Opened: Sep 02, 2017
Severity: 3-Major

Symptoms

Pool members or nodes that utilize an ICMP monitor are marked down even though they are actually up. This issue only affects objects in route-domains that were removed and recreated.

Impact

Pool members or nodes are marked down incorrectly.

Conditions

The configuration utilizes ICMP monitors in a non-default route-domain and, at some point in the past, the route-domain was deleted and recreated while ICMP monitors were in use in that route-domain.

Workaround

To avoid the issue, remove icmp monitors for pool-members and nodes before deleting the route-domain. Reapply the monitors after the route-domain is recreated. To correct the issue, restart the bigd process using the following command: tmsh restart sys service bigd.

Fix Information

Pool-members and nodes that utilize an ICMP monitor are no longer incorrectly marked down after the route-domain containing them is deleted and recreated.
