[Gluster-devel] bit rot support for glusterfs

Is an optimization possible for Btrfs that avoids GlusterFS level checksums entirely? Even with data raid0, by default it writes metadata with raid1, and can determine file corruption. Such corruptions are reported by pathtofile by Btrfs. If that can be communicated to glusterfs, glusterfs could initiate repair by getting a good copy from another brick to forward to the application layer, and then initiate an overwrite for that file on the brick with the bad copy.
