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 On 4/5/07, Anand Babu Periasamy <ab@xxxxxxxxxx> wrote:
