SMB witness client error as critical

  • This is the 1st time I have seen this error as critical in an event viewer and not sure how to resolve it since there is not much info on google. We have a 2 node cluster , up and running with no issues. The error is "Witness Client failed to find a Witness Server for NetName \\Fileshare\ with error (A remote procedure call (RPC) protocol error occurred.). Retrying in (15) seconds." Any info is highly appreciated.

    "He who learns for the sake of haughtiness, dies ignorant. He who learns only to talk, rather than to act, dies a hyprocite. He who learns for the mere sake of debating, dies irreligious. He who learns only to accumulate wealth, dies an atheist. And he who learns for the sake of action, dies a mystic."[/i]

  • This is outside my area but my 2 pennies: Witness Client and Witness Server are used to keep the cluster in sync.  The error appears to have triggered a retry policy.  Can you see if the retries failed too?  If the retries are failing too then that's really not good.  The first thing I would look at is whether or not there are any packet losses in the network.  If a network instability is causing intermittent disruptions it would cause retries, some of which might work and some might fail again.
