    • ALL

      We have mongodb 5.0, shurded cluster with one shard.
      Config servers - 6 nodes, 3 in main data center, 3 in second data center. In second data center 1 node has votes = 0, all nodes in second data center have priority = 0.
      Data replica set - 6 nodes, 3 in main data center, 3 in second data center. In second data center 1 node has votes = 0, all nodes in second data center have priority = 0.
      During some period of time we had network problems between main and second data centers. We still had majority 3 voting nodes of 5, but app had errors:
