    • 2023-12, 2024-1

    Description

      Columnstore has internal metadata deltas stored in a file called BRM_saves_journal.
      By default every 100K BRM changes a new BRM_saves version is saved. Starting with BRM_savesA then BRM_savesB. The current version is tracked in BRM_saves_current.

      The problem occurs when the system BRM_saves_current=BRM_savesB and the system inproperly shutdown or cant complete. On startup, the system complains

            Here it is the guide to manually increase timeout:

            1. stop the cluster if running
            2. change the TimeoutStopSec value to 900 in /usr/lib/systemd/system/mcs-workernode@.service
            3. run sudo systemctl daemon-reload --all
            4. check the timeout changed by running command sudo systemctl show mcs-workernode@1.service -p TimeoutStopUSec
            5. start cluster
