Example 4 with OnTimerMethodAnnotation

use of org.ovirt.engine.core.utils.timer.OnTimerMethodAnnotation in project ovirt-engine by oVirt.

the class GlusterSyncJob method refreshLightWeightData.

/**
 * Refreshes details of all volume across all clusters being managed in the engine. It can end up doing the
 * following in engine DB to make sure that the volume details in engine DB are in sync with GlusterFS:<br>
 * <li>Insert volumes</li><li>Delete volumes</li><li>Update properties of volume e.g. status, volume type</li><li>
 * Add / remove bricks to / from volumes</li><li>Set / Unset volume options</li><br>
 * These are all fetched using the 'volume info' command on gluster CLI, which is relatively lightweight, and hence
 * this method is scheduled more frequently as compared to the other method <code>refreshHeavyWeightData</code>,
 * which uses 'volume status' to fetch and update status of volume bricks.
