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.
