Re: [Gluster-devel] GlusterFS 3.0pre1 (Whats in 3.0)

Nathan,
    
    aio with directio is still work in progress which can be tracked here 
    http://git.gluster.com/?p=users/csaba/linux-fusehacks/.git;a=shortlog;h=refs/heads/topic.directio1 
    This needs to be fixed in the fuse kernel module itself.  I think this is what you were
     looking at perhaps. 

    Well disable-direct-io can be done away as since 2.6.26 fuse kernel module supports
    big_writes which even with disabling direct io you get good performance.

Key highlights of 3.0 are
* Background self-healing: Applications won't be blocked any more during healing operation.
* Checksum based healing: Rsync like healing mechanism to heal only the inconsistent blocks within a file.
* Healing on the fly: Files can be healed even when the files are open and application is performing active I/O.
* Generation numbers: Self-healing can now reliably handle tricky corner cases (such as "rm -rf" bug).

Great list! I assume direct-io will be supported for virtualization as well? The above and disable-direct-io are the last things keeping us from launching Gluster on our Xen cluster.
