Scrubbing a Storage Pool – Manual (BUI)

Scrubbing a storage pool verifies the content by checking for errors. Scheduled storage pool scrubbing is enabled by default, as described in Scrubbing a Storage Pool – Scheduled (BUI). The recommended minimum period for performing a scrub is quarterly.

• A scrub should be performed at least as often as your oldest backup expires.

• A scrub should also be run before performing a software upgrade.

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 scrub.
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. Click SCRUB.

   The Scrub Status field is updated.

5. Optional: To stop the scrub, click CANCEL.

   Clicking SCRUB again restarts the scrub.
