I have a cluster of identical computers. We are planning to add more nodes later. I was thinking whether I should go the diskless nodes way or not? Diskless nodes seems as a really exciting, interesting and good option, however when I did it I needed to troubleshoot a lot. I did fix it up, but I had to redo the filesystem, but the past experiences didn't make much of a difference. I still need to fix up everything, I kinda need your help to decide. Also, performance wise, I was thinking that diskless is not a good option, and since performance matters . . . Can somebody outline the pros and cons of each or just give me thier opinion.
