Hi Mauro Tridici,
>From the information provided it appears like you have placed 2 bricks of a
subvolume on one host. Please confirm.
The number of hosts that could go down without losing access to data can be
derived based on the brick configuration/distribution. Please let us know
the brick distribution plan.

> 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 DISPERSED gluster volume with 12
> subvolumes, each volume will contain (4+2) bricks, that is a [12x(4+2)]
> My question is: in the current volume configuration, only 2 bricks per
> subvolume or one host could be down without losing data. What it will
> happen in the next configuration? How many hosts could be down without

> Thank you very much.
