Thanks Christopher!
That will force me to have as many gluster storages as hosts? Or it will a=
llow
to have one gluster setup with each of the hosts accessing to the local sto=
rage?
I will investigate, but I'd prefer if I did not have to use any external
service at all (in the end, is just local storage)

Hi David,

You could use a local replica-1 gluster storage domain for this.
replica-1 =3D> no split brains + local performance + no complexity + no
overhead + gluster benefits
It just works fine.

PS: I'm currently researching the best way to live replicate local replic=
a-1
volumes by using geo-replication, adding a replica-2 brick, using
libvirt
blockcopy or oVirt API.

Best regards,
Christopher.
