[Gluster-devel] Questions

[Daniel van Ham Colchete]

Anand,

I also agree completly with Gerry. I'll start using GlusterFS in production
for a mail server farm soon and this hot-add/remove is desirable as long as
it doesn't delay the first production ready GlusterFS version. The
self-healing is also a must have. I can't wait to see the 1.4 version ready.

Best regards,
Daniel Colchete
