Thank you all for helping me understand clearly about the 'size'. Ml Ml <mliebherr99@googlemail.com> 于2020年7月10日周五 下午11:08写道：

If size is 2 and one disks fails you are already going to be in error state with read only.

Let's say you reboot one node, you will instantly get into trouble.

If you are going to reboot one node and at the same time the other disk fails, then you very like loose data.

Just never ever use size 2. Not even temporary :)

Hi,

As we all know, the default replica setting of 'size' is 3 which means there are 3 copies of an object. What is the disadvantages if I set it to 2, except I get fewer copies?
