-h2. Enable delete operations on keepstore volumes
-
-Ensure your keepstore services have the "delete" operation enabled. Otherwise, even when unneeded data is identified by keep-balance, it will never be deleted from the underlying storage devices.
-
-Either use the @EnableDelete@ flag in your YAML configuration file @/etc/arvados/keepstore/keepstore.yml@:
-
-<notextile>
-<pre><code>...
-BlobSigningKeyFile: /etc/keepstore/blob-signing.key
-<span class="userinput">EnableDelete: true</span>
-Listen: :25107
-...
-</code></pre>
-</notextile>
-
-Or use the @-never-delete=false@ command line flag in your run script:
-
-<notextile>
-<pre><code>keepstore <span class="userinput">-never-delete=false</span> -volume=...
-</code></pre>
-</notextile>
