[Gluster-devel] BUG Report: (unify) adding more servers to the cluster may result in inaccessible directory

[Amar S. Tumballi]

Hey,
 Nice notice. But I think we have said about it in our document that the underlying
rule for glusterFS is that directories are created in every server. This is known 
bug for us. Sure, this problem is not handled in unify, and 'fsck' should solve
the probelm. 

 Thanks for mailing us the bug, please wait till our next release (refer roadmaps) 
to solve this issue.

Happy hacking,
- bulde
