Enhance dsreplication to allow marking a server as being offline

    Details

    • Type: Improvement
    • Status: Dev backlog
    • Priority: Major
    • Resolution: Unresolved
    • Affects Version/s: 4.0.0
    • Fix Version/s: None
    • Component/s: devops, replication
    • Labels:
      None

      Description

      When a DS stops without sending a replica offline message, it blocks computing of the change number on the replication servers. Various reasons exist for a DS to stop abruptly:

      • kill -9
      • linux OOM killer
      • when the machine where a DS is installed dies and is irrecoverable
      • etc.

      To unblock computing of the change number, we could add a subcommand to dsreplication that would (in the end) send a ReplicaOfflineMsg on behalf of the DS that is gone. This will tell the replication servers to not wait for it when computing change numbers.
