Dear All, I just implemented a (6x(4+2)) DISTRIBUTED DISPERSED gluster (v.3.10) volume based on the following hardware: - 3 gluster servers (each server with 2 CPU 10 cores, 64GB RAM, 12 hard disk SAS 12Gb/s, 10GbE storage network) Now, we need to add 3 new servers with the same hardware configuration respecting the current volume topology. If I'm right, we will obtain a DITRIBUTED
