Cluster Network Question

[yena]

Hello,
in a 4 nodes cluster, is it better to configure the cluaster network on the WAN (public ip) or using
a dedicated (LAN) network like 192.168.1.x ?

Thanks!

Hi,

use a dedicated network if you have one.
If you want enable HA you need anyway a redundant Cluster network.
see

and

So for a minimal safe config:
2 Eth for the storage ( bonding )
2 Eth for the Lan HA network (bonding)
1 Eth for Wan -> internet

Is it correct ?

Thanks!

Yes this is correct for HA

Why not bonded WAN? Are these VM unreachable from WAN side?
