[Gluster-users] Running Gluster client/server on single process

[Tejas N. Bhise]

Hi Bryan,

3.0.5 should be out soon. If you want to do some testing before it's officially out, you can try the latest release candidate. You don't need to patch at this stage. Let me know if you know how to get the release candidates and use them.

Regards,
Tejas.

Tejas,

Any idea when 3.0.5 will be released? I am very anxious for these  
patches to be in production.

On another note, I am very new to Gluster let alone Linux. Could you,  
or someone else, give me some guidance (How to) in applying the  
patches. I would like to test them for now?
