“need-sync” mirror disk should be synchronized as soon as possible.
2.1.5 Synchronize Mirror Disk
For RAID 1, it must be synchronized when data on the mirror disk is not identical with its corresponding source disk. Sometimes the data on the
mirror disk may be newer than the source disk. For example, the source disk is absent and the mirror disk runs in the tolerance mode. So the
exact meaning of “Synchronize Mirror” is to keep the data on a pair of the source and the mirror disks identical. RAID software always marks
the mirror disk with a “need-sync” icon
even though the mirror disk may have the correct data.
1. Select RAID 1. Right-click the selected RAID, then a shortcut menu will appear. Click “Synchronize Mirror” to synchronize the source and the
mirror disks.
2. When synchronization starts, a dialog will show the process. You can pause or cancel this process at any time.
3. A message will pop up when synchronization is finished.
