Maintenance

The QoreStor CLI maintenance commands lets you display the system maintenance repair progress, and manage the data repair and state of a QoreStor system.

NOTE: Whenever the QoreStor enters or exits from the Maintenance mode state, communication via OST, RDA, CIFS, and NFS is lost.

The maintenance --filesystem commands perform maintenance operations on the QoreStor file system, the maintenance --diags command allow you to create and view diagnostic bundles for your QoreStor system.

NOTE: This set of maintenance commands provide some functionality that is not available in the QoreStor GUI. To check the status of the QoreStor server, use the QoreStor CLI system --show command to display the current status.

This topic introduces the maintenance command usage:

NOTE: Using some of the maintenance command options could result in the deletion of data. Carefully observe the warnings (for example, running the scan without running the repair). If you have questions, do not perform these QoreStor CLI command options without first contacting Technical Support.
