    Pacemaker/Corosync not able to failover on NIC failure


    ENVIRONMENT
    OS = RHEL 7.4
    HA NODES = 2 virtual machines
    PRODUCT = CoroSync/Pacemaker
    RING CONFIGURED = 2

    ISSUE
    Resource Group is able to failover when I reboot active node. However when I down Ethernet(ifconfig eth0 down OR ifdown eth0), then the resource group is unable to failover to standby node.

    # pcs resource
    Resource Group: SERVICEGROUP-XXXX
    VOLUMEGROUP (ocf::heartbeat:LVM): Started COM1-XXXXX
    FILESYSTEM (ocf::heartbeat:Filesystem): Started COM1-XXXXX
    VIP (ocf::heartbeat:IPaddr2): Started COM1-XXXXX
    REDIS (ocf::heartbeat:redis): Started COM1-XXXXX
    XXXX (ocf::heartbeatxxx): Started COM1-XXXXX
    PUBLIC-VIP (ocf::heartbeat:IPaddr2): Started COM1-XXXXX

    then call redhat support theyll help you. going to use something you should pay for then dont steal it. your probably missing a ton of patches and havent followed their docs on installing things.

    because if you actually 'logged the case", youd get an answer. there arent different opinions to get something working. this isnt programming where there are tons of answers this is system config. it either works or not and isnt open to 'opinions".

    you didnt set it up correctly and I doubt you have rhel support. their knoweldgebase (which you can read if you PAY FOR IT) has complete instructions. if your patched and have followed them it'll work with no 'opinion" involved.

    if your not paying then you DO NOT have the patches and things WILL NOT work.
