Configuring cleaner schedules

Performing scheduled disk space reclamation operations are recommended as a method for recovering disk space from the system. The recommended method is to schedule a time when you can run the Cleaner on your QoreStor system with no other planned processes running.

Even if no Cleaner schedule is set, but the system detects that there is disk space that can be reclaimed, the Cleaner process runs. However, the Cleaner will not start until the following conditions are met:

  • it detects that there are no active data ingests,
  • that two minutes of system idle time have elapsed since the last data file ingest was completed,
  • and that the Replication process is not running (the Cleaner process runs as a lower system priority operation than the Replication process).

To schedule cleaner operations on your system using the GUI:

  1. On the navigation menu, click System Configuration . In the Cleaner Schedule pane, click Edit Schedule.

    The schedule lists a Start Time and End Time for each day of the week.

  2. For any day on which you do not want the Cleaner to run, click Remove in the Action colum.
  3. For remaining days, edit the Start Time and End Time to set the Cleaner window.
  4. Click Submit

    NOTE: Even if no Cleaner schedule is set, but the system detects that there is disk space that can be reclaimed, the Cleaner process runs. However, the Cleaner will not start until the following conditions are met: it detects that there are no active data ingests, that two minutes of system idle time have elapsed since the last data file ingest was completed, and that the Replication process is not running (the Cleaner process runs as a lower system priority operation than the Replication process).

To schedule cleaner operations on your system using the CLI:

NOTE: The procedure below is a summary. Please refer to the QoreStor Command Line Reference Guide for detailed information on accessing the command line interface for your system as well as using the QoreStor commands.

NOTE: Running the Cleaner while ingesting data reduces system performance. Ensure that you schedule the Cleaner to run when backup or replication is not in progress.

  1. Access the QoreStor command line interface.
  2. Use the QoreStor command line interface (CLI) to create and delete the cleaner schedule. The available commands are: 
      schedule --add --day <Day of the Week> --start_time <HH:MM> --stop_time <HH:MM> --cleaner   

  schedule --delete --day <Day of the Week> --cleaner

    For full details on running the cleaner schedule commands, help is available by entering:

      schedule --help

Viewing cleaner status

The current Cleaner Status is shown in the status pane at the top of the QoreStor UI as one of the three following states:

  • Pending—displays any scheduled window for the Cleaner operation.
  • Running—displays when the Cleaner operation is running.
  • Done—displayed only if there is no Cleaner operation required.

On the System Configuration page, you can also view graphs showing Cleaner runtime and bytes processed.

You may also use the schedule --show --cleaner command to view the cleaner status via the QoreStor command line interface.

Viewing cleaner statistics

To view additional detailed cleaner statistics, you can use the QoreStor CLI stats --cleaner command to show the following categories of statistics:

  • Last Run Files Processed (number of files processed by Cleaner)
  • Last Run Bytes Processed (number of bytes processed by Cleaner)
  • Last Run Bytes Reclaimed (number of bytes reclaimed by the Cleaner)
  • Last Run Start Time (indicates date and time last Cleaner process started)
  • Last Run End Time (indicates date and time last Cleaner process ended)
  • Last Run Time To Completion(s) (indicates the number of times that Cleaner process has successfully completed)
  • Current Run Start Time (indicates date and time current Cleaner process started)
  • Current Run Files Processed (number of files processed by current Cleaner process)
  • Current Run Bytes Processed (number of bytes processed by current Cleaner process)
  • Current Run Bytes Reclaimed (number of bytes reclaimed by the current Cleaner processed)
  • Current Run Phase 1 Start Time (indicates date and time for start of current Cleaner process phase 1)
  • Current Run Phase 1 Records Processed (lists the number of data records processed in current Cleaner process phase 1)
  • Current Run Phase 1 End Time (indicates date and time for end of current Cleaner process phase 1)
  • Current Run Phase 2 Start Time (indicates date and time for start of current Cleaner process phase 2)
  • Current Run Phase 2 Records Processed (lists the number of data records processed in current Cleaner process phase 2)
  • Current Run Phase 2 End Time (indicates date and time for end of current Cleaner process phase 2)
  • Current Run Phase 3 Start Time (indicates date and time for start of current Cleaner process phase 3)
  • Current Run Phase 3 Records Processed (lists the number of data records processed in current Cleaner process phase 3)
  • Current Run Phase 3 End Time (indicates date and time for end of current Cleaner process phase 3)
  • Current Run Phase 4 Start Time (indicates date and time for start of current Cleaner process phase 4)
  • Current Run Phase 4 Records Processed (lists the number of data records processed in current Cleaner process phase 4)
  • Current Run Phase 4 End Time (indicates date and time for end of current Cleaner process phase 4)

Configuring replication schedules

By default, replication of any newly written files in the replicated container will occur when QoreStor detects three (3) minutes of idle time. If you wish to constrain replication activities to a specific schedule, you can configure replication schedules on a weekly basis for individual replication-enabled source containers.

NOTE: It is recommended that you do not schedule the running of any Replication operations during the same time period when Cleaner or data ingest operations will be running. If you do not follow this recommendation, the time required to complete the system operations or system performance might be affected.

To configure replication schedules, complete the following steps.

  1. Access the QoreStor command line interface.
  2. Use the QoreStor command line interface (CLI) to create and delete the replication schedule. The available commands are: 
  schedule --add --day <Day of the Week> --start_time <HH:MM> --stop_time <HH:MM> --name --replication  

  schedule --delete --day <Day of the Week> --name --replication

For full details on running the cleaner schedule commands, help is available by entering:

  schedule --help

You can view replication details and status on the Replications page in the QoreStor GUI by selecting a replication and clicking to expand and view details.
