AWS Pacemaker awsvip failing with different errors

[jayan800]

Hi All,

We are running a two node pacemaker cluster in AWS and we use "awsvip" resource type to configure the vip IP. Below is the conf

pcs resource show privip_node1

Resource: privip_node1 (class=ocf provider=heartbeat type=awsvip)
Attributes: secondary_private_ip=10.x.x.x
Operations: migrate_from interval=0s timeout=30s (privip_node1-migrate_from-interval-0s)
migrate_to interval=0s timeout=30s (privip_node1-migrate_to-interval-0s)
monitor interval=20s timeout=30s (privip_node1-monitor-interval-20s)
start interval=0s timeout=30s (privip_node1-start-interval-0s)
stop interval=0s timeout=30s (privip_node1-stop-interval-0s)
validate interval=0s timeout=10s (privip_node1-validate-interval-0s)

pcs resource show node1_vip

Resource: node1_vip (class=ocf provider=heartbeat type=IPaddr2)
Attributes: ip=10.x.x.x
Operations: monitor interval=10s timeout=20s (node1_vip-monitor-interval-10s)
start interval=0s timeout=20s (node1_vip-start-interval-0s)
stop interval=0s timeout=20s (node1_vip-stop-interval-0s)

The EC2 instance is configured to use IMDSV2.The fence_aws agent and resource-agent have also been upgraded to the most recent versions, which support imdsv2. Additionally, the resource is set up to use the IAM Profile credentials.

fence-agents-aws-4.2.1-41.el7_9.3.x86_64
python-s3transfer-0.1.13-1.0.1.el7.noarch
resource-agents-4.1.1-61.el7_9.15.x86_64

pip list | grep -i boto
boto3 (1.10.0)
botocore (1.13.50)

pip3 list | grep -i boto
boto3 1.23.10
botocore 1.26.10

The privip resource consistently fails with the different errors:

Any advice would be great.

Try running pcs resource debug-start --full <resource>. That should show you all the commands it's running, and hopefully some pointers to what's wrong.

[jayan800]

Thank you.

The debug command completed without any errors.

is there anything else to check?

[oalbrigt]

You can run pcs resource update <resource> trace_ra=1 and then disable/enable or restart the resource.

The trace files will be available in /var/lib//heartbeat/trace_ra/.

[jayan800]

Thank you. I will enable the trace.
fingers crossed
