RAID 6 Reed-Solomon Presets
Restorer Ultimate allows you to create and process RAID 6 layouts. You may use either presets for several RAID 6 layouts, or use your own custom ones.
Restorer Ultimate provides presets for the following RAID 6 layouts:
Creating a RAID 6 RAID 6 Reed-Solomon object from a preset:
We will use the Reed-Solomon (Left Synchronous (standard)) preset as an example. The RAID components are the images img1.bin, img2.bin, img3.bin, img4.bin, and img5.bin on the Device/Disk list.
To create a RAID 6 object
Note: Components should be placed in the same order and the offsets should be specified as they were in the original volume set. If this order is incorrect, you must change it by using the Move Up and Move Down buttons.
If a component from the objects is absent (due to hardware failure, for example), you can add a "missing disk" to re-construct the RAID. The missing disk should be placed in the same order as in the original RAID structure.
Turning Disks On-Line and Off-Line on-the-fly
You may turn the objects in the virtual RAID or volume set on-line and off-line by selecting/clearing the On checkbox on the Create Virtual RAID dialog box. It may be useful, for example, if you need to see which disk is non-actual in a RAID5 or 6.
Actually, when you turn an object off-line, Restorer Ultimate substitutes it with a Missing Disk or Empty Space object.
Note: Restorer Ultimate does not write anything real on the disk. A missing disk is a virtual object that does not affect actual data on the drive.
Specify Blocks order (Left Synchronous (standard) for our case) for virtual RAID 6. You may select it on the Blocks order drop-down or contextual menu. Also the RAID block size and Offset (in sectors) parameters must be set.
If the those parameters are not correct, data on the parents will not be damaged, but they cannot be recovered.
If Restorer Ultimate detects a valid file system on this RAID object, a partition object will appear on the Device/Disk list.
Note: You may check how correctly you have reconstructed the original volume set or RAID. Find a file and preview it. If the file appears correct, you have created a correct RAID layout. The file should be large enough. For example, it should have size equal or larger to Block size*(Number of disks-Number of parity disks) for RAID 5 or 6.
The Description Files for RAID Configurations topic shows the RAID description file for this RAID configuration.
