High availability cluster setup

The following are the minimum version requirements needed to support shared Amazon VPC:

  • Red Hat 7.9 - resource-agents-4.1.1-61.10

  • Red Hat 8.1 - resource-agents-4.1.1-33.10

  • Red Hat 8.2 - resource-agents-4.1.1-44.12

  • SLES 12 SP5 - resource-agents-4.3.018.a7fb5035-3.79.1.x86_64

  • SLES 15 SP2 - resource-agents-4.4.0+git57.70549516-3.30.1.x86_64

  • SLES 15 SP3 - resource-agents-4.8.0+git30.d0077df0-8.5.1

Setup on SLES

  1. Add the overlay ip address to the primary node using the following command.

    prihana:~ # ip address add xxx.xxx.xxx.xxx/32 dev eth0

  2. Create a file named aws-move-ip.txt with the following cluster options.

    
prihana:~ # cat aws-move-ip.txt
primitive res_AWS_IP ocf:suse:aws-vpc-move-ip \
params ip=<overlay ip address> \
routing_table=<route table identifier 1>,<route table identifier 2> \
interface=eth0 \
profile=cluster \
lookup_type=NetworkInterfaceId \
routing_table_role=”arn:aws:iam::<VPC-Account-Number>:role/<VPC-Account-Cluster-Role>” \
op start interval=0 timeout=180 \
op stop interval=0 timeout=180 \
op monitor interval=60 timeout=60

  3. Use the following command to add the overlay ip configuration file to the cluster.

    prihana:~ # crm configure load update aws-move-ip.txt

Setup on RHEL

  1. Add the overlay ip address to the primary node using the following command.

    [root@prihana ~]# ip address add xxx.xxx.xxx.xxx/32 dev eth0

  2. Configure the cluster resource agent according to the following example.

    
[root@prihana ~]# pcs resource create res_AWS_IP aws-vpc-move-ip \
ip=<overlay ip address> \
routing_table=<route table identifier 1>,<route table identifier 2> \
interface=eth0 \
profile=cluster \
lookup_type=NetworkInterfaceId \
routing_table_role=”arn:aws:iam::<VPC-Account-Number>:role/<VPC-Account-Cluster-Role>” \
op start interval=0 timeout=180 \
op stop interval=0 timeout=180 \
op monitor interval=60 timeout=60
