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:
- On the navigation menu, click Local Storage to expand the menu, then click Cleaner..
- On the Cleaner page, click Edit Schedule.
The schedule lists a Start Time and End Time for each day of the week.
- For each day of the week, click the time selector field. Select the From and To times to configure a window during which replication can run. Click Set.
- Click Save Schedule.
- 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. |
- Access the QoreStor command line interface.
- 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
On the Cleaner page, you can also view graphs showing Cleaner runtime and bytes processed. You may also use the stats --system command to view the cleaner status via the QoreStor command line interface.
