Scrubbing a Storage Pool (CLI)

Scrubbing a storage pool verifies the content by checking for errors. If any unrecoverable errors are found, either through a scrub or through normal operation, the CLI displays the affected files. If desired, the scrub process can be stopped before completion.

In general, a scrub should be performed as often as your oldest backup expires, at a minimum. The recommended time frame for performing a scrub is quarterly. A scrub should also be run before performing a software upgrade.

1. Go to configuration storage.
2. If you have multiple pools, a default pool is selected and displayed. If this is not the pool you want to scrub, enter set pool= and specify another online pool.

   Note -  If you have a single pool, the pool name is not displayed, but it is selected.

   ---

   hostname:configuration storage (pool0)> set pool=pool1
                             pool = pool1

3. Enter scrub start.

   hostname:configuration storage (pool1)> scrub start

4. (Optional) Stop the scrub before it has completed by entering scrub stop.

   hostname:configuration storage (pool1)> scrub stop

   Entering scrub start again resumes the scrub from where it was stopped.
