Scrubbing a Storage Pool – Scheduled (BUI)

Scrubbing a storage pool verifies the content by checking for errors. By default, scheduled storage pool scrubbing is enabled and set to every 30 days. Use the Scrub Schedule control to specify a different scrub interval or to disable scrub scheduling.

You cannot change the scrub priority explicitly. Scrub priority is automatically adjusted based on the specified scrub interval, the progress of the scrub, and the system load. Scrub priority automatically increases on an idle system.

A scrubbing operation will not proceed if a scrubbing or resilvering is already in progress. If a scrubbing operation is in progress when a resilvering starts, the resilvering operation suspends the current scrubbing and restarts the scrubbing after the resilvering is complete.

  1. From the Configuration menu, select Storage.
  2. From the Available Pools list, select the online pool to configure for scheduled scrubbing.
  3. Optional: Check the status of the last scrub.

    The Scrub Status field shows when the last scrub completed in local time (or how long the scrub ran if it did not complete), and the number of errors that were reported by the scrub.

    The zpool status command also reports the completion time of the last scrub, how long the scrub ran, and whether errors were found and repaired.

  4. Select Scrub Schedule.

    Choices on the Scrub Schedule drop-down menu are:

    • Off

    • 15 days

    • 30 days

    • 45 days

    • 60 days

    • 75 days

    • 90 days

    By default, scrub is scheduled for every 30 days. You can select a different scrub interval or, to disable scheduled scrubbing, select Off.

  5. Click the SCHEDULE button.
