) when the node which was down was
the first subvolume in the list. Please pull the latest patches and
see if it solves your case. Thank you for your patience!
