It lists interfaces using the 'inet' family, which omits interfaces that don't have an IP address assigned. If the interface that we're looking for is e.g. a VLAN bridge that does not have an IP address, it won't show up in the listing and is_interface() will return false. ethmonitor will miss that interface, and it won't be available for monitoring. Upstream commits: - https://github.com/ClusterLabs/resource-agents/commit/40d05029ce0b - https://github.com/ClusterLabs/resource-agents/commit/c0ac191c73f1 [Test Case] 1) Ensure there's a network interface without an assigned IP address. For example, virbr0-nic will be created automatically by uvt-kvm: # ip addr show dev virbr0-nic 11: virbr0-nic: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel master virbr0 state DOWN group default qlen 1000 link/ether 52:54:00:e9:5e:af brd ff:ff:ff:ff:ff:ff 2) Install pcs+arping and create a new ethmonitor resource with the target interface: # sudo apt update && sudo apt install pcs arping -y # pcs resource create p_nic ocf:heartbeat:ethmonitor interface=virbr0-nic op monitor timeout="10s" 3) Debug-start ethmonitor resource and check for "Interface does not exist messages" # pcs resource debug-start p_nic Operation start for p_nic (ocf:heartbeat:ethmonitor) returned: 'ok' (0) > stderr: WARNING: Interface virbr0-nic does not exist > stderr: NOTICE: link_status: DOWN [Regression Potential] The regression potential is low, since we are relaxing the monitoring conditions for interfaces without an assigned IP address. The patches have been tested against Travis-CI before being merged upstream, and will be tested against autopkgtest for each target distro.
