  • Repeated connection errors on Hyperscale Servers
    Posted: 03-07-2020, 8:30 PM

    We are seeing connection related errors in syslog on all our Hyperscale servers.  They appear to be benign but can someone please shed some light on what these mean and whether or not they can be ignored, or better yet disabled?   Thanks.

     

    The following errors just continue to spew to syslog:

    Mar 7 19:24:36 menpcvs02p journal: Request to server http://0.0.0.0:2379 failed: MaxRetryError("HTTPConnectionPool(host='0.0.0.0', port=2379): Max retries exceeded with url: /v2/keys/nodes/d1f7d754-f5b2-4d2a-b4c1-d3e968b8a84c/NodeContext/data?quorum=true (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f4cacbbe450>: Failed to establish a new connection: [Errno 111] Connection refused',))",)

    Mar 7 19:24:36 menpcvs02p tendrl-node-agent: Error connecting to central store (etcd), trying again...Request to server http://0.0.0.0:2379 failed: MaxRetryError("HTTPConnectionPool(host='0.0.0.0', port=2379): Max retries exceeded with url: /v2/keys/nodes/d1f7d754-f5b2-4d2a-b4c1-d3e968b8a84c/NodeContext/data?quorum=true (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f4cacbbe450>: Failed to establish a new connection: [Errno 111] Connection refused',))",)

    Hi BillyK,

     

    which feature release and maintenance release (service pack.hotfix pack) are you on now?

    if you are not seeing any problems in the environment then it looks like some of those errors you mentioned were resolved with 16.34

    https://documentation.commvault.com/commvault/v11_sp16/article?p=SP16_34.htm

    2113 - HyperScale appliance may generate spurious alerts for brick daemon status

    2114 - Hardware alert 'NIC disconnected' may be reported incorrectly in HyperScale appliances
