[Gluster-devel] GlusterFS 1.3.0-pre2.3: AFR not working

GlusterFS doesn't have an automated repair (resync if node goes down), 
yet.  However, an rsync should do the trick until they have their 
"self-healing" in place.  The roadmap shows the self-healing feature as 
the next release, although it also shows that the release should have 
already happened. ;-)

Does anyone have a guesstimate as to when self-heal (or at least a roadmap 
update) might appear?



PS I just noticed the client-side inode item on the roadmap; that should 
fix the KDE problem mentioned on the list a few messages ago, as well as 
allow hardlinks, correct?
