Subject: [PATCH] aws-vpc-move-ip: Don't warn for expected scenarios
|
|
|
030326 |
|
|
|
030326 |
Make log levels more appropriate to the situation. Before this patch, a
|
|
|
030326 |
normal start looked like this:
|
|
|
030326 |
|
|
|
030326 |
Operation start for aws-vip (ocf:heartbeat:aws-vpc-move-ip) returned: 'ok' (0)
|
|
|
030326 |
> stderr: Nov 09 02:38:20 INFO: EC2: Moving IP address 10.0.1.65 to this host by adjusting routing table rtb-01b4ea1ae0ec0a4d9
|
|
|
030326 |
> stderr: Nov 09 02:38:20 INFO: monitor: check routing table (API call) - rtb-01b4ea1ae0ec0a4d9
|
|
|
030326 |
> stderr: Nov 09 02:38:22 WARNING: IP 10.0.1.65 not assigned to running interface
|
|
|
030326 |
> stderr: Nov 09 02:38:22 INFO: EC2: Adjusting routing table and locally configuring IP address
|
|
|
030326 |
> stderr: RTNETLINK answers: Cannot assign requested address
|
|
|
030326 |
> stderr: Nov 09 02:38:24 WARNING: command failed, rc 2
|
|
|
030326 |
> stderr: Nov 09 02:38:24 INFO: monitor: check routing table (API call) - rtb-01b4ea1ae0ec0a4d9
|
|
|
030326 |
|
|
|
030326 |
Now it looks like this:
|
|
|
030326 |
|
|
|
030326 |
Operation start for aws-vip (ocf:heartbeat:aws-vpc-move-ip) returned: 'ok' (0)
|
|
|
030326 |
> stderr: Nov 09 02:40:43 INFO: EC2: Moving IP address 10.0.1.65 to this host by adjusting routing table rtb-01b4ea1ae0ec0a4d9
|
|
|
030326 |
> stderr: Nov 09 02:40:43 INFO: monitor: check routing table (API call) - rtb-01b4ea1ae0ec0a4d9
|
|
|
030326 |
> stderr: Nov 09 02:40:44 INFO: IP 10.0.1.65 not assigned to running interface
|
|
|
030326 |
> stderr: Nov 09 02:40:44 INFO: EC2: Adjusting routing table and locally configuring IP address
|
|
|
030326 |
> stderr: Nov 09 02:40:46 INFO: monitor: check routing table (API call) - rtb-01b4ea1ae0ec0a4d9

Under normal circumstances, the call to `ec2ip_drop()` within
|
|
|
030326 |
`ec2ip_get_and_configure` should not be required at all. The drop
|
|
|
030326 |
function deletes the address before the get_and_configure function
|
|
|
030326 |
immediately re-adds the address. This call could probably be removed
|
|
|
030326 |
altogether. Instead, I left the call and silenced its output just in
|
|
|
030326 |
case of unexpected edge cases.
|
|
|
