01- HA High Availability ( Training and Conductor onboarding )
Terraform automarion: HA Conductor on Azure with Terraform
| initialize | |
|---|---|
| node1 | redo the initialization as HA with Node1 and node2 |
| node2 | redo the initialization as HA with Node1 and node2 ( new asset-id ) |
| Global config | Create two nodes |
| Clock Synchronization | authority > router > system > ntp: pool.ntp.org ( like on Mist ) |
| DNS config | Static DNS ( 1.1.1.1 and 8.8.8. |
| 8 1- when using static 2- not been configure at the interface) | |
Management flag = True ( to allow NDS, NTP: "mgt" protocols SNMP, . . . ) | |
HA-Sync Interface Redundancy link | Option 1: Directly connected ( cable between the two nodes ) only SYNC Interface: Fabric IF + non-forwarding |
|---|---|
| https://docs.128technology.com/docs/config_non_forwarding_ha_interfaces | |
| Device-interface: HA-Sync | Forwarding = False ( stay in Linux ) |
| Netw interface | Basic Information, type: Fabric IP@ |
/ 30 ( example: 192.168.111.1/30 and 192.168.111.2/30 ) 192.168.111.1 1192.168.111.)192.168.111.1 | |
| Linux | ifcfg Option: ZONE= trusted >> allow to conductor to talk to the node, thru the other node |
| Restart 128T | |
Option 1: Not-Directly connected ( switch / router between the two nodes ) Shared + non-forwarding | |
|---|---|
| Netw interface | Basic Information, type: Shared IP@ / 30 or else |
| HA-Fabric interface: | Option 2: Fabric ( directly connected) + Forwarding this interface is a forwarding interface between two nodes in a router, |
| HA-Sync | Forwarding= False |
| Device-interface: HA-Fabric | Forwarding= True PCI Address: |
| |
| Netw interface: HA-Fabric | Basic Information, type: Fabric |
| |
| Restart 128T | |
| Clone the node1 | |
|---|---|
| Node2 software | make sure node has the same software release |
| |
| WAN Link | Option 1: Shared physical |
| 1- same shared mac address 2- same global ID | |
| Device-interface | create a "Shared physical/ MAC addresses" ( copy Node 1) |
| Network-interface | ( first node1 ) clear the global id ( copy Node 1) |
| Redundancy Group | redundancy-group configuration |
@Router > Redundancy Group>>> Node2,
| |
| WAN Link | Option 2: VRRP |

| LAN Link | |
| device | Device-interface shared-phys-address 0C:C4:7A:AB:37:8D
|
| Both have exactly the same config |
